return - stop the current inner function¶
Synopsis¶
function NAME; [COMMANDS...;] return [STATUS]; [COMMANDS...;] end
Description¶
return
halts a currently running function. The exit status is set to STATUS
if it is given.
It is usually added inside of a conditional block such as an if statement or a switch 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.
Example¶
The following code is an implementation of the false command as a fish function
function false
return 1
end
