When might it be necessary or advisable to write a shell script instead of a shell function?
A shell function will do nothing unless it is explicitly called by other code, typically in a shell script. A shell script is a runnable, executable process, which can call other shell scripts and/or functions. The question might be worded backwards - it is necessary to write shell functions for shell scripts when certain logical functionality is required to be performed multiple times. Consider a shell function equivalent to a program subroutine - they operate the same way.

How do you write shell scripting in UNIX?
A shell script is nothing more than a readable and executable ASCII text file. In this file you put all of the commands that you want to execute, in sequence. The name of the file can be anything you like. Any text editor (VI, VIM, pico, etc) can create a shell script file In addition, shell script files have the ability to detect logic, and are programmable. Just think about what tasks you want to perform and their order, and put it into a file, and there you have a shell script.
