Poor man's unsort (randomize lines)

If you need to randomize the lines in a file, but have an old sort commands that doesn't support the -R option, this could be helpful. It's easy enough to remember so that you can create it as a script and use that.

It ain't real fast. It ain't safe. It ain't super random. Do not use it on untrusted data. It requires bash for the $RANDOM variable to work.

grep (or anything else) many files with multiprocessor power

xargs -P N spawns up to N worker processes. -n 40 means each grep command gets up to 40 file names each on the command line.

Send email with one or more binary attachments

This command uses mutt to send the mail. You must pipe in a body, otherwise mutt will prompt you for some stuff. If you don't have mutt, it should be dead easy to install.
