Empty Trash From Command Line In Ubuntu
CLI is such a sexy piece so why bother using GUI, even for cleaning up your trash. In this post, you will see how you can empty trash in Ubuntu from command line.
The trash you see in GUI is nothing but just the view for the files deleted by users which are temporarily moved to the special location of user's home directory. For any user, the trash location is ~/.local/share/Trash/. That is, whatever a user deletes gets saved in this location.
I hope this becomes useful :)

Disable Guest Account Login In Ubuntu 12.04
Security is an important issue and I do not want anyone to access my machine, not even as the guest. Like almost every operating systems, I could see guest logon option in Ubuntu 12.04 which was turned on by default.

Fire up your terminal and type the following command:
Now add a new line at the end containing the string as below:
Now reboot your system or type the following in your terminal:
The guest account will no longer be active. If you want to enable the guest login again, just remove the line you added or change the value to true. I hope this helps :)
