So I have this script:

#!/bin/bash

case $current_orientation in
        normal)
                current_orientation=0

        left)
                current_orientation=1

It's for flipping screen in my Lenovo S10-3t. I copied it from the netbook's wiki page, and added the #!/bin/bash at the top. The filename is flipscreen.sh. How can I make it work?

Right click on the file, then choose "Properties". From the dialog check the "Allow executing file as program" like in the picture below. Then close the dialog and double-click on the file to execute.

First you need to make your file executable,

in directory type,

sudo chmod+x flipscreen.sh

sudo bash flipscreen.sh

I most cases you don't need sudo. If you don't need it, you must not use it. –  Aleksandr Levchuk May 1 '11 at 3:22

OpenNingia's answer will work, but for those who will come googling later, you can also do through the commandline:

open terminal, and goto the folder where your script is located

chmod +x <yourScript>

then execute it as

./<yourScript>

add a sudo at the beginning if the script is not in your home directory. –  theTuxRacer Nov 11 '10 at 9:45

Double click on the file. A dialogue box will ask you that the said file is executable what do you want to do. Click "run" and you should be good to go.
