AIX versus Unix commands
aix, command-line, unix
Solution
The IBM `publib` documentation for System p and AIX is stored here - `publib` is a vital resource if you're using any IBM product.
Look under `AIX Documentation`, `Commands reference`, `Categorical`(1). This will show you what the commands are meant to do from which you'll hopefully be able to work out the similar commands for other operating systems.
(1) Though, of course, things have moved since this answer was originally given (in 2009). You're looking for any resource that shows the `man` pages for AIX. Alternatively, assuming you have access to an actual AIX box, you should be able to enter (for example) `man ls` for a specific command, or `man -k directory` for a keyword search of commands related to directories.
Problem
I need all the Unix commands which are specific to AIX machines. For e.g.: for Unix `top` is equivalent to `topas` in AIX. I need the list of similar commands. Where can I find it? Is there any documentation for this?
