Terminal Program through Text Files
 

in Windows u could save a test file as *.bat and it will work as command prompt
what should I save the text file in Linux so it would work as Terminal Program directly??

In *nix it's called shell scripting, and it's more flexible than windows scripting. You can create anything from a simple as a list of commands to rather complex programs. There are many tutorials for it on the net. For example:
