Search a string and generate a error message.

Comment:

Hi Frens, I have to search for a string and need to display a error message if that sting is not found in the file.... I can use the command: > grep "String" filename for searching the string but, in addition to that I have to add - if that string not found echo "Sting not found " Can anyone help me for this? Thanks in advance...
