return
return <arguments>

Return terminates processing of the current

• alias (command or function) call,
• defer command,
• exec callback,
• load,
• on hook callback,
• queue command,
• timer command,
• wait -cmd callback,
• wait %proc -cmd callback, or
• {…} math operator.

You may optionally supply a return value which will be assigned to the function_return local variable, which is useful from:

• The body of the {…} math operator
• on ?type handlers
• Any alias function call.

Using the return command outside of one of the above contexts yields an error and has no effect.

 alias square (arg) return ${arg * arg}
 eval echo $square(5)

will output
