How to exit a function in bash

Question

How would you exit out of a function if a condition is true without killing the whole script, just return back to before you called the function.

Example

Answer 1

Use:

return [n]

From help return

return: return [n]

Return from a shell function.

Causes a function or sourced script to exit with the return value
specified by N.  If N is omitted, the return status is that of the
last command executed within the function or script.

Exit Status:
Returns N, or failure if the shell is not executing a function or script.
