Get primary IP of the local machine

Plenty of commands out there for finding external IP, but sometimes getting the [internal] IP bound to the NIC handling Internet traffic is useful. Probably not production worthy, but a useful quick kludge. Assumes IPv4 and no fancy routing. Show Sample Output

Grep live log tailing, tracks file open/close

"-F" will continue tailing if file is closed and another file opened with same name. This is handy for tailing log files that segment while watching them without having to issue the command again.

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Get current Xorg resolution via xrandr

Display which distro is installed

Works on nearly all linux distros

split a string (2)

Hide or show Desktop Icons on MacOS

Hides all Files and Folders on the MacOS Desktop. To show files and folders, type "true" instead of "false". "Finder" at the end is case sensitive, "finder" doesn’t work

Hold off any screensavers/timeouts

Moves the mouse 1 pixel down and to the right, then immediately back again, every 4 minutes. This keeps screensavers from turning on. I have used this extensively and I've never even noticed the mouse movement because it is so subtle.

escape any command aliases

e.g. if rm is aliased for 'rm -i', you can escape the alias by prepending a backslash: rm [file] # WILL prompt for confirmation per the alias \rm [file] # will NOT prompt for confirmation per the default behavior of the command

List directories sorted by (human readable) size

Prepend a text to a file.

The original command is great, but I often want to prepend to every line.

Single use vnc-over-ssh connection

This command 1. SSH into a machine 2. Tunnels VNC port to your local computer ("-L 5900:localhost:5900") 3. Runs a single use vnc server ("x11vnc -safer -localhost -nopw -once -display :0") 4. Goes into the background ("-f") 5. Runs VNC viewer on the local computer connecting to the remote machine via the newly created SSH tunnel ("vinagre localhost:5900")
