Check These Out

Help shell find freshly installed applications (re: PATH)
Immediately after installing things into your PATH (e.g. under /usr/bin), currently open shells cannot find them ("zsh: command not found"). Use rehash to get the shell to rescan available executables.

check open ports
Tested in Linux and OSX

Which .service related this file?
I use this as an alias to get all .service files related a single installed file/conf (if it has services, of course). For rpm based systems ;)

Make alias pemanent fast
Simple function to permanently add an alias to your profile. Tested on bash and Ksh, bash version above. Here is the ksh version: PERMA () { print "$@" >> ~/.profile; } Sample usage: PERMA alias la='ls -a'

prettier "cal" command
Displays the same output as "cal", but with the current day highlighted (probably dependent on gnu grep, as I'm not sure other grep's support the "--color=auto" option). Tested and working on Ubuntu 11 and OSX Lion.

intercept stdout/stderr of another process

GRUB2: set Super Mario as startup tune
I'll let Slayer handle that. Raining Blood for your pleasure.

Gets the english pronunciation of a phrase
Usage examples: say hello say "hello world" say hello+world

Get duration of an audio file in seconds.
This is an alternative to #9131. ffmpeg didn't work on my .au files, though it did on the .wav ones. Also useful if you don't have ffmpeg but do have sox. Handily, sox already reports in seconds (decimal).

Fast portscanner via Parallel
