Yes, moreutils has a lot to offer. vidir to quickly reorganize files and folders (even delete files), chronic to run commands silently... unless they fail, sponge to be able to pipe from a file and back to that file without a temporary one ts to add a timestamp to the ouput ...

I find myself using sponge, ts, and pee (tee for pipes: split stdin and send it to two or more different command lines) the most (and in that order).
