Hi ust,
You can't use find to get same content. Instead you must use a gawk script to do the job. Make your own gawk script. Help at "info gawk"

Hi,

Won't this do:

Code:
for THIS in `cat file1 | grep -v '#'`
do
grep $THIS file2
done
Or as 'oneliner':

for THIS in `cat file1 | grep -v '#'`; do grep $THIS file2 ; done

Will need some work if the inputlines have 'funny' characters.

Hope this helps.
