Display a wave pattern

Purely frivolous - print a sine/cosine curve to the console - the width varies as it progresses. Ctrl-C to halt.

Convert seconds to human-readable format

This example, for example, produces the output, "Fri Feb 13 15:26:30 EST 2009"

Colorize grep output

Translates a phrase from English to Portuguese

Translates a string from English to Portuguese by using google translator web service.

Print current runlevel

Change the homepage of Firefox

This command modifies the preferences file of Firefox that is located in .mozilla/firefox/*.default/prefs.js. It edits the file with sed and the -i option. Then it searches the string "browser.startup.homepage", and the string next to it (second string). Finally, it replaces the second string with the new homepage, that is http://sliceoflinux.com in the example. It doesn't work if you haven't set any homepage.
