Best summarized by this quote from a coworker: “AIX is what you’d get if aliens implemented a UNIX.”
Utilities exist, but they tend to be different.
There’s also oddities like the compiler (xlC) emitting code that is able to dereference null pointers, with the zero page. It’s a valid but odd choice of undefined behavior. [1]

- sllabres 4y agoThis is a old quote and IIRC was e.g. for the way AIX handles services (SRC / System Resource Controller) and stores configuration data (ODM / Object Data Manager). It felt 'alien' for admins used to use rc scripts (which are possible too) and files in /etc (used in aix too). Now, nearly three decades later, we have even more automated and integrated mechanism 'systemd' and I think that there would be still features worth adopting from AIX. Not the first time i have such thoughts with an OS slowly vanishing.
- skissane 4y ago> “AIX is what you’d get if aliens implemented a UNIX.” The first version of AIX, for the IBM RT PC, actually ran on top of a microkernel written in PL/I, called VRM - how’s that for alien. Subsequent versions moved closer to the Unix mainstream by dropping the PL/I microkernel.
