Answer» What COMMAND can I use tolist the files in /usr/include or its subdirectories (possibly nested several layers deep) that contain the string "ptrdiff_t"?find /usr/include -name "ptrdiff_t"That's the most elegant WAY. You could also use ls, thus: "ls -lr /usr/include \| grep ptrdiff_t" which would GIVE you slightly more DETAILED info about the file, but not its ultimate LOCATION.
