Как запускать bash скрипты в windows

Шелл скрипты или .SH файлы похожи на командные файлы Windows, которые могут выполняться в Linux или Unix.

В Windows 10 можно запустить файл .sh или скрипт оболочки, используя подсистему Windows для Linux.

В этом руководстве мы покажем вам, как запустить файл скрипта оболочки в Windows 10.

Как запустить файл .sh или скрипт шелла в Windows 10

Bash – это оболочка и командный язык Unix, который может запускать файлы скрипты .sh.

Вам не нужно устанавливать Ubuntu или любые другие дистрибутивы Linux, если ваши скрипты не нуждаются в поддержке реального ядра Linux.

Мы поделимся обоими методами.

• Выполнить файл скрипт оболочки, используя WSL
• Выполнить скрипт оболочки с помощью Ubuntu в Windows 10

1] Выполнить файл скрипта оболочки, используя WSL

Установите WSL или Windows Subsystem для Linux

Перейдите в Настройки> Обновление и безопасность> Для разработчиков.

Проверьте переключатель режима разработчика.

Поищите «Функции Windows», выберите «Включить или отключить функции Windows».

Прокрутите, чтобы найти WSL, установите флажок и установите его.

После этого необходимо перезагрузить компьютер, чтобы завершить установку запрошенных изменений.

Нажмите Перезагрузить сейчас.

BASH отныне будет доступен в командной строке и PowerShell.

Выполнить файлы скриптов оболочки

• Откройте командную строку и перейдите в папку, где доступен файл скрипта
• Введите Bash script-filename.sh и нажмите клавишу Enter.
• Система выполнит скрипт, и в зависимости от файла вы должны увидеть вывод.

На платформе Linux вы обычно используете SH, но здесь вам нужно использовать BASH.

Тем не менее, BASH в Windows имеет свои ограничения, поэтому, если вы хотите выполнить их в среде Linux, вам нужно установить Ubuntu или что-то подобное.

2] Выполнить скрипт оболочки, используя Ubuntu в Windows 10

Убедитесь, что у вас установлена Ubuntu или любой другой дистрибутив Linux.

Ubuntu смонтирует или сделает все ваши каталоги Windows доступными в /mnt.

Таким образом, диск C доступен по адресу /mnt/C.

Таким образом рабочий стол будет доступен по адресу /mnt/c/users/<username>/desktop.

Теперь следуйте этим шагам

• В командной строке введите Bash, и система запустит приглашение дистрибутива.
• Перейдите в папку с помощью команды «cd» , где доступны скрипты.
• Введите «sh script.sh» и нажмите Enter

Система выполнит скрипт

Поскольку Linux теперь доступен в Windows, вам не нужно использовать какие-либо сторонние приложения, такие как Cygwin.

WSL должно быть достаточно для большинства скриптов, чтобы помочь вам запустить эти самые крипты оболочки в Windows 10.

Bash Shell scripts are text files ending with the .sh extension, and it contains coded information written for the Linux operating system. Script files are designed to perform a designated task when run through a computer program called BASH in the Linux platform.

However, the Windows operating system does not know the command language used inside the shell script files and therefore fails to execute shell scripts directly. If you want to know how to run a shell script in Windows, you have come to the right place. Read on to learn more about bash scripts.

What are Shell Scripts or SH files?

Shell script files (or SH files) contain one or more commands written in the BASH (Bourne-Again Shell) language and are used by multiple Linux programs. Software engineers developed these files to ease the workload and divide individual operations into numerous script files. Hence, they have a crucial role to play while creating a short but powerful computer program.

In Linux, these script files can be run in a terminal window by simply navigating to their location and typing their filename. In Windows, however, they require additional software or a Linux-like environment to execute bash scripts as batch files.

A Linux environment can be implemented in Windows through the latest inclusion of the Windows Subsystem for Linux (WSL) for Windows 10/11, through which various Linux script files or GUI can be executed through the Windows Bash Shell. Now without further ado, let us show you how to run shell scripts in Windows.

Batch files (or .bat files) are small coded programs for Windows that perform automated tasks with minimal effort. Similarly, a .sh script file performs the same job for Unix or Linux systems through the bash shell. Bash scripts consist of command line inputs (such as cd, md, mkdir) bundled together to perform at once upon execution. Moreover, it is possible to run Linux scripts in Windows 10/11 in the following ways:

1] Execute Shell Script file using Windows Subsystem for Linux

It is not possible to run script files through the command prompt or PowerShell terminal provided by Windows directly, but it is possible to run native Bash shell through the latest integration of WSL or Windows Subsystem for Linux being provided from Windows 10 Insider Preview Build 14316. The process involves a lot of steps as a whole, so we have divided it into 4 parts.

Part 1: Enable WSL and developer settings from Windows features:

• First, we need to enable the WSL Windows feature through the developer settings. It comes bundled with the Windows operating system and doesn’t require extra data from the internet. Enable developer settings through the steps below.
• Open Start Menu and click on the Gear icon to open the Settings app.

• Head over to the Update & Security section from the Settings menu.

• Click on the “For Developers” tab in the left pane and turn on the Developer mode using the button as shown.

• Select OK on the warning message.

• Inside the “Find a setting” search bar, type Windows features and click the option to “Turn Windows features on or off.”

• You will see a window pop-up listing all the different on-demand future or deprecated Windows features that users can enable anytime. Find Windows Subsystem for Linux among them, and mark the checkbox beside it. Click on OK to confirm the changes and proceed.

• Windows will spend some time Searching for the required files to enable the Windows subsystem.

• After acquiring the Windows files, the installation manager will apply changes, so wait for it patiently.

• On successfully completing the entire process of adding the Windows Bash, You will be asked to Restart your computer. You can either Restart now or later on your own, depending on if you have some scheduled tasks left.

Part 2: Download Ubuntu from the Microsoft Store and integrate with WSL:

• After restarting, open the Microsoft Store from the Start Menu.

• Search for Ubuntu in the App Store.

• Click on Get to download the Linux distro and wait patiently.

• Upon the completion of installation, open Ubuntu from the Start menu (From the recently added app section)

• A command prompt window opens up, and Ubuntu begins its original installation on your hard disk and its integration with the WSL to get access to Windows files.

• The Windows Bash window asks you to create an account (separate from your original Windows account). Type your desired username and password as login credentials. Remember them properly as they will be required later.
• After completion, you can run Bash scripts, Linux commands (sed, awk, mkdir), Linux tools (nano, vi, python) directly on Windows. You also access the Linux filesystem on Windows.

Part 3: Initialize the Newly installed Linux Distro:

• Most Linux distro downloaded from the app store arrive with a minimal package catalog. You need to update and upgrade these packages through these commands:sudo apt update && sudo apt upgrade. Internet connectivity is required for this process to download extra packages.

Part 4: How to run shell script in Windows Command Prompt

• Head over to the location in your Windows OS where the script files are stored as text files.

• Hold down the Shift key and right-click on an empty space inside the folder. Click on the Open command prompt here. In newer Windows installation, click on Open PowerShell Window here.
• Type bash inside the command prompt window or the power shell interface. Windows redirects you to the bash shell, and a new line opens up in the terminal window. This indicates that the environment has changed from Windows to BASH.

• Type sh yourfilename.sh inside the terminal window, where “yourfilename” is the name of the sh file, followed by file extensions.
• Through the same process, you will get to know how to run script file in Windows PowerShell.

2] Using Cygwin to run Shell Script files

The Official Cygwin application is a free and open-source command-line interface for Windows. With it, Linux and Unix programs can be compiled and run on Windows using a Linux-like interface similar to the original Linux BASH. Let us see how to run shell script in Linux from Windows through Cygwin:

• Head over to the official Cygwin website. Look for executable Windows files (setup-x86_64.exe) and download either the 32-bit or 64-bit version of Cygwin.
• Open the downloaded installation file from the Downloads folder, and follow the procedure as instructed by the on-screen steps. There are different options in the installation process, so make your choice accordingly.
• If you have installed the 64-bit version of Cygwin, open the Cygwin64 Terminal by double-clicking its shortcut on your desktop.

• The terminal will have access to any files on your pc, so provide the pathname (the folder where your script file is stored) in the following way: cd C:Users/Username/Desktop
• After you change the directory, it is time to execute shell scripts through the sh command: sh yourfilename.sh, where “yourfilename” is the name of the sh file, followed by file extensions.

3] Execute Shell Script using the Git command line for Windows

Git is a distributed version control system tool that is free and open-source, and it is available for use on all operating systems. The usefulness of Git is given in detail below:

• Changes in any set of files can be tracked using Git, which is most commonly used to coordinate the efforts of multiple programmers who are working together on the source code during the development process. 
• Rapidity, data integrity, and support for non-linear distributed workflows are just some of its primary objectives (thousands of parallel branches running on different systems).

Linux and macOS computers come pre-installed with Git as a command-line tool, which is the default. However, you can also get it from the official website, which has versions for all operating systems. So let us see how to run shell script in Windows git bash:

• Head over to the Official Git version control page by opening your browser and copying the given link: Download from here
• Click on the Windows link to download the git command line for your Windows platform.

• Go to the Downloads folder and open the setup file to start installing git. Go through the installation process by following the on-screen instructions, and make your choices accordingly.
• During the installation procedure, Git will install a context menu entry through which it becomes accessible to run shell script files from anywhere on the computer. Make sure to check that option in the installer.

• To run a script file, simply head over to the folder where the .sh file resides. Right-click on the folder name and select “GIT Bash Here.”
• The GIT command terminal known as the git bash appears, and the working location is already set to your script file folder.

• Run the script file using the command: sh filename.sh (The filename can be replaced with the original sh file name, followed by the file extensions)

4] Convert Script Shell files to Windows executable BAT files

This approach is not advised for typical users, but rather for those who are well-versed in the commands of scripts and batch files (bat files). For starters, we can simply update the format and extension of the SH file.

It does need the knowledge of how to translate a script file into a batch file, therefore you should avoid using this approach unless you are familiar with the formats of both of these files.

For the sample code modifications, we will demonstrate the straightforward procedures that must be followed.

• Batch files are simple scripted programs for Windows, and they are similar to Linux shell scripts. In Windows, a batch file can be executed by simply double-clicking on it.
• Firstly, we need to open a Linux sh script file using a text editor such as Notepad.
• Double-click on the sh file. When Windows says it can’t find a file to open it, click on More Options, and click on Notepad.

• The first line of the script file must be something like the one given below: #!/bin/bash
• Remove this shebang line from the code.
• If you are an expert script file coder, analyze the Linux codes used there and think of an alternative Windows version of the code to replace it with.
• Save the script file using Ctrl + S.

• Left-click on the Bash shell file, and press F2 to rename the file extensions. Modify the extension from .sh to .bat, press Enter and click Yes to confirm the changes.

• Open the Windows Run Window using the Win + R shortcut. Inside the search bar, type cmd to open the command prompt terminal.

• Change the directory to the folder path where the SH file is stored using cd folder name.

• Execute the translated batch file using the command filename.bat
• Do note that the commands that worked for Linux (such as comment notifier #) will not work for Windows, and might cause a syntax error when run. Therefore proper translation skill is important.

Are you interested in working with shell scripts on Windows? Thanks to a recent addition by Microsoft, you can now use Windows Subsystem for Linux to make this happen. 

Once you enable shell scripts in Windows 10, you can start creating shell scripts of your own. Shell scripts are great for automating simple tasks. You can also work on open-source Linux-based projects if that’s an area of interest to you. Finally, you’ll learn how to execute shell scripts on Windows 10. Continue reading to learn more.

What is Linux?

Linux is an open-source operating system that is highly popular among computer enthusiasts. Linux competes with other computer operating systems like Microsoft’s Windows, Apple’s macOS, and mobile operating systems like Android and iOS. 

The Linux operating system was originally developed by Linus Torvalds back in 1991. The Linux kernel was designed as a Unix-like operating system. Unix was an early operating system created by Bell Labs in 1969. Today, modern Linux distributions are still Unix-like, meaning they retain the basic structure and properties that Unix had. An example of a non-Unix operating system would be Microsoft Windows.

The top Linux distributions have changed over the years, but as of 2022, Ubuntu, Debian, CentOS, Fedora, and Red Hat rank as the top 5 most popular options. 

What is Bash?

When Linus Torvalds created Linux, he included a Unix shell called Bash. Bash had been created just two years before, in 1989 by Brian Fox. Bash has been the longtime default for Linux and was also the default for Apple macOS until it was replaced by Z shell in 2019. 

Until 2016, Windows users could not use the Linux kernel or Bash at all. Windows first introduced the Windows Subsystem for Linux (WSL) beta with Windows 10 version 1607 update. About a year later, in October 2017, WSL was fully released in Windows 10 version 1709. Microsoft developed WSL for hobbyists and developers who want to work on open-source Linux-based projects. 

It’s important to note that WSL is not preinstalled on Windows 10. If you would like access to create and run shell scripts on Windows 10, you will need to manually install WSL or join the Windows insider program. 

What is a shell script?

A Shell script is a type of script that cannot be run without a Unix shell. Further, a shell script is a series of commands that are executed line by line by the command line. 

You can use shell scripts to automate processes and avoid repetitive tasks. Instead of manually completing each step in a series, you can execute a script, and the command line will handle the rest.

For example, if you find yourself regularly stopping processes that are hogging your CPU, you can automate this process with a script. When you execute the script, it may be designed to find a set of processes using CPU resources and request to kill them. 

Enabling shell scripts in Windows 10

1. Click on the Start (Windows) button and enter “Control Panel” into the search bar. Click Open on the Control Panel result on the right-hand side.

1. Within the Control Panel window, find and click on Programs.

1. Now, from the Programs window, find Click Turn Windows features on or off underneath the Programs and Features header.

1. In the Windows Features window, scroll to the very bottom of the window. Check the Windows Subsystem for Linux option. Then click OK.

1. Windows will automatically install the necessary files. When the installation is complete, select Restart Now.

1. When your computer restarts, you need to install Ubuntu from the Microsoft store.

1. After installation, make sure you open Ubuntu and see it up. You are now ready to use scripts on your Windows 10 machine.

If you encounter any issues with Ubuntu or bash commands not working correctly, you may want to check that Virtualization is turned on in your BIOS. The most updated WSL version, WSL 2, runs the Linux kernel using virtualization technology. This means a virtual machine needs to be able to run on your system.

Now that Windows Subsystem for Linux and Ubuntu has been installed, you are ready to start creating shell scripts in Windows 10. You may be tempted to write bash scripts with Notepad, but this is not recommended. Because Notepad is designed for Windows/DOS systems, the line endings will differ from those that are found at the end of Unix/Linux line endings. 

Text editors for shell scripts

You should use software that is designed to convert to Unix/OSX end-of-line characters. The best open-source software available for this is Notepad++. Amazingly, Notepad++ is lovingly maintained and developed by a single individual, Don Ho. 

If you try Notepad++ and don’t like it, you can try another fan favorite, nano. Nano is a text editor for Unix/Linux systems. You can easily create shell scripts that will run in bash, using nano. Download nano to get started.

Example shell scripts

Let’s look at some basic shell scripts, so you can learn more about what you are going to be coding and see how some formatting and syntax work.

1. Hello World!

echo "Hello World!"

This script will print out the infamous Hello World! Notice that echo can be used as a print command when not combined with any other modifiers. It will print the string on a new line. If you add the -n modifier, the output will print on the same line. 

2. Sum two numbers

If you want to do some basic arithmetic, you might have a script that looks like:

# Add two numbers together
((sum=25+35))

# Print the sum of the numbers
echo $sum

Note that the # symbol is used to make comments that are not expressed. The output of this script will print the sum of 25+35, which is 60. 

3. Take user input

The following script will ask for the user’s name and then use the read command to take the user’s input. Then the user’s name is passed into the following expression, ultimately welcoming you to Windows Subsystem for Linux. 

echo "What is your name?"
read name
echo "Welcome $name to Windows Subsystem for Linux."

Write basic shell scripts in Windows 10

Continue reading to learn how to write basic shell scripts in Windows 10 using Notepad++.

1. Click the Start button and search for “Notepad++” and click Run as administrator on the right-hand side.

1. Now you can create your script.

1. Once your script is complete, you need to use the EOL Conversion option available in Notepad++. Click Edit and locate EOL Conversion from the dropdown menu. Hover over this option and then select UNIX/OSX Format from the next dropdown menu.

1. Now select File and then Save As. Make sure to name your file something you will recognize and add .sh to make it a shell script file.

1. Once the shell script is saved, continue to the next section to learn how to run your own shell scripts.

How to run shell scripts (.sh files) on Windows 10

You’ve created your first shell scripts, and it’s time to execute the sh file. Remember that when using WSL, you can only use Linux commands and utilities. Windows 10 programs will not work in bash scripts. To execute a script file, follow these step-by-step instructions:

1. Click on the Start (Windows) button and enter “Command Prompt” into the search bar. Click Run as administrator on the Command Prompt result on the right-hand side.
2. Navigate to the folder where the script file is saved. You move around in the command prompt using the cd command. For example, if you want to access the Documents folder, you would enter the following and press Enter:

   cd C:\Users\Username\OneDrive\Documents

   Note: Username would be the username that you set up for yourself when you registered your computer. 

1. Now enter bash file-name.sh, where file-name is the whatever you’ve named your script file. 

   bash file-name.sh

   The script will execute, and if there are any outputs or print statements included in the script, the output will be returned.

Bash scripts running on Windows 10

You’ve made it far and learned a ton of information in one go. Command-line utilities, different operating systems, and learning to write and execute shell scripts can be difficult topics. In fact, these topics will take time to master. You have a ton of learning to do for scripting, but resources are available to help you all over the internet. 

Within this guide, you learned the basics of Linux and Bash. You learned what shell scripts are and that you need to specifically enable Windows Subsystem for Linux (WSL) to use them. You learned how to create shell scripts using Notepad++ and how to execute the scripts in bash. Enjoy experimenting!

If you have worked with Linux distributions and repositories, you would know what shell scripts are. To run shell scripts on top of a Windows computer can be challenging, as the process is not quite straightforward.

Shell scripts are a piece of code written in plain text but have the “.SH” file extension. These are usually used to automate tasks and execute Linux or Unix packages. These are written in Bash and start with “#! /bin/sh“.

You do not need to install a Linux or Unix distribution alongside your Windows operating system to run a shell script. In this article, we’ll show you how to run a shell script on a Windows PC.

What are Shell (.SH) Files

The Linux/Unix operating system uses shell or .SH script files to perform certain tasks. In comparison, it can be substituted by Windows batch files for the Windows operating systems, which are used to execute commands on a computer.

The Batch language is a simple and interpreted programming language, unlike C++ or C#. However, you do not have to translate a shell script file to batch to perform similar tasks on a Windows computer, as you do on a Linux PC.

There are different methods to run the same .SH file on a Windows computer as on a Linux system. Let us show you how to run a shell file on a Windows PC.

Run Shell Script (.SH) File on Windows

There are both native and third-party methods to run shell files on a Windows computer. You can use Cygwin, or a third-party tool of your choice, to run a shell script on Windows OS. Alternatively, you can install the Windows Subsystem for Linux feature on Windows and then execute the shell script file through it.

Below you’ll find the methods to run the file using both methods.

Run Shell Script File using Windows Subsystem for Linux (WSL)

This section has been divided into 3 steps to make the process easier to understand. You must do the following 3 things to run a shell script file in the given order:

1. Install WSL
2. Install a Linux distro
3. Run the shell script file

Note: If you are performing these steps on a Virtual Machine, then you will need to enable Nested Virtualization.

Install WSL

Use the following steps to install WSL on your computer:

1. Press the Windows Key + R shortcut keys to open the Run Command box.

2. Type in “optionalfeatures” and press Enter.

   

3. Select “Windows Subsystem for Linux” and “Virtual Machine Platform,” and then click Ok.

   

   The wizard will now install WSL.

4. When the installation is completed, click “Restart now.”

   

Once the computer restarts, it is time to install a Linux distro.

Install a Linux Distribution

Use the following steps to install a Linux distribution:

1. When it restarts, press Windows Key + R again to open Run.

2. Type in “cmd” and press CTRL + Shift + Enter to run Command Prompt as administrator.

3. Run the following command to obtain a list of available Linux distros:

   wsl --list --online

   

   Note down the name of the distro you want to install.

4. Use the following command to install the preferred distro while substituting its name:

   wsl --install -d [DistributionName]

   

   The distro will now begin to download and install.

5. Set up a username and password.

   

6. Restart the computer.

Now, the next step is to simply run the shell script file.

Run the Shell Script File

Follow the simple steps below to run the shell script file on a Windows PC:

1. Press the Windows Key + R again to open Run.

2. Type in “cmd” and press CTRL + Shift + Enter to run Command Prompt as administrator.

3. Use the CD cmdlet to change the directory to the location of the shell script file.

   CD [PathToShellScriptFile]

   

4. Now, use the following command to run the shell script file while substituting [ShellFileName] with the complete and correct name of the shell file:

   Bash [ShellFileName].sh

   

This is how you run a shell script (.SH) file on a Windows computer using WSL.

If this seems like a lengthy process for you, then you can also use the alternative method given below.

Run Shell Script File using Third-Party Tools

You can also run a shell script file on a Windows computer using a third-party tool. In the steps below, we have used Cygwin.

Follow these steps to run a .SH file on a Windows PC:

1. First, download and install Cygwin from their official website.

2. Once installed, run the Cygwin app.

3. In the Cygwin terminal, use the CD command to change the directory to the shell script file location.

   Note: In Cygwin, the syntax to change the directory is different from Command Prompt or PowerShell. Use the following command syntax and example in the image to change your directory in Cygwin.

   CD /cygdrive/[driveLetter]/[Subfolder1]/[Subfolder2]

   

4. Now, make the shell script file executable through this command:

   chmod +x [ShellFileName].sh

   

5. Now, use the following syntax to run the shell script file:

   ./[ShellFileName].sh

   

These are the two methods to run shell script files (.SH) on a Windows PC. Of course, there are many other third-party tools available that allow you to run Linux and Unix files on a Windows computer.
