`C-z' is bound to 2 different commands, depending on the -nw option:

C-z runs the command iconify-or-deiconify-frame
C-z runs the command suspend-emacs

So running under a window system, you could not expect `C-z' to suspend emacs.


In both cases, `C-g' will interrupt the shell command.

Just use `M-!' instead of `!', and terminate your command with "&" to run it

in the background so you can continue to use emacs (including `C-z') any way
you wish.
