Hi!

                              Hmm why don't we remove the
			      "pname='pname -i'" from the parameters?

			      If we silently ignore the failure it's the
			      same as if we haven't checked it in the
			      first place...

Also it would be good to be a bit more verbose here. I.e. do:

echo "'$1' not found in:
cat temp
echo

I would rather do 'if [ $# -gt 2 ]; then' but that is very minor.

The rest looks good.
