These are not generic builtins because we check whether they're inside a loop. There's no reason to not support "break -h" when we support "if -h" etc.; do that.

Description
|
|
-----------
|
|
|
|
``break`` halts a currently running loop (*LOOP_CONSTRUCT*), such as a :doc:`for <for>` or :doc:`while <while>` loop. It is usually added inside of a conditional block such as an :doc:`if <if>` block.
|
|
|
|
The **-h** or **--help** option displays help about using this command.
|
|
|
|
Example
|
|
-------
|
|
The following code searches all .c files for "smurf", and halts at the first occurrence.
|
|
|
|
::
|
|
|
|
for i in *.c
|
|
if grep smurf $i
|
|
echo Smurfs are present in $i
|
|
break
|
|
end
|
|
end
