K-LUG Linux Challenge and Puzzler #3

This challenge has ended. Here are the answers.

Challenge

Make a directory and figure out how to delete it without using rmdir. (Think about how other things are deleted.)

When you figure it out, explain how you did it and send it to NeffK@IEEE.Org with the word "challenge" in the subject line.

Puzzler

Using any programming language you like, generate a level 1 postscript file that describes the shape of an arrow. That is, if you were drawing an arrow from text to a graphic, you'd draw a line and a arrowhead. Draw the arrow body 1" and draw an arrowhead that looks right. Scale, rotate, and translate your arrow so that it is displayed 4 times on a letter sized page.

Mail the answer and the postscript file to NeffK@IEEE.Org with the word "puzzler" in the subject line to win.

Prize

The sticker or emblem or your choice from Think Geek.
