I am fairly familiar with Linux, I’ve been using different distros for some years now and have done some config editing here and there. I am also a web developer and use the terminal quite a lot and so I always stumble on people’s recommendation to use tmux and how good it is, but I never really understood what it does and, in layman’s terms, how can it be useful and for what use cases.

Can you guys please enlight me a bit on this?

Thank you.

Edit: if my phrasing is a bit awkward or confusing I apologize since I am not an English native speaker. (Maybe that’s why I never fully grasped what tmux is from other explanations xD)

Edite: Ok, just to clarify, my original struggle was to understand what made tmux different from using some terminal app and just split the screen xD

    Tmux is essentially an extension of the concept of running ideas in the background. Like 0xtero mentioned, you use a sort of “virtual terminal” that is persistent (unlike the jobs system you might be familiar with on your shell).

    Now, some people do just use it to split the screen. The idea is it can have multiple terminals, show them, and manage them - it is thus a “multiplexer”, which is where it gets its name (tmux = terminal multiplexer). If you’re on a terminal-only system, this isn’t that bad of a usage.

    Say you’re compiling a large program, like the Linux kernel, and you want to step away, maybe even close the terminal and come back later. Tmux is great for this. You can start the compile in tmux, “detach” (stop viewing it) from it, and it’ll still run full-speed in the background. When you want to look at it again, or check the status, you just re-attach.
