Need unix command file HELP!

> We are looking for a utility that can, when given a arbitrary string,

> The utility would return all the files (and their pathnames from the

> and 'awk' commands but we just can get it right.
> Please send source code (or ideas on writing this code) to us and we
> will post to net a summary of working code.

# In ksh or sh this is a one-liner:
2>/dev/null find / -exec fgrep -l $1 {} \;
