[yurenchen000]

how about add ctrl+z for job control support?

#192 mentioned this featrue.

maybe I can send a PR

[yurenchen000]

here is the RP
#250

I only tested on ubuntu 22, and it just work.

seems tcell and tview not support ctrl+z for job control (so that almost all app based on them also not suppor it)
I can't live without ctrl+z (I noticed the b to spawn shell, but that not what I want).

here is a wrokaround, I only known It can work on ubuntu (maybe).
//seems a small probability terminal state borken

I want this too. Sometimes I just think I don't need the shell and not start tmux before running gdu, only to find later that I do want to check some files. Opening another connection works but takes time, and it's one more window to manage.

b works, but it's just not my usual workflow. Exiting current shell is a bit dangerous because I may exit elsewhere accidentally to close the connection and lose my context.

@lilydjwg
exactly, you speak my heart

so I also thought the b embed shell should use a different PS1 prompt

for important bash session set -o ignoreeof¹ maybe useful
