Check These Out

Get the total length of time in hours:minutes:seconds (HH:MM:SS) of all video (or audio) in the current dir (and below)
change the *.avi to whatever you want to match, you can remove it altogether if you want to check all files.

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"

a fast way to repeat output a byte
I'm both a one-liner fan and a haskell learner

Convert seconds to [DD:][HH:]MM:SS
Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Stream YouTube URL directly to MPlayer
A function for streaming youtube to mplayer. The option "-g" for youtube-dl tells it to output the direct video URL, instead of downloading the video. "-fs" tells MPlayer to go FullScreen, and "-quit" makes it less verbose. Requires: youdube-dl ( http://bitbucket.org/rg3/youtube-dl/ ) (Tested in zsh)

Display any tcp connections to apache
Sometimes apache will get stuck in an established state where you can't get a list of the connecting IP's from mod_status... not a good thing when you need to ban an abusive ip.

Reset hosed terminal,
stty sane resets the tty to basic usable function. The ^J is a newline -- sometimes CR/LF interpretation is broken so use the ^J explicitly.

convert binary data to shellcode

list files recursively by size

Say something out loud
Whatever arguments you pass will be spoken out loud. (Put it in a script or shell function.)
