Since nobody has said yet, I use screen pretty heavily. Want to run a long running task, starting it from your phone? Run screen to create a detachable session then the long running command. You can then safely close out of your terminal or detach with ctrl a, d and continue in your terminal doing something else. screen -r to get back to it.

I recently switched to tmux and boy, it's way better. I basically use only tmux now anymore. Creating panes to have two processes in one glance, multiple windows, awesome. Plus all the benefits of screen.

[–] krash@lemmy.ml 3 points 3 months ago

Try zellij. Not as popular as tmux, but very intuitive to use.

Maybe someone reading wants to now about prefix+s. This doubles your excitement.

In a similar vein, nohup lets you send tasks to the background and seems to be everywhere.

[–] pyr0ball@sh.itjust.works 3 points 2 months ago (2 children)

You can't mention nohup without at least mentioning kill -9 or pkill to slay the monster you created you madman

Sometimes I'll just reboot the entire damn machine just to be safe ;)

[–] Sorse@discuss.tchncs.de 2 points 2 months ago

shutdown -r now

Eyyy, don't hate, this is how I start all my work programs. That command is really nice and creates all work programs as children of a single terminal session for easy closing later.

[–] pyr0ball@sh.itjust.works 2 points 2 months ago

No hate! Just need to make sure people know so they don't create a bazillion threads without realizing it, or how to stop them effectively

Also, screen can connect to an UART device or serial or anything that offers up a TTY

Don’t use screen, but I do use tmux pretty heavily.

[–] muzzle@lemm.ee 2 points 3 months ago (1 children)

I Always forget to run screen first, so I just rely heavily on dtach

[–] 7dev7random7@suppo.fi 1 points 3 months ago (1 children)

Simply change your terminal command to execute the terminal multiplexer of your choice.

man terminal_of_choice, look for (start) command.

[–] muzzle@lemm.ee 1 points 2 months ago

No thanks, I'm good

How does screen / tmux work when detached from a session, how does it keep the session alive (both when running locally, and while ssh:ing to a server)? Is there a daemon involved?

[–] darvit@lemmy.darvit.nl 1 points 2 months ago

You can find out by running screen and executing pstree, that way you can see how the screen process is run.
