# 22  
Old 01-28-2011
Code:
grep -i "abc" filename.txt ; REPLY=$?
if [ ${REPLY} -eq 0 ]
then
          echo "Found abc in filename.txt"
else
          echo "Did not find abc in filename.txt"
fi

On most versions of "grep" the value of $REPLY would be "1" if the string was not found.

Hope this helps.
