returnCause a shell function to exit with the return value n.
SYNTAX return [n] OPTIONS n : return value (errorlevel)
If n is not supplied, the return value is the exit status of the last command
executed in the function. This may also be used to terminate execution of a
script being executed with the . (or source) builtin, returning either n or
the exit status of the last command executed within the script as the exit status
of the script.
The return status is false if return is used outside a function and not during the execution of a script by . or source.
return is a BOURNE shell command and a POSIX `special' builtin.
