How do I save a text file with the `.sh` extension?

New to using .sh on Mac. Simple question - how do I save a text file with extension .sh? I've exhausted my limited knowledge. I need to do this conversion to test run scripts on OS X. Though, with what I've gleaned from the web, Linux is much easier to navigate.

1. If you are familiar with the cmd, use vim or touch in terminal(Launchpad--others--terminal or just Spotlight--terminal) just like you do in linux.
2. Use TextEdit to create a new document. After saving this document, add a .sh to rename it.
3. Third party textedit softwares are also available for suffix change.
