================================================

Synopsis
--------

::

    if CONDITION; COMMANDS_TRUE...; [else; COMMANDS_FALSE...;] end

Description
-----------

:ref:`if <cmd-if>` will execute the command ``CONDITION``. If the condition's exit status is 0, the commands ``COMMANDS_TRUE`` will execute. If it is not 0 and ``else`` is given, ``COMMANDS_FALSE`` will be executed.


Example
-------

The following code tests whether a file ``foo.txt`` exists as a regular file.


::

    if test -f foo.txt
        echo foo.txt exists
    else
        echo foo.txt does not exist
    end
