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.

echo 'alias monitor_off="sleep 1; xset dpms force standby"' >> ~/.bash_aliases ; . ~/.bash_aliases # now monitor_off does what you think

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

perl -ne 'print if !$a{$_}++'

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

(echo foobar; echo farboo) | perl -E 'say[sort<>=~/./g]~~[sort<>=~/./g]?"anagram":"not anagram"'

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

perl -MText::Highlight -E '$h=Text::Highlight->new(ansi=>1); my $text=do{local $/; open my $fh, "<", $ARGV[0]; <$fh>}; say $h->highlight("Perl", $text);' path/to/perl-file.pl

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

cat /dev/urandom | hexdump -C | highlight ca fe 3d 42 e1 b3 ae f8 | perl -MTime::HiRes -pne "Time::HiRes::usleep(rand()*1000000)"

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.
