Generate a random password 30 characters long

find external links in all html files in a directory list
Just a handy way to get all the unique links from inside all the html files inside a directory. Can be handy on scripts etc.

Archive all folders in a directory into their own tar.bz2 file
Remove the "echo" to actually archive. Many similar commands are found on commandlinefu but I end up needing this very specific one from time to time. To extract any of them, use the standard tar.bz2 extract command: $tar xvjf folder1.tar.bz2

Convert multiple flac files to mp3
make sure that flac and lame are installed sudo apt-get install lame flac

True Random Dice Roll
/dev/urandom is cryptographically secure, and indistinguishable from true random, as it gathers data from external sources, influenced by human timing interactions with computers, to fill the entropy pool, and hashes the input with SHA-1. As such, this is a quick way to do a "true random" fair-6 dice roll. Using this method, you could easily create passphrases with Diceware http://diceware.com. Change the head(1) count to something other than 5 for more or less numbers.

Disconnect telnet
You are stuck with testing a tcp port using telnet, and must kill the telnet session from another terminal... Or, press ctrl+5 and write close/quit to force the current connection to close..

show the real times iso of epochs for a given column
When you have one of those (log)files that only has epoch for time (since no one will ever look at them as a date) this is a way to get the human readable date/time and do further inspection. Mostly perl-fu :-/
