A very quick and slick fork bomb. Handle with care. Don't run on production please...

ThePirateBay.org torrent search
This one-liner greps first 30 direct URLs for .torrent files matching your search querry, ordered by number of seeds (descending; determined by the second number after your querry, in this case 7; for other options just check the site via your favorite web-browser). You don't have to care about grepping the torrent names as well, because they are already included in the .torrent URL (except for spaces and some other characters replaced by underscores, but still human-readable). Be sure to have some http://isup.me/ macro handy (someone often kicks the ethernet cables out of their servers ;) ). I've also coded a more user-friendly ash (should be BASH compatible) script, which also lists the total size of download and number of seeds/peers (available at http://saironiq.blogspot.com/2011/04/my-shell-scripts-4-thepiratebayorg.html - may need some tweaking, as it was written for a router running OpenWrt and transmission). Happy downloading!

Indent a one-liner.
Bash builtin type also indents the function.

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

list files recursively by size

Count the total amount of hours of your music collection
First the find command finds all files in your current directory (.). This is piped to xargs to be able to run the next shell pipeline in parallel. The xargs -P argument specifies how many processes you want to run in parallel, you can set this higher than your core count as the duration reading is mainly IO bound. The -print0 and -0 arguments of find and xargs respectively are used to easily handle files with spaces or other special characters. A subshell is executed by xargs to have a shell pipeline for each file that is found by find. This pipeline extracts the duration and converts it to a format easily parsed by awk. ffmpeg reads the file and prints a lot of information about it, grep extracts the duration line. cut and sed cut out the time information, and tr converts the last . to a : to make it easier to split by awk. awk is a specialized programming language for use in shell scripts. Here we use it to split the time elements in 4 variables and add them up.
