Check These Out

Control ssh connection
SSH can be controlled trough an ~ escape sequence. Example, to terminate the current ssh connection, type a newline, then the ~ character, and last a . character. This is useful eg when an ssh connection hangs after you reboot a machine and the connection hangs.

Start a HTTP server which serves Python docs
I use this command to start a local Python document server over HTTP port 8888.

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.

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"

Grab a list of MP3s out of Firefox's cache
Grab a list of MP3s (with full path) out of Firefox's cache Ever gone to a site that has an MP3 embedded into a pesky flash player, but no download link? Well, this one-liner will yank the *full path* of those tunes straight out of FF's cache in a clean list. Shorter and Intuitive version of the command submitted by (TuxOtaku)

How many files in the current directory ?
A simple "ls" lists files *and* directories. So we need to "find" the files (type 'f') only. As "find" is recursive by default we must restrict it to the current directory by adding a maximum depth of "1". If you should be using the "zsh" then you can use the dot (.) as a globbing qualifier to denote plain files: zsh> ls *(.) | wc -l for more info see the zsh's manual on expansion and substitution - "man zshexpn".

Scan Network for Rogue APs.
I've used this scan to sucessfully find many rogue APs on a very, very large network.
