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.

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.
