if you have /path/sub/over/unter/filename.txt and you want to get the filename.txt basename does the trick:

 echo /path/sub/over/unter/filename.txt | basename

Find files matching a certain pattern - weird filename safe & multicore capable

WHATEVER is the pattern you are looking for, 4 is the number of cpus you have available for the job.

find . -type f -print0 | xargs -P 4 -0 echo grep -H WHATEVER
