...making Linux just a little more fun!

Most CLI aficionados use this kind of construct when executing a command over "find" results:
$ find ~ -type f -exec du -k {} \;
Nothing is wrong with that, except that "du" is repeatedly called with single argument (that is the absolute path and the file name itself). Fortunately, there is a way to cut down the number of execution:
$ find ~ -type f -exec du -k {} +
Replacing ";" with "+" would make "find" to work like xargs does. Thus du -k will be examining the size of several files at once per iteration.
PS: Thanks to tuxradar.com for the knowledge!
