# Run this script every time you want to update
# your terminals background image.
#

# This is really all you need to setup. Point it to a directory
# with all of your background images.
BGPATH=/home/angrylogic/Documents/Backgrounds
FILTERS="*.jpg *.JPG *.png *.PNG *.tiff *.TIFF *.gif *.GIF"
PROFILE=Default

# Set counters and lists to nothing

# Generate the list of pictures depending on wither or not
# we are doing extension filtering. If your directory has
# non-image files, you want to use filtering.
if [ -n FILTERS ]
then
       PIC_LIST=`ls -1 $BGPATH`
else
       for FITLER in FILTERS
       do

# FIXME:
# If anyone knows a better way of extracting a certain element
# from a list in bash please email me. I couldn't find anything in
# my poking around and I couldn't get the cut utility to take
# space as a delimiter
for PICTURE in $PIC_LIST
do
       let NUM=$NUM+1
       # Loop until we find our lucky picture in the list, and set
       # that up as the background picture.

Change mouse cursor theme in Gnome

f you don't like the default mouse cursors, here is how to change it:

1) Download "mouse theme" you like:
- here is one place to download -> gnome-look-org
2) Copy(as root) downloaded archived file in /usr/share/icons:
cp example.tar.bz2 /usr/share/icons/

3) Go to that directory and unpack the archive:
tar xvfj example.tar.bz2
The directory with your icon name should be created here.(/usr/share/icons/Example)

Note: Some icon themes come with two or three different colors, so extracted directory will contain subfolders name like "Black" "White" "Blue" ....
You should move subfolder to /usr/share/icons/ directory like this:
mv /usr/share/icons/Example/Black /usr/share/icons/
Now the /usr/share/icons/Black foder is here where it should be.

4) Edit the file with your text editor located in /usr/share/icons/default/index.theme
gedit /usr/share/icons/default/index.theme
Change the line "Inherits=Bluecurve" to whatever your new mouse icon theme directory is named. (Inherits=Example, Inherits=Black, Inherits=Blue,...)

5) Save the file and log out of your session.
When you login, the new mouse icon theme should be in use.
