...except, that you should rarely use it. :)

It is much, much faster to pipe commands to "xargs". For instance:

    find . -name core -print0 | xargs -0 rm -f

Since "find" doesn't know when your command is multi-file, it has to run the command once per file; whereas, "xargs" can run it as few times as necessary. It works well for any command that accepts "a list of files".

In the example above, the -print0/-0 are a safety net to null-delimit filenames so that it doesn't matter if any of the paths contains a space.
