Was quite impressed initially and invested weeks in building new muscle memory, but somehow Zellij crashed with panic more than once, leaving all my processes orphaned. Decided to go back to tmux, and found a simple fix for my Shift+Enter issue.
In case anyone is looking for it, the fix is "bind-key -T root S-Enter send-keys C-j" borrowed from https://github.com/anthropics/claude-code/issues/6072.
I was looking, thank you!
I’ve been relying on the fact that in the worst-case scenario (if a pane hangs and tmux session becomes unresponsive) I can just kill tmux server and not have to hunt down and kill dozens of individual processes afterwards.
The OS will typically not kill orphaned/re-parented processes for you. It will simply wait/reap them so they are not left as zombies once they complete. If your parent process spawns something like a daemon server that needs an explicit signal to be stopped (e.g. SIGINT/SIGTERM), these processes will continue to run in the background until they are manually killed or they crash.
However a different process management model is that each parent must in turn signal its child processes to exit, in which case if the parent dies before that can happen you easily get orphan processes. There are use cases for both the process group model and individual signal models, and pros and cons to each.
$ man prctl
man: No entry for prctl in the manual.
pi.dev keeps complaining that "set -s extended-keys on" is missing, but it still works :D
Terminal programs don’t see key events. It’s all text. I just checked st (suckless) code and the RETURN key will send “\r” aka carriage return. Control+j is “\n” or line feed.
