Hi Qualidat
A script file is basically a text file that contains commands just like you would type in
a terminal. It can have any name, but you should avoid reserved and system names
like "ls", "cp", etc. Some people put an "sh" extension on them to make it obvious
that it's a script. The difference between a text and a script file is the script file is
marked as executable. To do that run "chmod 755 yourscriptsname", you only need
to do that once and you can still edit it if you need to.
