The program must start with the following line (it must be the first line in the file):
#!/bin/sh
The #! characters tell the system that the first argument that follows on the line is the program to be used to execute this file.
In this case /bin/sh is shell we use.
When you have written your script and saved it you have to make it executable to be able to use it.

Then you can start your script by typing: ./filename
