Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

This is a naive way of finding source code comments in source code files that use C-like comments: // and /*...*/

uniq without pre-sorting

Reads stdin, and outputs each line only once - without sorting ahead of time. This does use more memory than your system's sort utility.

Are the two lines anagrams?

This works by reading in two lines of input, turning each into a list of one-character matches that are sorted and compared.

Syntax Highlight your Perl code

This uses Text::Highlight to output the specified Perl file with syntax highlighting. A better alternative is my App::perlhl - find it on the CPAN: http://p3rl.org/App::perlhl

shell equivalent of a boss button

Nobody wants the boss to notice when you're slacking off. This will fill your shell with random data, parts of it highlighted. Note that 'highlight' is the Perl module App::highlight, not "a universal sourcecode to formatted text converter." You'll also need Term::ANSIColor.
