Compiling a shell script.

To create a new file in unix based environments we can use text editors like vi, vim, emacs, gedit,etc..

If you use vi editor, for compiling and executing a shell script then follow the steps given below,

1. Just open terminal and type as “vi <file_name>.sh” and enter (.sh is extension for shell script)

2. Write required script and save the script by using shift+;(semi-colon) and w.

3. To quit the editor you need to press shift+;(semi-colon) and q. (Note:Both q and w are lower-case)
