--------------------------------------------------------------
Show differences between two tokenized Atari 8-bit BASIC files
--------------------------------------------------------------
.. include:: manhdr.rst
SYNOPSIS
========
diffbas [*diff-options*] [**--** *listbas-options*] *file1* *file2*
DESCRIPTION
===========
**diffbas** shows the differences between two tokenized (SAVEd)
Atari BASIC programs, using **listbas**\(1) and **diff**\(1).
OPTIONS
=======
**diffbas** takes no options of its own. It will pass options as-is
to both **listbas** and **diff**. Use **--** to separate them: everything
before **--** is passed to **diff**, and everything between **--** and
the first filename is passed to **listbas**.
COLOR
=====
By default, the output is colorized by **listbas**. If you want to use
**diff**\'s **--color** option, you should use **-n** as a **listbas**
option. Color diffs are most useful with **-u** (unified diff format),
so the command would look like::
$ diffbas -u --color -- -n A.BAS B.BAS
EXAMPLE
=======
::
$ diffbas -u A.BAS B.BAS

EXIT STATUS
===========
0 for success. On failure, the exit status is that of whichever command
failed (**listbas** or **diff**).
