Isn't that the same question you asked in your previous thread (7 months ago)?

Generic answer as O/P has not stated Operating System accurately or Shell.

search="our search string"
#
find . -type f -print | while read filename
do
         found=`grep "${search}" "${filename}"`
         if [ ! "${found}""X" = "X" ]
         then
               echo "File ${filename} : ${found}"
         fi
done

Ps. I only posted this because all the answers to the original post were wrong.

The following
$ find . -type f -exec grep -l string {} \;
Will list all the file in the current directory and in sub-directories containing the string.
