I have a bash alias for this command line and find it useful for searching C code for error messages.
The -H tells grep to print the filename. you can omit the -i to match the case exactly or keep the -i for case-insensitive matching.
This find command find all .c and .h files
-sl : show just file names
Old Sys5 system and SUN computers don't have the -H option. Adding /dev/null forces grep to use the multi-file output and report the file name.
Original submitter's command spawns a "grep" process for every file found. Mine spawns one grep with a long list of all matching files to search in. Learn xargs, everyone! It's a very powerful and always available tool.
