installing on ubuntu?

[maxamillionbucks]

I've recently switched computers, i got a new laptop and i have amnesia on my desktop. needless to say i would like to have amnesia on my new laptop, both run ubuntu.
But installing on my laptop has given me a completely different result, i have a file named amnesia_tdd_1.2.sh and i've tried running it every which way and it only wants to run it with text editors, which then fail to open at all.
I may be missing something completely obvious but i really can't find anything on how i should go about using this file.

You need to give the file permission to execute. Most popular file managers let you do this in the file properties.

Either give it permission to run (turn on execute bit), OR run it from the a terminal window like so

sh ./amnesia_tdd_1.2.sh
