Microsoft now allows users of the Windows Subsystem for Linux (WSL) to run commands automatically on WSL distribution startup.
WSL is a compatibility layer designed by Microsoft to makes it possible for Windows 10 to run Linux binaries in ELF format natively on Windows computers.
Insiders in the Dev channel who want to upgrade to Windows 10 Build 21286 to gain access to this new feature can do so by going into Windows Update and checking for new updates.
“We have added an option that allows you to run any specified Linux command on startup of a WSL distribution,” Windows Insider Program senior program manager Brandon LeBlanc said.
“You can accomplish this by editing the /etc/wsl.conf file in your distribution and adding an option titled
command under a section titled
For example, as shown in the screenshot below, users can use this new WSL feature to log the time and date their WSL distros were started up.
Once added to the WSL distribution’s /etc/wsl.conf file, the Linux commands will automatically be run when the distro is started.
“WSL distributions will remain running for a few minutes even after the last Linux process inside of them is closed,” LeBlanc added.
“You can view if your WSL distro is running using
wsl --list --verbose and you can manually shut down all WSL distributions using
