[(रेवंत) Revant Nandgaonkar]

if you are using plain ubuntu out of the box Desktop, you wont get
konsole, you'll either have gnome-terminal or xterm

when you open the terminal window, type the following

$ cd Desktop

remember 'D' is in uppercase and the commands, file and directory
names are case sensitive.

now to run the script you've to change its permission to executable

you either right-click on the file and enter properties, under
permissions tab you can check the execute checkboxex

or you can type this in the terminal window, when you are in the
Desktop directory

rachael at ubuntu:~/Desktop$ chmod +x <scriptname.sh>

now to run the script you've to type the following

rachael at ubuntu:~/Desktop$ ./<scriptname.sh>
or
rachael at ubuntu:~/Desktop$ sh <scriptname.sh>
