Insert a comment on command line for reminder
Comments can be used directly on the command line so I can save in the history a brief description of what command does.

tailf same as tail -f follow the flow of a log file, showing it in real time to stdout.

Which processes are listening on a specific port (e.g. port 80)

Generate a shortened URL with is.gd
Check the API. You shouldn't need sed. The print-newline at the end is to prevent zsh from inserting a % after the end-of-output. Also works with http://v.gd

Setting global redirection of STDERR to STDOUT in a script
You have a script where =ALL= STDERR should be redirected to STDIN and you don't want to add "2>&1" at the end of each command... E.G.: $ ls -al /foo/bar 2>&1 Than just add this piece of code at the beginning of your script! I hope this can help someone. :)

Create a video screencast of any x11 window, with audio
The script gets the dimensions and position of a window and calls ffmpeg to record audio and video of that window. It saves it to a file named output.mkv

phpdoc shortcut
A shortcut to generate documentation with phpdoc. Defaults to HTML; optionally to PDF if third argument is given. Stores documentation in cwd under ./docs/. I forget the syntax to the output, -o, option, so this is easier.
