[TriLUG] Making a bg'd bash script wait for user intervention

[Brian Henning]

Hi Y'all,
  I'm working on a set of scripts for backups, and I've hit a snag in a
script that burns images to CDs.  I need it to wait for user intervention in
certain situations (no CD in drive, CD not blank, swap CDs now, etc).  I've
got the various conditions mapped out in the script; all I need is a way to
make it wait for me to say "go", basically.  The trick is that the process
may be backgrounded, so it can't be simply waiting for Enter on stdin (or
can it?).  I tried suspend, but I get
suspend: cannot suspend: no job control

Is there another simple method to make a bash script wait for a signal?  Or
else, what do I need to do to make suspend work?

Thanks muchly,
~Brian
