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.

Stream your desktop to a remote machine.

This allows you to stream your desktop using vlc to another computer, in this case, 192.168.1.2 on your local network. If you have vlc installed, your all set to try this out. To view your own desktop, just run "vlc screen://" For more info, see http://nerdlogger.com/2008/01/08/stream-your-linuxwindowsmac-desktop-as-video-using-vlc/

list block devices

Shows all block devices in a tree with descruptions of what they are.

Checks apache's access_log file, strips the search queries and shoves them up your e-mail

as unixmonkey7109 pointed out, first awk parse replaces three steps.

Show 'Hardware path'-style tree of all devices in Linux

Generate an XKCD #936 style 4 word password

4 random words are better than one obfuscated word http://xkcd.com/936/

Exclude multiple columns using AWK

Print all columns except the 1st and 3rd.

Currency Conversion

eg: currency_convert 1 usd inr

display a smiling smiley if the command succeeded and a sad smiley if the command failed

you could save the code between if and fi to a shell script named smiley.sh with the first argument as and then do a smiley.sh to see if the command succeeded. a bit needless but who cares ;)

check python syntax in vim

Using ASCII Art output on MPlayer

Not so useful. Just a cool feature.
