This is really a question for -questions, not -hackers. I'm
redirecting accordingly.
That depends on your shell. You *should*, of course, be using a
Bourne-style shell. For that, the syntax is:
for <name> in <list of things> do <things>; done
For example, to compare all the files in the current directory which
also exist in another directory, you might enter:
otherdir=../foo # name of the other directory
for i in *; do
if [ -f $i -a -f $otherdir/$i ]; then
cmp $i $otherdir/$i
fi
done
