I hope this is the right list to ask this on. I am creating a shell script for something and the following line (whether run from the script or the command line) gives me an error: if [ ! -z /bin/cat /tmp/BACKUP/tmp | /bin/grep 'not accepted' ] ; then echo hi; else echo no; fi

However, a simpler, cleaner version would be: if [ `grep -c "not accepted" /tmp/BACKUP/tmp` -gt 0 ]; then echo yep else echo nope fi
