Again with the Bash I need to learn

Wout's back! This time, he's got an entry about running functions under sudo. Not only is this going into my .bashrc, but I've got some reading to do about command and Bash's getopts. (I had looked at getopts in Bash before, but I remember the example code being pretty Byzantine; it was enough to put me off using getopts in Bash at all. This looks much more reasonable.)

Incidentally, I'm writing this on the Linode node/machine/whatever, and there's noticeable lag. The CPU graph on the member's page says there's medium load; web server performance seems to be quite fine, so I'm not sure it's bandwidth. I mention it because this is the first time that's happened; so far, I've been very happy with Linode performance.
