From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Examples of local commands I might run in
tmux
could include anything long-running which is started from the command line. A virtual machine (qemu
), perhaps, or a video encode (ffmpeg
). Then if I need to log out or restart my GUI session for any reason—or something goes wrong with the session manager—it won't take the long-running process with it. While the same could be done withnohup
orsystemd-run
, usingtmux
allows me to interact with the process after it's started.I also have systems which are accessed both locally and remotely, so sometimes (not often) I'll start a program on a local terminal through
tmux
so I can later interact with it through SSH without resorting tox11vnc
.Thanks for the comment. Long-running commands make a lot of sense.
Do you happen to run your GUI session inside of a
tmux
session? If you log in and out, wouldn't thetmux
session inside of the user-session terminate?
