Have you ever needed to collate all of a certain type of file from a disk or a machine? If so the command line “find” tool is a very powerful way search for a specific type of file on a volume or a disk, check out the manual page (man find).
I recently wanted to grab all jpeg files from my machine and put them in a single folder, here’s how I did it:
find / -name “*.jpg” -exec cp {} /Users/pete/jpegs ;
