Check These Out
One of my favorite ways to impress newbies (and old hats) to the power of the shell, is to give them an incredibly colorful and amazing version of the top command that runs once upon login, just like running fortune on login. It's pretty sweet believe me, just add this one-liner to your ~/.bash_profile -- and of course you can set the height to be anything, from 1 line to 1000!
$ G=$(stty -g);stty rows $((${LINES:-50}/2));top -n1; stty $G;unset G
Doesn't take more than the below toprc file I've added below, and you get all 4 top windows showing output at the same time.. each with a different color scheme, and each showing different info. Each window would normally take up 1/4th of your screen when run like that - TOP is designed as a full screen program. But here's where you might learn something new today on this great site.. By using the stty command to change the terminals internal understanding of the size of your terminal window, you force top to also think that way as well.
# save the correct settings to G var.
$ G=$(stty -g)
# change the number of rows to half the actual amount, or 50 otherwise
$ stty rows $((${LINES:-50}/2))
# run top non-interactively for 1 second, the output stays on the screen (half at least)
$ top -n1
# reset the terminal back to the correct values, and clean up after yourself
$ stty $G;unset G
This trick from my [ http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html bash_profile ], though the online version will be updated soon. Just think what else you could run like this!
Note 1: I had to edit the toprc file out due to this site can't handle that (uploads/including code). So you can grab it from [ http://www.askapache.com/linux-unix/bash-power-prompt.html my site ]
Note 2: I had to come back and edit again because the links weren't being correctly parsed

Substitute whatever track number you want into the "dvd://1" parameter. The "-aid 128" is to select the English language.
Simply changes the wallpaper of xfce4 from the command line. Not for multiple displays.
Creates one letter folders in the current directory and moves files with corresponding initial in the folder.
Extracts the model name of the CPU and displays it on screen.
This should automatically mount it to /media/truecrypt1. Further mounts will go to /media/truecrypt2, and so on. You shouldn't need sudo/su if your permissions are right.
I alias tru='truecrypt' since tr and true are commands.
To explicitly create a mount point do: tru volume.tc /media/foo
To make sure an GUI explorer window (nautilus, et al) opens on the mounted volume, add: --explorer
To see what you currently have mounted do: tru -l
To dismount a volume do: tru -d volume.tc. To dismount all mounted volumes at once do: tru -d
Tested with Truecrypt v6.3a / Ubuntu 9.10
The command will read the apache log file and fetch the virtual host requested and the number of requests.
To install a theme use:
$ sudo firefox -install-global-theme /path/to/theme
You can get the .xpi or .jar file from the versions history on the add-on/theme page.
NOTE: may not work in your system (Debian-based is an example).
