Quick plotting of a function

The arguments of "seq" indicate the starting value, step size, and the end value of the x-range. "awk" outputs (x, f(x)) pairs and pipes them to "graph", which is part of the "plotutils" package.

ping a host until it responds, then play a sound, then exit

After this, just type: beepwhenup You need to install "beep" before this would make the beep sound. Save it in your .profile if you want to use it later WARNING: this command won't exit until it is successful. You won't be able to CONTROL+C out of it.

Countdown Clock

The biggest advantage over atoponce's nifty original is not killing the scrollback. Written assuming bash, but shouldn't be terribly difficult to port to other shells. S should be multiple spaces, but I can't get commandlinefu to save/show them properly, any help?
