3 The following slides to install, run, and manage Ubuntu on Windows is based on a more detail guide that can be found on howtogeek.com. Please visit the website and learn more about this exiting new (finally useful ) feature of Windows.!3

4 Ubuntu on Windows Install bash shell 4

5 Windows 10 s Anniversary Update offers a big new feature for developers: A full, Ubuntu-based Bash shell that can run Linux software directly on Windows. This is made possible by the new Windows Subsystem for Linux Microsoft is adding to Windows 10. Note: This only works on 64-bit builds of Windows 10!!! First open the Settings app and head to Update & Security > For Developers. Activate the Developer Mode switch here to enable Developer Mode. 5

6 Next, open the Control Panel, click Programs, and click Turn Windows Features On or Off under Programs and Features. Enable the Windows Subsystem for Linux (Beta) option in the list here and click OK. After you do, you ll be prompted to reboot your computer. Click Restart Now to reboot your computer and Windows 10 will install the new feature. 6

7 After your computer restarts, click the Start button (or press the Windows key), type bash, and press Enter. The first time you run the bash.exe file, you ll be prompted to accept the terms of service. The command will then download the Bash on Ubuntu on Windows application from the Windows Store. You ll be asked to create a user account and password for use in the Bash environment. If you d like to automate the installation of Bash instead, you can run the following command in a Command Prompt window. This will automatically agree to all prompts and set the default user to root with no password: $> lxrun /install /y 7

8 Ubuntu on Windows Using bash shell 8

9 To open the Bash shell, just open your Start menu and search for bash or Ubuntu. You ll see a Bash on Ubuntu on Windows application. You can pin this application shortcut to your Start menu, taskbar, or desktop for easier access. 9

10 Change the appearance of your terminal - Open up Bash on Ubuntu on Windows 10. Right-click the little icon in the upper left hand corner of the window and select Properties. 10

11 Ubuntu on Windows Where are my files?!11

12 Windows 10 s Bash on Ubuntu on Windows environment contains a few different components. The first time you run the bash.exe program, it will download and install an entire Ubuntu user space environment. You can access these files in File Explorer (or other Windows programs), if you know where to look. To access these files, you ll first need to show hidden folders in File Explorer. Open a File Explorer window and click View > Options > Change Folder and Search Options. In the Folder Options window that appears, select View > Show Hidden Files, Folders, and Drives.

14 Where the Ubuntu Files Are Stored in Windows The Ubuntu system files are stored at: C:\Users\ <USERNAME>\AppData\Local\Lxss\rootfs Your Ubuntu user account s home folder is stored at: C:\Users\ <USERNAME>\AppData\Local\Lxss\home\ <USERNAME> C:\Users\<USER>\AppData\Local\lxss\ <USERNAME> The root account s home folder is stored at: C:\Users\ <USERNAME>\AppData\Local\Lxss\root * Replace the <USERNAME> with your Username on Windows.

15 Where the Ubuntu Files Are Stored in Windows You can see your WSL file system from Windows at: %LocalAppData%\lxss\rootfs /root would be located here %LocalAppData%\lxss\rootfs\root and /home would be here %LocalAppData%\lxss\rootfs\home * WSL = Windows Linux Subsytem 15

16 Where Your Windows Drive Appears in Bash The Ubuntu Bash shell makes your full Windows system drive available so you can work with the same files in both environments. However, the Bash environment doesn t just dump you in your C:\ drive. Instead, it places you in /, or the root directory you d have on Linux. If you perform an ls command to view the contents of the directory, you ll just see the Ubuntu directories that provide the Linux environment. Your Windows system drive and other connected drives are exposed in the /mnt/ directory here, where other drives are traditionally made available in the Linux directory structure. Specifically, you ll find the C: drive at the following in the Bash environment: ls -l /mnt/c # replace c accordingly to your system 16 Source: howtogeek.com

17 Where Your Windows Drive Appears in Bash For example, to access a file stored at C:\Users\<USERNAME>\Downloads\File.txt you d need to use the path /mnt/c/users/<username>/downloads/file.txt in the Bash environment. *c: you might change the drive 17

18 Note that, when accessing Windows system files, your Bash shell environment has the permissions it was launched with. If you launched it normally from the shortcut, it will have the same file access permissions your Windows user account does. For example, if you want to access the C:\Users\Administrator folder, you d need to right-click the Bash shell shortcut and select Run as Administrator to launch the Bash shell with Windows Administrator privileges. This works just like the Command Prompt, which needs to be launched as Administrator if you need write access to Administrator-only files, or write access to system files. You can t just use sudo in the Bash environment. 18
