Recursive replace of directory and file names in the current directory.
This should work anywhere perl and grep is available. :P

Selecting a random file/folder of a folder
Also looks in subfolders

Start another X session in a window
You might have Xnest (older) rather than Xephyr. You can experiment with other desktops eg: startx /usr/bin/start-kde -- /usr/bin/Xephyr :2 You can start X on a remote machine (although I'd recommend vnc for anything slower than a LAN): startx /usr/bin/ssh -X gnome-session -- /usr/bin/Xephyr :2 Or just start another X session locally talking to the remote backend:

back ssh from firewalled hosts
host B (you) redirects a modem port (62220) to his local ssh. host A is a remote machine (the ones that issues the ssh cmd). once connected port 5497 is in listening mode on host B. host B just do a ssh 127.0.0.1 -p 5497 -l user and reaches the remote host'ssh. This can be used also for vnc and so on.

Create sqlite db and store image
Creates a simple sqlite db (img.db) inserts /tmp/Q.jpg on base64 an recorvers it as /tmp/W.jpg

Get your external IP address ( 10 characters long )
Shortest url to a external IP-service, 10 characters.

MySQL: Slice out a specific table from the output of mysqldump
Only filters the statement related to a specific table ('departments', in the example), from the output of mysqldump

Print IP of any interface. Useful for scripts.

Backup a remote database to your local filesystem
I have this on a daily cronjob to backup the commandlinefu.com database from NearlyFreeSpeech.net (awesome hosts by the way) to my local drive. Note that (on my Ubuntu system at least) you need to escape the % signs on the crontab.

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