Hmm, this should be in the man pages.
Anyway, when grep exits it puts out a return code, 0 if it found something,
1 if it didn't. That return code is saved in $?
So the script would look something like this:
#!/bin/sh
for file in /var/mail/*
do
grep <keyword> $file >/dev/null
if [ $? == 0 ]; then
mv $file /tmp/review
mv caughtyou $file
fi
done
The rest is left as an exercise. :-)
