....my collection of useful (hopefully) scripts 

Here are the scripts I've written for Ubuntu, they are grouped for your convenience:

System Scripts:

These scripts enhance the system in some way:

AutoFsck V2.0:
AutoFsck will be documented here at some point, but for now please visit:
https://wiki.ubuntu.com/AutoFsck

Nautilus Scripts:

These scripts are extensions to the nautilus file manager.  Right click on the script you want, and save it in /home/yourname/.gnome2/nautilus-scripts (if that directory doesn't exist, create it).  Then, run this from the command line:
nautilus ~/.gnome2/nautilus-scripts/
and in nautilus, right click the file, select 'properties' select 'permissions', and check the box to allow execution of the file.  If you're using an older version of nautilus, the option may be different, but you must give yourself execute permission.  After you've done that, the script will show up in the nautilus-scripts menu when you right click.  The name of the file will be used as the menu entry, so if you want the menu item to say "script to do something cool", you'll have to rename the file to that.

ccryptgui:
Ccryptgui is a script for nautilus which encrypts or decrypts files using the ccrypt command line program.  Ccrypt uses the Rijndael cipher, which is the Advanced Encryption Standard (AES).  After installation (see above) the script can be used by right clicking on a file, going to the scripts menu, and selecting "ccryptgui" (unless you've renamed the file - I suggest renaming it to "Encrypt or Decrypt - ccrypt").  The script will then prompt you to select whether to encrypt or decrypt the selected file.
