bash.exe: The GNU Bourne Again Shell in Windows
Introduction
bash.exe is the executable file for the Bash (Bourne Again Shell) shell, a command-line interpreter widely used in Linux and Unix-like operating systems. Its presence on a Windows system isn’t inherently part of the standard Windows installation. It typically arrives through one of several avenues:
- Windows Subsystem for Linux (WSL): This is the most common way
bash.exeends up on a Windows machine. WSL allows users to run a genuine Linux distribution (like Ubuntu, Debian, or OpenSUSE) directly within Windows, without the need for a separate virtual machine.bash.exein this context is the primary interface to that Linux environment. - Git for Windows: The popular version control system, Git, often includes a bundled version of Bash. This is commonly found in a directory like
C:\Program Files\Git\bin\bash.exeorC:\Program Files\Git\usr\bin\bash.exe. This version is specifically tailored to provide a consistent Git experience across different operating systems, and while it offers many Bash commands, it’s not a full Linux environment. - Cygwin: Cygwin is a large collection of GNU and Open Source tools which provide functionality similar to a Linux distribution on Windows.
bash.exeis a core component of Cygwin. - MinGW/MSYS2: MinGW (Minimalist GNU for Windows) and MSYS2 (Minimal SYStem 2) are environments that provide a minimal Unix-like shell and tools for Windows, primarily used for software development. They include
bash.exe. - Other Third-party Tools: Some other third-party software also provide
bash.exe
The specific capabilities and behavior of bash.exe depend heavily on which of these methods brought it to your system.
Origin and Purpose
Bash, written by Brian Fox for the GNU Project, is a powerful command-line interpreter and scripting language. It’s the default shell on most Linux distributions and macOS (prior to Catalina, which switched to Zsh). Its primary purposes are:
- Command Execution: Running programs and utilities by typing their names (and arguments) at the command line.
- File Management: Navigating directories, creating, deleting, copying, and moving files.
- System Administration: Managing users, processes, and system settings.
- Scripting: Writing scripts (sequences of commands) to automate tasks. Bash scripts are essentially small programs that the shell interprets.
- Piping and Redirection: Connecting the output of one command to the input of another (
|, piping), and redirecting input and output to/from files (<,>,>>). - Environment Variables: Managing variables that control the behavior of the shell and other programs.
Is bash.exe a Virus?
No, bash.exe itself is not a virus. It’s a legitimate and widely used program. However, like any executable, it can be used maliciously. Here’s the breakdown:
- Legitimate
bash.exe: Ifbash.exeis part of WSL, Git for Windows, Cygwin, or MinGW/MSYS2 (and you installed these tools knowingly), it is almost certainly safe. These are reputable projects, and their installers are generally trustworthy. - Potential for Misuse: Because Bash is a powerful scripting language, a malicious script executed through
bash.execould harm your system. This is notbash.exebeing a virus, but ratherbash.exebeing used to run a malicious script. This is analogous to howpowershell.exeorcmd.execan be used to run harmful scripts. - Unexplained
bash.exe: If you findbash.exeon your system and you did not knowingly install WSL, Git, Cygwin, or MinGW/MSYS2, then it could be a sign of malware. Some malware might bundle a copy of Bash to execute its scripts. This is relatively rare, but it’s a possibility. If you’re unsure, investigate the file’s location and properties, and run a virus scan.
In short: bash.exe is not inherently dangerous, but it’s a tool that can be used for harmful purposes if a malicious script is run through it, or if it’s placed on your system by unexpected, malicious software.
Will bash.exe Become a Virus?
bash.exe itself cannot «become» a virus. Executables are static files; they don’t change their nature spontaneously. The risk lies in:
- Malicious Scripts: The primary threat is running a Bash script that contains malicious code.
- Vulnerabilities: Extremely rarely, a vulnerability might be discovered in Bash itself that could be exploited. However, these are usually patched quickly by the respective maintainers (WSL, Git, Cygwin, etc.).
Usage (Focusing on WSL)
Since WSL is the most common way to have a fully functional bash.exe on Windows, we’ll focus on its usage within that context.
Accessing Bash (WSL):
-
Install WSL: If you don’t have WSL installed, you’ll need to enable it. Open PowerShell as an administrator and run:
powershell
wsl --install
This will install the default Linux distribution (usually Ubuntu). You can choose a different distribution usingwsl --list --onlineandwsl --install -d <DistroName>. You’ll be prompted to create a Linux user account and password. -
Launch Bash: Once WSL is installed, you can launch Bash in several ways:
- From the Start Menu: Search for «Ubuntu» (or your chosen distribution) and click the icon.
- From the Command Prompt or PowerShell: Type
bashorwsland press Enter. - From Windows Terminal: (Recommended) Windows Terminal is a modern terminal application that supports multiple shells, including Bash (WSL).
Basic Bash Commands:
Here’s a small sample of commonly used Bash commands:
ls: List files and directories.ls -l: Long listing (shows permissions, owner, size, date).ls -a: Show all files, including hidden ones (those starting with a dot).ls -lh: Long listing with human-readable file sizes (e.g., 1K, 234M, 2G).
cd: Change directory.cd /: Go to the root directory.cd ~: Go to your home directory.cd ..: Go up one directory level.cd /path/to/directory: Go to a specific directory.
pwd: Print working directory (shows your current location).mkdir: Make directory.mkdir my_new_directory
rmdir: Remove directory (only works if the directory is empty).rm: Remove files (and directories, with options).rm myfile.txtrm -r my_directory: Recursively remove a directory and its contents (BE CAREFUL!).rm -rf my_directory: Recursively remove a directory and its contents, forcefully (without prompting — EXTREME CAUTION!).
cp: Copy files and directories.cp file1.txt file2.txt: Copyfile1.txttofile2.txt.cp -r dir1 dir2: Recursively copy directorydir1todir2.
mv: Move or rename files and directories.mv file1.txt file2.txt: Renamefile1.txttofile2.txt.mv file1.txt /path/to/new/location/: Movefile1.txtto another directory.
cat: Concatenate and display file contents.cat myfile.txt
echo: Print text to the terminal.echo "Hello, World!"
touch: Create an empty file or update the timestamp of an existing file.touch newfile.txt
grep: Search for patterns in files.grep "pattern" myfile.txt: Search for «pattern» inmyfile.txt.grep -i "pattern" myfile.txt: Case-insensitive search.grep -r "pattern" my_directory: Recursively search in a directory.
man: Display the manual page for a command.man ls(Shows the manual for thelscommand).
sudo: Execute a command with superuser (administrator) privileges. (Requires your Linux user password in WSL).sudo apt update(Updates the package list in Ubuntu/Debian).
apt(Ubuntu/Debian): Package manager for installing, updating, and removing software.sudo apt update: Refreshes the list of available packages.sudo apt upgrade: Upgrades installed packages.sudo apt install <package_name>: Installs a package.sudo apt remove <package_name>: Removes a package.
- Piping (
|): Connects the output of one command to the input of another.ls -l | grep ".txt": Lists files and then filters the output to show only lines containing «.txt».
- Redirection (
>,>>,<):ls -l > filelist.txt: Redirects the output ofls -lto a file namedfilelist.txt(overwrites if it exists).ls -l >> filelist.txt: Appends the output ofls -ltofilelist.txt.sort < filelist.txt: Sorts the contents offilelist.txt(reads from the file).
Accessing Windows Files from WSL:
WSL automatically mounts your Windows drives under /mnt/. For example:
- Your C: drive is usually accessible at
/mnt/c/. - Your D: drive is usually accessible at
/mnt/d/.
You can navigate to your Windows files using the cd command:
cd /mnt/c/Users/YourWindowsUsername/Documents
Accessing WSL Files from Windows:
You can access the WSL filesystem from Windows Explorer using the path:
(Replace <DistroName> with the name of your distribution, e.g., Ubuntu-20.04). It’s recommended to use this method instead of directly modifying files within the WSL filesystem from Windows, as direct modification can sometimes cause issues.
Running Windows Executables from WSL:
You can run Windows executables (.exe files) directly from within WSL. Just type the full path to the executable:
/mnt/c/Windows/System32/notepad.exe
Or, more concisely, if the executable is in your Windows PATH:
Conclusion
bash.exe on Windows, most commonly through WSL, provides a powerful Linux-like environment within Windows. It’s a legitimate and valuable tool for developers, system administrators, and anyone who prefers a Unix-style command-line interface. While not a virus itself, it’s crucial to be aware of the potential for malicious scripts to be executed through Bash, just as with any other command-line interpreter. Understanding its origin and purpose, and practicing safe scripting habits, are essential for using bash.exe effectively and securely.
Недавно мы говорили о том, как выполнять различные Linux утилиты в Windows. Но для Windows 10 это, похоже, уже неактуально. Уже давно в Windows 10 появилась нативная поддержка оболочки Bash, в окружении дистрибутива Ubuntu благодаря подсистеме Linux для Windows 10.
Вы можете запускать различные дистрибутивы Linux в Windows без виртуализации, а с недавних пор, можно даже полноценно заставить работать графический интерфейс, правда для этого уже нужна вторая версия WSL. В этой статье мы рассмотрим как установить Linux в Windows 10.

Что такое WSL?
В начале цикла разработки Windows 10, Microsoft открыла страницу обсуждения и голосования за новые функции. Там зашел разговор о командной строке Windows. Разработчики спросили сообщество, что им не нравится в командной строке Windows и какие функции они хотели бы увидеть в новой версии.
Многие пользователи заявили что им нужны небольшие улучшения командной строки, другие же сказали что неплохо было бы иметь возможность использовать инструменты Linux / Unix и Bash в Windows 10. Много пользователей согласились с тем, что нужно сделать проще использование этих инструментов в Windows.
Прислушиваясь к голосу сообщества, в Microsoft первым делом улучшили CMD, PowerShell и другие инструменты командной строки. А во-вторых, они сделали, то что казалось невероятным несколько лет назад, они добавили реальный, нативный Bash вместе с поддержкой всех необходимых инструментов командной строки, работающих непосредственно на Windows, в среде, которая ведет себя как Linux. Это не какая-нибудь виртуальная машина, это реальный Linux в Windows.
Для реализации этого Microsoft построили новую инфраструктуру в Windows, это Windows Subsystem for Linux или WSL, на основе которой работает образ окружения Ubuntu, поставляемый партнером Canonical. Эта функция позволит разработчикам более эффективно использовать инструменты Linux. Инфраструктура основана на уже заброшенном проекте, Project Astoria, который должен был использоваться для запуска Android-приложений в Windows. Ее можно расценивать как противоположность Wine, только Wine запускает приложения Windows в Linux, подсистема Linux позволяет выполнять приложения Linux в Windows, точнее, только консольные приложения Bash в Windows 10.
С технической точки зрения, это вообще не Линукс. Каждая система GNU Linux должна быть основана на ядре Linux, здесь же просто есть возможность выполнять двоичные файлы, которые работают в Ubuntu.
С каждой новой версией в WSL всё меньше ограничений, вы уже можете использовать сервисы, а также с WSL 2 стали доступны графические приложения. Решение предназначено для разработчиков, которые хотят запускать linux-утилиты из командной строки Windows. Да, эти команды имеют доступ к файловой системе Windows, но вы не можете использовать их для автоматизации своих задач или в стандартной командной строке Windows. Теперь давайте разберемся как установить WSL в Windows 10.
1. Проверка версии системы
Вы можете установить WSL в Windows 10 начиная с версии Windows 10 Insider Preview 14316, а для WSL версии 2, которая принесла много улучшений нужно обновление Windows 10 19041 или новее. Сначала убедитесь, что у вас правильная версия Windows. Для этого октройте PowerShell кликнув правой кнопкой по иконке пуск:
Затем выполните команду:
[environment]::osversion
Если отображается версия как на снимке экрана или выше, значит всё хорошо. Иначе идите обновлять систему.
2. Активация WSL и виртуализации
Чтобы активировать компонент Windows Subsystem for Linux можно использовать уже открытую командную строку PowerShell. Для этого выполните:
dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
Затем выполните ещё одну команду чтобы включить компонент виртуализации Hyper-V:
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart
Когда эта работа будет выполнена перезапустите компьютер, чтобы все компоненты установились.
3. Активация WSL 2
Чтобы установить WSL 2 необходимо скачать пакет с новым ядром с официального сайта Microsoft. Кликните по ссылке download the latest WSL2 Linux kernel:
Затем установите загруженный файл:
Чтобы всегда по умолчанию использовалась версия WSL 2 необходимо выполнить такую команду:
wsl --set-default-version 2
Если вы всё же получаете ошибку, с сообщением о том, что такой опции у этой команды нет, значит у вас старая версия Windows, обновляйте. Если команда не выдала ошибки — значит настройка WSL завершена успешно.
4. Установка Linux
Далее вам надо установить какой-либо дистрибутив Linux из магазина Microsoft. Достаточно просто открыть магазин и набарть в поиске имя дистрибутива, например Ubuntu, затем нажмите кнопку Get:
Дождитесь завершения установки и запустите загруженный дистрибутив из главного меню:
5. Настройка дистрибутива
При первом запуске будет выполняться настройка окружения. Вам необходимо указать имя пользователя:
Затем два раза пароль:
После этого вы сможете пользоваться оболочкой Bash в Windows 10:
6. Установка X сервера
Если вы хотите запускать графические приложения из WSL Windows, то вам понадобится установить в систему X сервер. Скачать его можно здесь.
Затем просто установите.
7. Запуск X сервера
После завершения установки на рабочем столе появится ярлык. В первом окне выберите Multipe windows чтобы окна программ, выполняемых на X сервере интегрировались в систему:
Затем выберите, что клиентов запускать не надо — Start no client:
Поставьте все галочки, затем нажмите кнопку Next, а потом Finish для завершения установки.
Брандмауэр Windows тоже попросит разрешить доступ этому приложению в сеть. Надо разрешить.
8. Настройка подключения
Чтобы настроить подключение к X серверу из WSL нужно узнать какой адрес система Windows присвоила WSL окружению, для этого вернитесь к PowerShell и выполните:
ipconfig
В данном случае это 172.25.224.1. Выполните в окружении дистрибутива такую команду:
export DISPLAY=172.25.224.1:0
Шаг 9. Установка и запуск приложений
Для установки приложений в дистрибутив необходимо сначала обновить списки репозиториев:
sudo apt update
Затем установите графическое приложение, например, Firefox:
sudo apt install firefox
После этого его можно запустить:
firefox
На снимке вы видите графический интерфейс WSL для браузера Firefox, запущенного в Linux:
Использование WSL
Установка WSL Windows 10 завершена. Теперь у вас есть полноценная командная строка Ubuntu в Windows с оболочкой Bash. Поскольку используются одни и те же двоичные файлы, вы можете устанавливать программное обеспечение с помощью apt из репозиториев Ubuntu. Можно установить любое приложение, но не все будут работать.
Если вы раньше уже пользовались Bash в Linux или MacOS, то будете чувствовать себя здесь как дома. Здесь не нужно использовать команду sudo, поскольку у оболочки уже есть права администратора. Ваша файловая система Windows доступна в /mnt/c.
Для управления и перемещения по каталогам используйте те же команды что и в Linux. Если вы привыкли к стандартной оболочке Windows, то вот основные команды, которые вам могут понадобится:
- cd — изменить текущий каталог;
- ls — посмотреть содержимое каталога;
- mv — переместить или переименовать файл;
- cp — скопировать файл;
- rm — удалить файл;
- mkdir — создать папку;
- vi или nano — открыть файл для редактирования.
Важно также понимать, что в отличии от WIndows, оболочка Bash и ее окружение чувствительны к регистру. Другими словами, file.txt и File.txt, это совсем разные файлы.
Для установки и обновления программ необходимо использовать команду apt-get. Вот небольшой список ее параметров:
- apt update — скачать списки программного обеспечения из репозиториев;
- apt install пакет — установить пакет;
- apt search слово — поиск пакета по слову;
- apt upgrade — загрузка и установка последних обновлений дистрибутива.
Не забудьте, что устанавливаемые в этой оболочке программы, ограничиваются по области действия оболочкой. Вы не можете получить доступ к ним из обычной командной строки PowerShell, CMD или в любом другом месте Windows. Также WSL не может напрямую взаимодействовать с исполняемыми файлами Windows, хотя обе среды имеют доступ к одним и тем же файлам на компьютере.
Выводы
Использование Linux в Windows как нельзя лучше подойдёт для разработчиков, но может понадобиться и начинающим пользователям, которые хотят познакомиться с системой. А что вы обо всём этом думаете? Использовали ли когда-нибудь WSL? Напишите в комментариях!
Archival Notice
I’ve decided to archive this project. I have no intention of developing it any farther now that I am in college.
I no longer have the time nor the want to continue work on it. It served an instrumental role in my learning
how to work with strings, file systems, and operating systems.
Bash for Windows
This is a project written in Python that I have been working on off and on over the years. Bash for Windows
attempts to recreate a Bash-like environment that can work on Windows, that being versions of Windows
that isn’t compatible with WSL or for people that don’t want to use WSL.
Installation
In the GitHub Page, go to the Releases tab and download the latest zip of the install files. Unzip that file
and run the Setup.exe file. There is also a Readme file in that zip file which will help guide you through the
Installation process.
Uninstallation
Bash for Windows does not leave anything in the Windows Registry or deep in the file system. To remove Bash
for Windows from your system, simply remove the Bash for Windows folder that you chose to install Bash for
Windows into, and it will be off your system.

When Microsoft’s CEO announced that the Bash shell was coming to Windows, several people couldn’t believe it. #BashOnWindows trended on Twitter for days; such was the impact of this news.
Initially referred as Bash on Windows, it is actually called Windows Subsystem for Linux, popularly known as WSL.
With WSL, you can install one of the supported Linux distribution inside Windows and use the Windows terminal to access the Linux systems and run Linux commands.
In this tutorial, you’ll learn how to enable WSL on Windows and then install a Linux distribution of your choice.
📋
This tutorial was tested with the latest Windows 11 version 22H2, and build 22621.819. You might need to update your Windows installation if you have an older build to follow everything in this tutorial.
What is WSL?
WSL (formerly Bash on Windows) provides a Windows subsystem, and Linux runs atop it. It is not a virtual machine or an application like Cygwin. It is a complete Linux system inside Windows 10/11. It allows you to run the same Bash shell you find on Linux. You can run Linux commands inside Windows without installing a virtual machine or dual-boot Linux and Windows.
You install Linux inside Windows like a regular application. This is a good option if your main aim is to learn Linux/UNIX commands.
Check for System Compatibility
You must be running specific versions of Windows for the different features described in this article. Requirements necessary for a particular feature to work are described under its titles. To check your Windows version, search for about in the start menu.
Here, you can see the build of your PC, as shown in the screenshot below. Make sure it is matching with the respective requirements described under various sub-headings here in this article.
- You must be running Windows 10 version 1607 (the Anniversary update) or above.
- WSL only runs on 64-bit versions 32-bit versions are not supported.
Install Bash in Newer Windows 10 and 11
The good thing is that the latest set of upgrades, including the stable release of WSL v1.0 released from Windows, makes it easier to install Bash on Windows.
There are two ways you can go about it:
- You can get it in one click from Windows Store.
- Choose to use the command-line.
1. Install WSL Using the Microsoft Store
Launch the Microsoft Store and search for «Windows subsystem«.
Install it, and you’re done with the first step. Next, you have to install a Linux distribution.
So, if you try to open WSL, you will get to see a window informing you that no distribution is installed.
Similar to WSL, search for the distribution on Microsoft Store, and then install it.
For instance, I installed Ubuntu from the store as shown in the image below:
And, then proceed to «Open» it and it will automatically start installing. The procedure is same for any distribution you choose.
We then have to configure it, which is discussed right after installing it through the command line.
2. Install WSL and the default distribution using the command-line
In WSL, the default distribution is Ubuntu (which can be changed). To install, open Powershell as an administrator.
For this, search for Powershell in the start menu, right-click on Powershell and select Run as Administrator.
Inside Powershell, enter the following command to install WSL, along with all necessary features and the default distribution, that is, Ubuntu.
wsl --installOnce finished downloading and installing, you need to reboot to apply the changes.
Whether you installed WSL and Ubuntu using the Microsoft Store or the command line, you need to configure it.
Here’s how it is done:
🛠️ Configure the newly installed Ubuntu
After rebooting, search for Ubuntu in Start Menu and open it.
It will ask you to enter a UNIX Username and Password. Enter these details and press enter key.
You will now be inside the terminal window of Ubuntu.
Once logged in, you need to update the installed Ubuntu. For this, enter the following commands one by one:
sudo apt update
sudo apt full-upgradeAfter completing the update, you are good to go with Ubuntu in WSL.
Install Bash on Older Windows
If you have the minimum requirements mentioned in the beginning but are running an older Windows build, the previous method may not be supported. So there is a manual installation method.
Also, there are both WSL1 and WSL2 available. WSL2 offers some upgraded functionalities but has some minimum requirements to run:
- For x64 systems: Version 1903 or later, with Build 18362 or later.
- For ARM64 systems: Version 2004 or later, with Build 19041 or later.
So this brings us to two possibilities to install:
- Install Ubuntu with WSL1
- Install Ubuntu with WSL2
1. Install Ubuntu with WSL 1
This is a relatively simple procedure for those with a system incompatible with WSL2. First, you need to enable the Windows Subsystem for the Linux feature. This can be done through the command line. Open Powershell as an administrator and enter the following command:
dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestartOr, to do this via GUI, follow the steps below:
- Search for Windows Features in Start Menu.
- Turn on Windows Subsystem for the Linux feature.
- Reboot your system.
- Open the Windows store and search for the distribution of your choice to install.
Once installation is completed, open the Ubuntu app from the start menu. It will take a couple of seconds to install. You will be prompted to enter a username and password. Provide those credentials, and you are good to go with Ubuntu in WSL1.
2. Install Ubuntu with WSL 2
It is recommended to use WSL2 instead of WSL1 if you have support. To install Ubuntu with WSL2, you need to make sure that the Windows Subsystem for Linux feature is turned on. For this, as in the above case, execute the following command in an elevated Powershell:
dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestartReboot the device once the command is completed.
After this, you need to enable the Virtual Machine Platform feature. Open the Powershell with admin privileges and enter the following command:
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestartOnce again, restart the device to complete the WSL install and update to WSL 2.
Now, download the Linux Kernel Update Package for x64 machines from the official website. If you are using ARM64 devices, use this link to download the latest kernel update package.
If you are not sure about the device architecture, enter the command below in Powershell to get the type:
systeminfo | find "System Type"When the file is downloaded, double-click on it and finish the installation of the Kernel update package.
Now, open PowerShell and run this command to set WSL 2 as the default version when installing a new Linux distribution:
wsl --set-default-version 2Once WSL2 is set as the default version, you can now install the Linux distribution of your choice.
Go to Windows Store and install Ubuntu, as described in the earlier steps. and the rest of the procedure is already described above.
Enjoy Linux inside Windows.
🔧 Troubleshooting Tip 1
«The WSL optional component is not enabled. Please enable it and try again.»
You may see an error like this when you try to run Linux inside Windows 10:
The WSL optional component is not enabled. Please enable it and try again.
See https://aka.ms/wslinstall for details.
Error: 0x8007007e
Press any key to continue...And when you press any key, the application closes immediately.
The reason here is that the Windows Subsystem for Linux is not enabled in your case. You should enable it as explained in this guide. You can do that even after you have installed Linux.
🔧 Troubleshooting Tip 2
Installation failed with error 0x80070003
This is because Windows Subsystem for Linux only runs on the system drive i.e. the C drive. You should ensure that when you download Linux from the Windows Store, it is stored and installed in the C Drive.
On Windows 10, go to Settings -> Storage -> More Storage Settings -> Where new content is saved: Change where new content is saved and select C Drive here.
On Windows 11, go to Settings -> System -> Storage -> Advanced storage settings -> Where new content is saved and select C Drive here.
🔧 Troubleshooting Tip 3
«Failed to attach disk Error»
Sometimes, this error will appear when we reinstall the Ubuntu in WSL.
In this case, open Powershell and run the following command:
wsl -l -vThis will list the installed Linux systems. Find the name of the system, that is throwing the error, in my case Ubuntu. Now run the following command:
wsl --unregister UbuntuYou can restart the ubuntu app and it will run without any issues.
You can refer to more common troubleshooting methods from the official website.
Run GUI Apps On Windows Subsystem for Linux
The ability to run GUI apps on Windows Subsystem for Linux was introduced with the WSL 2 release in May 2020.
Windows Subsystem for Linux (WSL) with WSL2 now supports running Linux GUI applications (X11 and Wayland) on Windows in a fully integrated desktop experience. This allows you to install Linux applications and seamlessly integrate them into Windows desktop, including features like “pin to taskbar”.
📋
One crucial point is that you must be on Windows 10 Build 19044+ or Windows 11 to access this feature.
Step 1: Enable/Update WSL 2
This procedure has been explained in the above section and you can refer to it.
Step 2: Download and Install Graphics drivers
To run GUI apps, you need to install appropriate graphics drivers. You can use the following link to download the drivers according to your provider.
- Intel GPU Driver for WSL
- AMD GPU Driver for WSL
- NVIDIA GPU Driver for WSL
Once installed, you are all done.
Step 3: Install some GUI Apps
Now, go to your Ubuntu app and install any GUI app using the APT package manager. You should note that running apps from other sources like flatpak are problematic within WSL.
For this article, I installed the Gedit text editor using the following command:
sudo apt install gedit -yThis will install several MB of packages including required libraries. Once completed, you can run the following command to start the GUI Gedit app in Windows.:
gedit
Similarly, you can install all the popular applications available to Linux, including Nautilus file manager, GIMP, etc. For more about running GUI applications in WSL, you can refer to the official documentation.
Install Linux Bash Shell on other older Windows 10
If you cannot get the Fall Creator’s update on Windows 10 for some reason, you can still install it if you have the Anniversary update of Windows 10. But here, you’ll have to enable developer mode. I still recommend upgrading to the Fall Creator’s update or the latest Windows 10 2004 version update though.
Press Windows Key + I to access Windows system settings. Here, go to Update & Security:
From the left side pane, choose “For developers.” You’ll see an option for “Developer mode.” Enable it.
Now search for Control Panel and in Control Panel, click on “Programs”:
In Programs, click “Turn Windows features on or off”:
When you do this, you’ll see several Windows features. Look for “Windows Subsystem for Linux” and enable it.
You’ll need to restart the system after doing this.
After restarting the computer, click the start button and search for “bash”.
When you run it for the first time, you’ll be given the option to download and install Ubuntu. You’ll be asked to create a username and password during this process. It will install an entire Ubuntu Linux system, so have patience as it will take some time in downloading and installing Linux on Windows.
Once this is done, go back to the Start menu and search for Ubuntu or Bash.
Now you have a command line version of Ubuntu Linux. You can use apt to install various command line tools in it.
💬 I hope you find this tutorial helpful for installing bash on Windows and experimenting with Linux GUI apps on Windows. No wonder WSL lets you play with Linux inside of Windows. If you have questions or suggestions, feel free to ask.
Running a Bash script in Windows might seem daunting at first, especially if you’re accustomed to using different operating systems. However, with the right tools and guidance, you can easily execute your Bash scripts on a Windows environment. In this article, we will explore various methods to run Bash scripts on Windows, optimizing for those curious about run bash script windows. Let’s dive right in!
What is a Bash Script?
Bash scripts are files containing a series of commands executed in the Bash shell, which is a Unix-based command-line interface. These scripts are widely used in Linux systems for automating tasks, managing system operations, and leveraging powerful features available in the Bash environment. The flexibility of Bash scripts allows for executing complex tasks with simple instructions.
Why Use Bash Scripts on Windows?
Although Windows has its own scripting capabilities via PowerShell and batch files, many developers and system administrators prefer Bash for various reasons:
- Familiarity: Many experienced developers utilize Linux or Unix systems
- Compatibility: Bash scripts can often be ported between platforms with minimal modifications
- Rich toolset: Bash has a broad suite of built-in commands and third-party tools
Ways to Run Bash Scripts on Windows
There are several methods to run Bash scripts on Windows, each suited to different user preferences and requirements:
1. Using Windows Subsystem for Linux (WSL)
Windows Subsystem for Linux (WSL) allows you to run a Linux distribution alongside your Windows operating system. This is one of the most popular methods for running Bash scripts on Windows.
Steps to Enable WSL:
- Open the Windows PowerShell as an administrator.
- Run the command:
wsl --install
- Restart your computer to apply the changes.
Downloading a Linux Distribution:
After enabling WSL, you can choose a Linux distribution from the Microsoft Store (e.g., Ubuntu, Debian). Once installed, you can open it just like any other application.
Running Your Bash Script:
- Open your chosen Linux distribution from the Start menu.
- Navigate to the directory containing your script using the cd command.
- To run the Bash script, use:
bash script_name.sh
2. Using Git Bash
Git Bash is a package that installs a Bash emulation environment on Windows, which is particularly helpful for Git version control. Here’s how to install and use Git Bash:
Installing Git Bash:
- Download the Git installer from the Git Official Site.
- Run the installer and follow the prompts to complete the installation.
Running Your Script in Git Bash:
- Open Git Bash from the Start menu.
- Use the cd command to navigate to your script’s directory.
- Execute the Bash script with:
bash script_name.sh
3. Using Cygwin
Cygwin provides a large collection of GNU and Open Source tools which provide functionality similar to a Linux distribution on Windows. Follow these steps to install and use it:
Installing Cygwin:
- Download the Cygwin setup executable from the Cygwin website.
- Run the installer and select the packages needed for your Bash scripts.
Running Your Script with Cygwin:
- Launch Cygwin from the Start menu.
- Change to your script’s directory using the cd command.
- Run your script:
bash script_name.sh
Best Practices for Writing Bash Scripts
When creating Bash scripts to run on Windows or any platform, consider the following best practices to enhance readability and functionality:
- Use Descriptive Names: Name your scripts descriptively to reflect their purpose.
- Document Your Code: Comment your script to explain complex parts or functions.
- Make Your Script Executable: Use the command:
chmod +x script_name.sh
Test Thoroughly: Always test your scripts in a controlled environment before deploying them.
Common Issues and Troubleshooting
Despite the simplicity of running Bash scripts on Windows, you may encounter some common issues:
1. Permission Denied Error
This error occurs when your script lacks execution privileges. Ensure you have made the script executable using the chmod command as mentioned above.
2. Line Endings Issues
Bash scripts created in Windows can have different line endings than those in Linux. To convert line endings, use:
dos2unix script_name.sh
3. Environment Variable Problems
If your script relies on certain environment variables, ensure they’re set correctly within your Bash environment. You can check your environment variables with:
printenv
Conclusion
Running a Bash script on Windows has become increasingly accessible with the introduction of tools like WSL, Git Bash, and Cygwin. Each method has its advantages, so choose the one that best fits your workflow and requirements. Always keep usability and compatibility in mind, as well as best practices for writing effective and efficient Bash scripts.
