break
or continue
was found outside a loop.
These statements are valid only in loops. In particular,
break
is not required in case
statements as
there is no implicit fall-through.
To return from a function or sourced script, use return
.
To exit a script, use exit
.
It's possible to break
/continue
in a
function without a loop. The call will then affect the loop – if any –
that the function is invoked from, but this is obviously not good coding
practice.
