[wplug] suspending processes

[John Harrold]

does anyone know how to suspend a process and resume it? i know that in
bash i can hit control+z and then type fg to resume it. i'm want to suspend
someones process as root and then resume it at a later time. i noticed the
suspend command which is part of bash. it says:


Suspend  the execution of this shell until it receives a SIGCONT signal.
...

what if i'm not trying to suspend a shell but rather a program running in
that shell?

you might ask why i want to do this. i need to take down the file server,
but there are simulations running which can last many days. since these
simulations depend on files on the file server, i want to try to suspend
the processes and hope they don't notice that the file server has
disappeared for a few minutes.
