Using bash as an example, since fish apparently doesn't do this: bhuda% bash [mwm@bhuda ~/src/chiselapp/straight]$ pwd /export/mwm/src/chiselapp/straight [mwm@bhuda ~/src/chiselapp/straight]$ jobs [mwm@bhuda ~/src/chiselapp/straight]$ suspend 'bash' has stopped bhuda% jobs ~/src/chiselapp/straight|fs:trunk@75f77 Job Group State Command 1 27193 stopped bash bhuda% See the difference? Being able to suspend a shell is a pretty standard feature: bhuda% jobs Job Group State Command 5 27790 stopped bltsh 4 27719 stopped zsh 3 27702 stopped bash 2 27684 stopped csh 1 27666 stopped tcsh bhuda% The only other shell I could find that couldn't be suspended was /bin/sh, which is based on ash. Most programs that aren't shells will catch C-Z to suspend, but the only one of the above that does that is bltsh, and it's really more a tcl interpreter than a shell. The others all have a "suspend" command that suspends them back to whatever program launched them. Unless they're a login shell, in which case it's usually disabled.
