\section return return - stop the current inner function
\subsection return-synopsis Synopsis
<tt>function NAME; [COMMANDS...;] return [STATUS]; [COMMANDS...;] end</tt>
\subsection return-description Description
\c return halts a currently running function. The exit status is set
to \c STATUS if it is given.
It is usually added inside of a conditional block such as an <a
href="#if">if</a> statement or a <a href="#switch">switch</a>
statement to conditionally stop the executing function and return to
the caller, but it can also be used to specify the exit status of a
function.
\subsection return-example Example
The following code is an implementation of the false command as a fish function
<pre>
function false
return 1
end
</pre>
