I’m not aware of Linux / AIX specific documentation, but I would imagine some does exist.
Learning relevance and actionscript is fairly universal for all OSes, but there are some specifics that are only available on particular platforms or not available on particular platforms.
Many different parts of the documentation above will list which relevance is available on which platforms.
Do you have a specific example?
For the most part, if you can do it on the command line / terminal, then you can do the same in actionscript.
