\section return return - stop the innermost currently evaluated function
\subsection return-synopsis Synopsis
<tt>function NAME; [COMMANDS...;] return [STATUS]; [COMMANDS...;] end</tt>
\subsection return-description Description
The \c return builtin is used to halt a currently running function. 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.
- \c STATUS is the return status of the function. If unspecified, the status is unchanged.
\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>
