But the source code is spread over several directories and .cpp's and .h's. It would be hard to all of them to one file and then search through it. There is got to be a better way. Thanks for taking time.

[tt]grep -Hr 'string' /path/to/source/code[/tt]
should print out the filename followed by the line [tt]string[/tt] appeared on.

Check the system, if you have access to the development tool cscope, it is quite powerful and useful.

You can use it to search an entire project's list of source files for any variable you want.

Cheers!

The grep command worked beautifully. Thank you Dan.
