There are several options but this one will work (Assuming bash or sh):
if [ "$2" == "" ]; then
Also, here is a very handy guide I use for those quick lookups when you
get rusty. It is avail. in PDF and HTML.

I've tried what follows and I still get " if: Expression Syntax ".
#!/bin/tcsh
if [ -z "$2" ] ; then
echo You have not set a file to be appended.
exit 1
fi
Any ideas?

Start by reading the bash manual at:
http://www.gnu.org/manual/bash-2.05a/bashref.html
But you can do a test expression like:
if [[ -z $2 ]]

Simply put, I'm trying to check if $2 is set. Any ideas?
if ( ! $2 ) then
echo You must set a second file
exit 1
fi
