Cleanup firefox's database.

Output a list of svn repository entities to xml file
I use this to pull the last commit date for everything in my repo, so I can tell the client which files haven't been touched or updated since the repo was created. Another way to do it is to use svn log, but that does not pull the "kind" attribute. It does, however, give you the commit message. Both are very useful.

List the size of all sub folders and files from the current location, with sorting

Create a persistent connection to a machine
Create a persistent SSH connection to the host in the background. Combine this with settings in your ~/.ssh/config: Host host ControlPath ~/.ssh/master-%r@%h:%p ControlMaster no All the SSH connections to the machine will then go through the persisten SSH socket. This is very useful if you are using SSH to synchronize files (using rsync/sftp/cvs/svn) on a regular basis because it won't create a new socket each time to open an ssh connection.

Show git branches by date - useful for showing active branches

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"

prompts for a search term and then pulls down the first result from google images

Check a server is up. If it isn't mail me.
This version uses netcat to check a particular service.

Lists all opened sockets (not only listeners), no DNS resolution (so it's fast), the process id and the user holding the socket. Previous samples were limiting to TCP too, this also lists UDP listeners.

in command mode, navigate your cursor to the line where you want the command output to appear, and hit "!!". No need to enter edit mode or even type a ":" (colon).
