DEV Community

Articles and discussions should be directly related to Linux operating systems. Questions are encouraged (see the #help tag).

Content with the main focus on bash or the Unix shell is permitted, but don't forget to add the #bash or #unix tag as you see it fitting.

Articles mainly about WSL should be tagged with #wsl instead of #linux.

Linux is a family of free and open source operating systems built on top of the Linux kernel, first released on 1991 by Linus Torvalds.
