I need to account for the fact that 789 and 121 of file1 were not found in file2.
Thanks again...
You seem to have a couple of theories about what you want. Your second post seems to solve the problem posed by your first post more or less.
What shell are you using? What system? You should control which shell runs your script with a line like:
#! /usr/bin/ksh
as the first line.
You don't want to print "\n"; just use print. It adds a new line automatically.
That cat process is not doing anything useful. Open the file with exec and then start reading it:
exec < file
while read line
grep will set $? to 1 if there were no matches so you should be ok if you run the script as you posted it...no lines after the grep and before the if.
