Sort в командной строке windows

on December 26, 2011

sort filename

sort filename /o outputfile

sort data.txt /o sorteddata.txt

sort data.txt > sorteddata.txt

sort /R filename /o outputfile

sort /M 10240 data.txt /o sorteddata.txt

Фильтр команды используется с символом перенаправления канала команды (|) и является командой внутри команды, которая считывает ввод команды, преобразовывает ввод, а затем записывает выход. Команды-фильтры дают возможность сортировать, просматривать и отбирать часть выходной информации других команд.

Фильтры делят, переупорядочивают или выделяют отдельные части из проходящей через них информации. В приведенной ниже таблице перечислены команды-фильтры, доступные в Microsoft Windows XP и выше.

Для направления данных из файла на вход фильтра используется символ «меньше» (<). Для направления на вход фильтра выхода другой команды используется канал (|).

Использование команды more

Команда more выводит содержимое файла или выхода команды в одном окне командной строки за раз. Например, чтобы отобразить содержимое файла List.txt в одном окне командной строки за раз, введите следующую команду:

more < list.txt

Отображается одно окно командной строки со сведениями, а затем в нижней части окна командной строки отображается строка — More —. Для перехода к следующему окну командной строки, нажмите любую клавишу на клавиатуре, кроме клавиши PAUSE. Для остановки просмотра следует ввести комбинацию CTRL+C.

Команда more полезна при работе с командами, создающими выход более одного окна командной строки. Например, при выводе дерева каталогов жесткого диска. Если на диске содержится больше каталогов, чем может быть одновременно выведено в окне командной строки, можно использовать команду tree с каналом (|) и команду more.

tree c:\ | more

На экран будет выведен первое окно командной строки с выходом команды tree, а затем отобразится строка — More —. Выход будет ожидать нажатия любой клавиши для продолжения (кроме клавиши PAUSE).

Использование команды find

Команда find проводит поиск заданной строки или текста в файлах. Команда Cmd.exe отображает каждую строку, которая совпадает со строкой или текстом, указанным в окне коммандной строки. Команда find может быть использована как команда-фильтр и как обычная команда Microsoft Windows XP. Дополнительные сведения об использовании команды find в качестве стандартной команды см. в разделе Find.

Чтобы использовать команду find в качестве команды-фильтра, необходимо включить символ «меньше» (<) и строку или текст, в котором требуется выполнить поиск. По умолчанию при поиске команда find учитывает регистр. Например, следующая команда будет искать строку «Pacific Rim» в файле Trade.txt:

find "Pacific Rim" < trade.txt

Выход не включает вхождение строки «pacific rim». Встречается вхождение строки «Pacific Rim» с прописными буквами.

Для сохранения результатов работы команды find (вместо отображения их в окне командной строки), введите символ «больше» (>) и имя файла, в котором требуется хранить выход. Например, следующая команда ищет строку «Pacific Rim» в файле Trade.txt с сохранением результата в файле Nwtrade.txt:

find "Pacific Rim" < trade.txt > nwtrade.txt 

Использование команды sort

Команда sort выполняет сортировку по алфавиту текстового файла или выхода команды. Например, следующая команда сортирует содержимое файла List.txt и отображает результаты в окне командной строки:

sort < list.txt

В этом примере команда sort сортирует строки файла List.txt в алфавитном порядке и выводит результат на экран без изменения файла. Для сохранения результатов работы команды sort (вместо их отображения) введите символ «больше» (>) и имя файла. Например, следующую команду можно использовать для алфавитной сортировки строк файла List.txt и сохранения результатов в файле Alphlist.txt:

sort < list.txt > alphlist.txt

Для сортировки вывода команды следует ввести команду, затем символ канала (|) и команду sort (команда | sort). Например, следующая команда сортирует в алфавитном порядке строки, которые содержат слово «Jones» (вывод команды find):

find "Jones" maillst.txt | sort 

Introduction

The Windows operating system features over 280 commands for CMD (Command Prompt). Some commands are specific to Windows servers, while others are available for desktop versions. In both cases, CMD commands communicate directly with the OS and allow to perform various IT automation tasks.

This guide showcases important Windows CMD commands and provides hands-on examples.

Prerequisites

• Access to the command prompt (CMD).
• Administrator privileges (for some commands).

Commands are built-in programs that run through the Command Prompt program. The main use for commands is to automate various tasks, such as user provisioning and other routine actions.

Below is an overview of some common Windows CMD (Command Prompt) commands. Every command has a brief explanation and an example use case.

1. arp Command

The arp (address resolution protocol) command shows and modifies entries in the ARP cache. The cache contains one or multiple tables that map IP addresses to resolved physical addresses.

The syntax for the command is:

arp <options> <address>

Without any parameters, the arp command shows the help window.

To show the ARP cache table, run the following command:

arp -a

The output lists all the current ARP entries grouped by the interface.

2. assoc Command

The assoc (association) command lists and modifies file extension associations on the system. The syntax for the command is:

assoc .<extension>=<filetype>

Without any parameters, the command prints the current file extension associations.

Use the assoc command to view, change, or remove file associations. For example, to view the .log file associations, run:

assoc .log

Change the file association with:

assoc .log=txtfile

Alternatively, remove all file associations for files with the .log extension by running:

assoc .log= 

The command requires adding a space after the equals sign to remove the association.

3. attrib Command

The attrib (attribute) command shows or changes file attributes. The possible attributes are:

• R — Read-only.
• H — Hidden.
• S — System file.

The syntax for the attrib command is:

attrib <+ or -> <attribute>

The plus sign (+) sets an attribute, while the minus sign (-) removes an attribute from a file. Without any options, the command shows the file attributes in the current directory.

To set a file to have the read-only (R) and hidden (H) attributes, use the following command:

attrib +R +H sample_file.txt

To make a file visible, remove the hidden (H) attribute:

attrib -H sample_file.txt

The minus removes the attribute from the file and returns the file to the default visible state.

4. bcdboot Command

The bcdboot (boot configuration data boot) command sets up a system partition by copying BCD files into an empty partition.

The syntax for the command is:

bcdboot <path>

For example, to copy the BCD files into C:\Windows, use:

bcdboot C:\Windows

The output prints a confirmation message about file creation.

5. cd Command

The cd (change directory) command shows or changes the current location. The syntax for the command is:

cd <directory>

The directory parameter is optional, and without it, the command prints the current working directory.

For example, to change the location to a directory named Public, add the directory name after the command:

cd Public

The prompt reflects the change and shows the new location.

To change the location to a different disk, add the /d option before the path. For example, to change to disk S:\ use:

cd /d S:

Without the option, the command prints the path without changing to the provided location.

To change to the parent directory, use the following shortcut:

cd ..

The current directory changes to one directory above the current location.

6. chkdsk Command

The chkdsk command scans the local file system and metadata for errors. The syntax for checking a disk is:

chkdsk <volume> <options>

Without additional parameters, the chkdsk command shows the current disk state without fixing any errors.

Additional parameters enable fixing errors on a disk, such as the /f option:

chkdsk <volume> /f

The command attempts to fix errors on the disk. If the disk is in use, run the check on the next system restart. Stopping the command does not affect the system, but ensure to run the scan later to fix any potential data corruption.

7. choice Command

The choice command prompts a user to choose an answer from a list of options. Without any parameters, the command prompts the user to choose between Y and N options.

Additional options control the number of choices and the prompt text. For example, to add a third choice, use the /c parameter and list the three option names:

choice /c ync

Insert additional text to explain the available options with the /m parameter. For example:

choice /c ync /m "Yes, No, Continue"

In all cases, the command returns the choice index and exits.

8. cipher Command

The cipher command shows and modifies the encryption for files or directories. The command syntax is:

cipher <option> <file or directory>

Without any options, the cipher command shows the encryption state for all files and directories in the current location. The U represents «unencrypted,» whereas E is «encrypted.»

To encrypt a file in the current directory, use the /e parameter:

cipher /e <file name>

The file’s indicator changes from U to E, which marks the file as encrypted.

9. clip Command

The clip command copies a command output or file contents to the clipboard. The syntax for copying a command’s output in CMD is:

<command> | clip

For example, to copy the current directory path, pipe the cd command to clip:

cd | clip

Paste the contents anywhere in the window using CTRL+V (or right-click in CMD).

To copy the contents of a file, use redirection:

clip < <filename>

For example, to copy the contents of a sample.txt file to the clipboard, run:

clip < sample.txt

The file’s contents are saved to the clipboard and can you can paste them anywhere.

10. cls Command

The cls command clears the text in a command prompt window and returns a blank surface. Use the command to clear the screen contents.

Note that the previous contents and output do not return to the screen.

11. cmd Command

The cmd command starts a new instance of the command interpreter. Use the following syntax to run the command:

cmd <options> <command>

Without additional parameters, the cmd command shows the current cmd.exe program version.

Use cmd to run commands without affecting the current session. For example, to test a command and return to the current command interpreter session, use the /c parameter:

cmd /c cd ..

The new interpreter changes the directory. However, the /c tag ensures the interpreter returns to the original session, and the directory stays unchanged.

To run a command and stay in the new session, use the /k parameter:

cmd /k cd ..

The /k parameter switches to the new session and runs the cd command to switch to the parent directory.

12. color Command

The color command changes the default console background and text colors. The command syntax is:

color <background><font>

The color attributes are hexadecimal numbers from 0 to f. The help window displays all the possible color options:

help color

For example, to change the background to blue (1) and the font to light aqua (b), run:

color 1b

To return to the default console colors, run the color command without options.

13. comp Command

The comp command compares the contents of two files. The comparator program inspects file bytes and outputs characters where the two files differ.

The syntax for the command is:

comp <file 1> <file 2> <options>

Without any options, the comp command starts an interactive prompt to enter file names and additional options.

To demonstrate how the command works, compare two text files with the following contents:

• sample_file_1.txt contains «test»
• sample_file_2.txt contains «text»

Run the comp command and provide the two file names:

comp sample_file_1.txt sample_file_2.txt

The output prints the comparison error as characters in hexadecimal format and asks to compare more files (enter N to exit).

To print the comp results in human-readable format, use the /a parameter:

comp /a sample_file_1.txt sample_file_2.txt

The comparison fails at character «s» in the first file and character «x» in the second file.

14. compact Command

The compact command is a built-in feature for compressing files and folders. The syntax for the command is:

compact <options> <file>

Without any options or parameters, the compact command prints the compression state in the current directory.

For example, to compress a file, use the /c parameter and provide the file name:

compact /c sample_file.txt

To uncompress a file, use the /u parameter:

compact /u sample_file_1.txt

Use the compact command to save disk space and compress large files and directories.

15. copy Command

The copy command copies one or multiple files from one location to another. The command syntax is:

copy <options> <source> <destination>

For example, to copy a file’s contents into a new file in the same location, use:

copy sample_file.txt sample_file_copy.txt

The command creates the new file and copies all the contents from the source file.

16. date Command

The date command shows and modifies the current date on the system. Without any parameters, the command prints the current date and requests to enter a new date:

date

Enter the date as mm-dd-yyyy to change the current date on the system or exit with CTRL+C.

Use the /t parameter to avoid modifying the system state and only print the current date:

date /t

The command shows the day of the week and the current date.

17. defrag Command

The defrag (defragmentation) command finds and aggregates fragmented files on the system. The command reduces unnecessary empty data blocks and improves system performance.

The syntax for the defrag command is:

defrag <volumes> <options>

For example, to defragment the C:\ drive, run:

defrag C:\ /u /v

The /u parameter prints the progress, while /v shows a verbose output. These parameters are optional.

18. del and erase Commands

The del and erase commands delete one or more files. The syntax for the commands is:

del <options> <file(s)>

erase <options> <files(s)>

Both commands permanently delete the specified file or files from a disk and are irretrievable.

For example, to delete a file with the name sample.txt, run:

del sample.txt

Or alternatively:

erase sample.txt

To avoid accidental deletion, use the /p parameter:

del /p sample.txt

The output shows a prompt with the file name and requires confirmation before deleting the file.

19. dir Command

The dir (directory) command lists directory contents, including files and subdirectories. The syntax for the command is:

dir <drive><path><filename> <options>

The dir command without options shows information for the current directory.

To show the C:\ drive contents, run:

dir C:\

The output shows the following information:

• Volume drive.
• Volume serial number.
• Directory contents with modification time.
• File and directory count.

20. doskey Command

The doskey command starts the Doskey.exe program for the previously entered commands. The command helps recall command history and create macros.

For example, to see the command history from the current command prompt session, run:

doskey /history

The output shows all the commands from the CMD session from oldest to newest.

21. driverquery Command

The driverquery command is a command for admins to display the installed device drivers and their information. The command works for both local and remote access machines.

The syntax for the command is:

driverquery <options>

Without any options, the driverquery command shows device drivers on the local machine. Additional options control the output format or allow querying remote machine drivers.

22. echo Command

The echo command prints a message to the console and controls the settings for the command. The syntax for the command is:

echo <message>

Without any parameters, the command shows the current settings.

To use the command and show a «Hello, world!» message to the screen, run:

echo "Hello, world!"

The echo command often appears in scripts to print useful information while the script runs.

23. exit Command

The exit command ends the current batch script or the command interpreter session. To exit a batch script, add the /b parameter:

exit /b

Without the /b option, the exit command closes the command interpreter.

24. fc Command

The fc (file compare) command compares two or more files. The output prints the contents to the console if there is a difference between the files.

The syntax for fc is the following:

fc <options> <file 1> <file 2> 

For example, to compare two sample files, sample_file_1.txt and sample_file_2.txt, run:

fc sample_file_1.txt sample_file_2.txt

The command prints the file contents, indicating there is a difference between the two files.

25. find Command

The find command searches for a string in a file and prints the line of text when there is a result. The command syntax is:

find <string> <file>

For example, to search for the string «text» in a file, use:

find "text" <file>

The command looks for an exact match and returns the file name along with the line of text that contains the string. If a file does not contain the text, the command returns the file name without the text.

26. findstr Command

The findstr (find string) command performs a similar task to the find command. The command returns the whole line where the text is located without the file name. This feature makes it more convenient for use in scripts.

The command syntax is:

findstr <string> <file>

For example, to find a string «text» in a file, run:

findstr "text" <file>

If the command does not return a result, the string is not in the file.

27. ftype Command

The ftype (file type) command shows and changes a file type and extension association. The command syntax is:

ftype <file type>=<open command>

The file type parameter is the file to show or modify (such as txtfile), while the open command option is a string that calls a program to read the file type. The open command string substitutes the file name into the open command to run a file in the provided program.

Without any options, ftype prints all file types and extension associations.

To show the current file type and extension association for text files, enter:

ftype txtfile

To remove file type association, append an (=) sign:

ftype txtfile=

The command omits the program for opening files and removes the program association.

28. getmac Command

The getmac command fetches the MAC addresses for all network cards on the computer or in the network. The command also shows the protocols associated with each address.

The syntax is:

getmac <options>

Additional options provide detailed information about a remote computer or control the output display. For example, to show the MAC addresses in the CSV format, use:

getmac /fo csv

Use the command to parse the MAC address to a network monitoring tool or to check the protocols on network adapters.

29. help Command

The help command shows detailed information for a specific command. Without any parameters, the help command lists all available system commands.

The syntax for the command is:

help <command>

For example, to view the help menu for the cd command, run:

help cd

Use any key to go through the pages if the help page is larger than the command line. Alternatively, press CTRL+C to exit.

<command> /?

30. hostname Command

The hostname command is a simple command to display a machine’s host name. Run the command to see the name of the computer:

hostname

The command does not have options, and providing any additional parameters throws an error. The hostname command is available for systems with TCP/IP installed on a network adapter.

31. ipconfig Command

The ipconfig (IP configuration) command is a networking CMD tool that shows all current TCP/IP network configuration information. The command also refreshes DHCP and DNS settings.

The syntax for the command is:

ipconfig <options>

Omitting options shows the basic TCP/IP configuration for all adapters:

ipconfig

To show the full TCP/IP configuration for all adapters, run:

ipconfig /all

Renew the DHCP IP address for the local area connection with:

ipconfig /renew Local Area Connection

To flush the DNS cache, use:

ipconfig /flushdns

Use the command when troubleshooting DNS issues.

32. label Command

The label command shows, changes, or removes the volume label (name) of a disk. The command requires administrator privileges to perform any changes.

Without any options, the label command shows the label for the C:\ drive and starts a prompt to change the name:

label

Press Enter to remove the label, or enter a new name to change the current label name. Confirm the change with Y or press N to keep the existing name.

33. makecab Command

The makecab command creates a cabinet (.cab) file. Cabinet files are an archive format specific to Windows systems with support for lossless data compression and archive integrity.

Use the following syntax to create .cab files with the makecab command:

makecab <options> <source> <destination>

For example, to create a sample_cab.cab file in the current directory and add a sample_file.txt file to the archive, use:

makecab sample_file.txt sample_cab.cab

The output prints the compression progress and exits when done.

34. md and mkdir Commands

The md and mkdir (make directory) commands create a new directory or subdirectory. The command syntax is:

md <path>

mkdir <path>

For example, to make a new subdirectory called Subdir in the current location, run:

mkdir Subdir

The command extensions enable md and mkdir to create a directory tree:

md Subdir\Subsubdir

The command immediately creates all intermediate subdirectories.

35. mklink Command

The mklink (make link) command creates a hard or symbolic link to a file or directory. The command requires administrator privileges to run and uses the following syntax:

mklink <options> <link> <target>

Without any additional options, the mlink command creates a symbolic link to a file. For example:

mklink my_link sample_file.txt

To create a hard link instead of a symbolic link, use the /h parameter:

mklink /h my_link sample_file.txt

Create a directory link with the /d parameter:

mklink /d \Docs \Users\milicad\Documents

The dir command shows the links in the directory listing. To enter the directory, use the cd command and treat the link as a regular directory (cd Docs).

36. more Command

The more command is a Windows CMD utility for displaying long documents or outputs one screen at a time. To use more with a command, use the pipe character:

<command> | more <options>

Alternatively, use the command to display long files page by page:

more <path>

For example, run the help cd command and pipe the more command to truncate the output:

help cd | more

Press Enter to go to the following line and Space to go to the next page. To exit, press q.

37. mountvol Command

The mountvol command creates, removes, or shows a volume mount point. Mounting a volume makes data on a storage device available for local users through the file system.

The command syntax is:

mountvol <path> <volume name>

The command does not require a drive letter to link a volume. Without any parameters, the mountvol command shows the help menu, mount points, and possible volume names.

For example, to list the volume name and current mount point for the C:\ drive, run:

mountvol C:\ /l

The output shows the GUID for the volume, which is a unique unchanging identifier.

38. move Command

The move command is a CMD shell command for moving files from one location to another. The syntax for the command is:

move <options> <source> <destination>

The source and destination are either a folder or a file. The move command renames a file if the source and destination locations are the same but have different file names.

For example, the following command renames a file named sample_file.txt to file.txt:

move sample_file.txt file.txt

Provide the full path to move a file to another location:

move C:\Users\Public\Downloads\my_file.txt C:\Users\Public\Desktop\my_file.txt 

If overwriting an existing file, the command prompts to confirm, unless the command runs as part of a batch script.

39. msiexec Command

The msiexec program runs the Windows Installer program for installing, managing, and removing .msi software packages. The command syntax is:

msiexec <options> <path to package>

The program features various install, display, update, and repair options. Without any options, the msiexec command opens a window to show the command information.

For example, to perform a normal installation of a .msi package, run:

msiexec /i "C:\example.msi"

The /i option indicates a normal installation of the .msi package located at the provided path.

40. msinfo32 Command

The msinfo32 command opens the System Information window, which has details about the system.

The command syntax is:

msinfo32 <options>

Additional options filter the information or export the data into specific file formats. For example, to export all system information into an.nfo file, use:

msinfo /nfo sysinfo.nfo

The command automatically appends the .nfo extension if omitted.

41. mstsc Command

The mstsc command starts the Remote Desktop Connection (RDC) program to connect to a remote machine. Use the command for remote connection or to alter an existing .rdp file.

The command syntax is:

mstsc <options> <file>

For example, to start an RDC session in full-screen mode, use this command:

mstsc /f

To edit an existing connection, use the /edit parameter and provide the file name:

mstsc /edit example.rdp

User-created .rdp files are in the Documents folder by default.

42. net Commands

net commands are a set of commands for managing various network aspects, such as users and network services.

The command syntax is:

net <subcommand> <options>

Without additional parameters, the net command shows all available subcommands with a short description.

Use the net start command to list all running Windows services:

net start

To stop a service, use the following command:

net stop <service>

View the login and password requirements for a user with the following:

net accounts

Display additional help for a subcommand using the following syntax:

net help <command>

The output shows a detailed help window for any provided command.

43. netstat Command

The netstat (network statistics) command is a crucial command for network administrators. The command lets you view various network statistics.

The basic syntax for the command is:

netstat <options>

The command displays active TCP connections when used without options. The output shows the protocol, local and foreign addresses, and the TCP connection state.

Add the -a option to display all active TCP connections and listening TCP and UDP ports:

netstat -a

Use the command to scan for open ports or to check the port protocol type.

44. nslookup Command

The nslookup command is a DNS infrastructure diagnostics tool for web servers. The command features a non-interactive mode for looking up a single piece of information and an interactive mode for looking up additional data.

The syntax for nslookup is:

nslookup <host> <command> <options>

Without any options, nslookup enters interactive mode. To find DNS records for a specific domain name, use:

nslookup <domain>

The output prints the A records for the provided domain.

45. path Command

The path command helps add directories to the PATH environment variable. The variable contains a set of directories that point to executable files.

The command syntax looks like the following:

path <location>

Without any parameters, path shows the current state of the PATH variable.

To add multiple locations to PATH, separate each location with a semicolon (;) as in the following example:

path <location 1>; <location 2>

Both locations append to the variable.

46. ping Command

The ping command is another essential network troubleshooting tool. The command checks the connectivity with another machine by sending ICMP request messages.

The syntax for the command is:

ping <options> <host>

For example, to check connectivity to the phoenixNAP website, use:

ping phoenixnap.com

The output prints corresponding reply messages and round-trip times. Use the command to check for connectivity and name resolution issues.

47. powercfg Command

The powercfg (power configure) command runs the powercfg.exe program for controlling the system’s power plans. The monitoring tool also helps troubleshoot battery life and energy efficiency problems on a device.

The command syntax is:

powercfg <options> <arguments>

To list the current power plan setup on a device, use:

powercfg /list

The output lists all power schemes on the system. The active power scheme has an asterisk (*).

48. prompt Command

The prompt command allows changing the CMD prompt display to the specified string. By default, the prompt shows the current location and the greater-than sign (>).

The command syntax is:

prompt <string and variables>

The prompt command offers various variables to add special characters or additional features to the prompt. For example, to change the prompt to an arrow, use:

prompt --$g

The $g variable represents the greater-than sign (>) and the prompt stays during the command-line session.

49. rd and rmdir Commands

The rd and rmdir commands remove an empty directory from the system. The syntax for the commands is:

rd <path>

rmdir <path>

Attempting to delete a directory with files results in an error message. Add the /s parameter to delete a directory with subdirectories and files to avoid the error message:

rd /s <path>

The command deletes the complete subdirectory tree and all files.

50. ren and rename Commands

The ren and rename commands rename files or directories. The syntax for the two commands is:

ren <path><old name> <new name>

rename <path><old name> <new name>

The commands do not allow moving the files to a different location. Wildcard characters work for multiple files. For example, to change all .txt files to .c files, use:

ren *.txt *.c

The asterisk (*) character helps discover all file names in the current directory with the .txt extension and renames the files to have the .c extension.

51. robocopy Command

The robocopy command is a robust command for copying files and directories. The syntax for the command is:

robocopy <source> <destination> <file> <options>

The main benefit when using robocopy is the /mt parameter for higher-performance multithreading. Additionally, the /z parameter lets you restart a transfer in case of interruptions.

An example transfer looks like the following:

robocopy C:\Users\user\Downloads C:\Users\user\Documents database.db /mt /z

Use the command for large file transfers that are sensitive to interruptions.

52. route Command

The route command shows and alters entries in the local routing table. The command syntax is:

route <options> <command> <value>

The different available commands are:

• add — Adds a route entry to the table.
• change — Modifies an entry in the table.
• delete — Removes a route from the table.
• print — Displays a route or routes.

For example, to print all routes from the table, use:

route print 

The output prints the interface list, and IPv4 and IPv6 routing tables.

53. schtasks Commands

The schtasks command helps schedule commands or programs to run on the system. The tasks run at specified times or periodically. The syntax for the commands is:

schtasks /<subcommand>

The following subcommands are available:

• change — Modifies existing properties of a task.
• create — Creates a new task.
• delete — Removes a task.
• end — Stops a program started by a task.
• query — Prints scheduled tasks on the machine.
• run — Starts a scheduled task.

For example, to show currently scheduled tasks on the system, use:

schtasks /query

The output displays task names, next run times, and task statuses.

54. set Command

The set command shows, sets, and removes environment variables in the CMD. The syntax for the command is:

set <variable>=<value>

Without additional parameters, the set command shows all environment variables.

The variables are available to use with any command. For example, to create a new CMD variable called message, use:

set message="Hello, world!"

Reference the variable using the following syntax:

echo %message%

Encasing the variable in the percent signs (%) reads the value and outputs it to the screen.

55. sfc Command

The sfc (system file checker) is an administrator command for checking protected file version integrity. The command also replaces incorrect overwritten protected files with the correct file version.

The syntax for the command is:

sfc <options> <files or directories>

For example, to scan the system and repair all files, use the following command:

sfc /scannow

The command scans all protected system files and repairs problematic files when possible.

56. shutdown Command

The shutdown command restarts or shuts down a local or remote computer. The command syntax is:

shutdown <options>

Without any arguments, the shutdown command opens the help menu.

For example, to shut down and restart the computer, use the /r option:

shutdown /r

To shut down without restarting, use the /s argument:

shutdown /s

In both cases, the shutdown is not immediate. To cancel the action, use the /a option:

shutdown /a

The option ensures that a previously executed shutdown command aborts.

57. sort Command

The sort command allows sorting provided data from a file or user input. Additional options control the sorting mechanism and from which point to start sorting.

To use the command interactively, do the following:

1. Run sort without any options.

2. Enter a new word in each line.

3. Press CTRL+Z and Enter at the end of the list to sort the input values alphabetically.

Alternatively, use the sort command on files:

sort sample_file.txt

The command sorts the file contents and prints the result to the console.

58. start Command

The start command opens a new command-prompt window according to the specified options. The command syntax is:

start <title> <options>

For example, to load start a new command-prompt session with the title «Hello, world!» and set the path to C:\. enter the following command:

start "Hello, world!" /d C:\

A new CMD window opens with the starting path on the C:\ drive and a custom title.

59. systeminfo Command

The systeminfo command displays detailed system information about the OS and computer, including hardware properties. The command works on both local and remote machines.

Use the command without options to show the local system information:

systeminfo

Additional options allow checking system information for remote computers or controlling the output format. For example, show the output in CSV format with:

systeminfo /fo csv

Different formats enable parsing the information through scripts effectively.

60. takeown Command

The takeown (take ownership) command allows an administrator account to take ownership of a file. The command provides access to a file for an administrator and makes the administrator the owner.

Add the /f option and specify the file name:

takeown /f <file>

The administrator now has full permissions over the file.

61. taskkill Command

The taskkill command ends a running process or task on the Windows system through the command line. Use the command to forcefully end processes and tasks which did not end correctly.

The syntax for the command is:

taskkill <options> <task or process>

A common way to end a task is to find the process ID (PID) with the tasklist command and end the process with:

taskkill /pid <Process ID>

The command finds the process by ID and kills it.

62. tasklist Command

The tasklist command shows all running processes on a local or remote computer and their memory usage. The command helps locate and reference specific processes.

The syntax for tasklist is:

tasklist <options>

Without additional options, the command shows all currently running processes.

The image name and PID are unique identifiers for a process. The final column shows the memory usage for a process. This is a good indicator for identifying processes that slow down the system.

63. telnet Command

The telnet command is a Windows tool for bidirectional CLI communication. The tool uses the Telnet protocol to send messages and enable an interactive communication channel.

The syntax for the command is:

telnet <command> <options>

See our detailed guide for using Telnet on Windows.

64. time Command

The time command manages and displays the current system time. Without any options, the command prints the current time and prompts to enter a new time:

time

Enter a new time to change the system time or exit the prompt using CTRL+C. Use the /t option to avoid making modifications:

time /t

The command prints the current time and returns to the command line.

65. timeout Command

The timeout command pauses the command line for a specified number of seconds. The syntax for the command is:

timeout /t <seconds>

For example, to pause the interpreter for ten seconds, run:

timeout /t 10

The output counts down and returns to the command line. Press any key to interrupt the timeout earlier. Use the command in scripts to wait for execution between two commands.

66. title Command

The title command is a simple utility for changing the command prompt’s title. The syntax is:

title <string>

For example, to set the title to "Hello, world!", use:

title "Hello, world!"

The CMD window title changes to the provided string. Use the command when running multiple batch scripts to differentiate between different command prompts.

67. tracert Command

The tracert (traceroute) command is a networking tool for determining the path from a local computer to a destination. The command sends ICMP messages with increasing TTL values to map routers along the path.

The syntax for tracert is:

tracert <options> <destination>

For example, to trace the path to phoenixnap.com, use:

tracert phoenixnap.com

Alternatively, use the IP address of the destination.

The output shows the hops between the source and destination, providing an IP address and name resolution where applicable. Use the command to discover connectivity issues to a host.

68. tree Command

The tree command displays the contents inside a drive or directory in a tree-like structure. The syntax is:

tree <options> <path>

Without any options, the tree command displays the directory structure of the C:\ drive.

69. type Command

The type command is a built-in command for showing file contents. The command allows viewing a file directly in CMD without modifying the text.

The syntax for the type command is:

type <file path>

For example, to show the contents of the file called sample_file.txt, run:

type sample_file.txt

The output prints the file’s contents to the command line. Use this command to preview files directly in the command prompt.

70. tzutil Command

The tzutil (time zone utility) command helps modify and display the currently set time zone on the system. Without any options, the command shows the help window.

Display the current time zone with:

tzutil /g

The output shows the time zone ID. List all available time zone IDs with:

tzutil /l | more

The more command helps truncate long outputs. Use the /s parameter and provide the time zone ID to change the system time zone.

71. ver Command

The ver command is a simple utility to show the operating system version. Use the command to find the exact version of the operating system:

ver

The version prints to the output and returns to the command line.

72. vol Command

The vol command prints the disk volume and label. The syntax for the command is:

vol <drive>:

Without a specified drive, the vol command shows information for the currently selected drive.

73. where Command

The where command searches for the location of a file using a search pattern and prints the location to the command line. The syntax for the command is:

where <options> <location to search> <file name>

Omitting the location searches for the file in the current directory without going through subdirectories. To perform a recursive search, add the /r parameter. For example:

where /r C:\ sample_file.txt

The command searches the C:\ drive and all subdirectories. If the file is found, the command returns the location path.

74. whoami Command

The whoami command shows the current user’s domain and username. The syntax for the command is:

whoami <options>

Without options, the command shows the domain and user name.

Add the /all parameter to show detailed information for the current user:

whoami /all

The user’s name, security ID, groups, and privileges print to the console.

75. xcopy Command

The xcopy command copies files, directories, and subdirectories from one location to another. The syntax for the command is:

xcopy <source> <destination> <options>

For example, use the following command to copy contents from one location to another, including subdirectories (even if empty):

xcopy <source> <destination> /s /e

The /s parameter enables subdirectory copy, while /e includes empty directories. If any files with the same name exist in the destination, the command prompts before overwriting.
