Probably only works with GNU du and modern perls.

Press enter and take a WebCam picture.
This command takes a 1280x1024 p picture from the webcam. If prefer it smaller, try changing the -s parameter: qqvga is the tiniest, vga is 640x480, svga is 800x600 and so on. Get your smile on and press enter! :)

stop windows update
Windows only: stops windows update and the nagging restart window. You need your admin password for this one.

Like command 10870, but no need for sed

ssh from local to remote and pipe output of file to the local clipboard

The option -an disables audio recording, -f forces the use of video4linux for the input, -s sets the video to the size 320x240, -b sets the recording bitrate, -r sets the frame rate to 15fps, -i gives the input device, -vcodec sets the output format. Press Q to stop recording or you can specify the recording time with the -t option like -t 00:1:30
