return [ n ]
Causes a shell function or `.' script to return to the invoking
script with the return status specified by an arithmetic
expression n. If n is omitted, the return status is that of the
last command executed.
If return was executed from a trap in a TRAPNAL function, the
effect is different for zero and non-zero return status. With
zero status (or after an implicit return at the end of the trap),
the shell will return to whatever it was previously processing;
with a non-zero status, the shell will behave as interrupted
except that the return status of the trap is retained. Note that
the numeric value of the signal which caused the trap is passed as
the first argument, so the statement `return $((128+$1))' will
return the same status as if the signal had not been trapped.
