Check These Out

Execute a sudo command remotely, without displaying the password
The ssh command alone will execute the sudo command remotely, but the password will be visible in the terminal as you type it. The two stty commands disable the terminal from echoing the password back to you, which makes the remote sudo act as it does locally.

Watch several log files in a single window
It works like a "tail -f" on several files. Use the number keys 0-9 to set a baseline in the numbered window. Pressing "b" let you scroll back in one of the windows.

Eavesdrop on your system
This command takes a snapshot of the open files for a PID 1234 then waits 10 seconds and takes another snapshot of the same PID, it then displays the difference between each snapshot to give you an insight into what the application is doing.

Weather on the Command line
Get your weather from a weather station just blocks from your home. Go to http://www.wunderground.com/wundermap/ and find a weather station near you. Click on a temperature bubble for that area. When the window pops up, click on hypertext link with the station ID, then on the bottom right of the page, click on the Current Conditions XML. Thats your link! Good luck!

reverse order of file

Protect directory from an overzealous rm -rf *
-R Recursively change attributes of directories and their contents. +i to set the immutable bit to prevent even root from erasing or changing the contents of a file.

Convert (almost) any video file into webm format for online html5 streaming

Run a command when a file is changed

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

List all authors of a particular git project
Gets the authors, sorts by number of commits (as a vague way of estimating how much of the project is their work, i.e. the higher in the list, the more they've done) and then outputs the results.
