Exec is a microkernel. Intuition is nothing like X. AmigaDOS (the part the command line uses) is based on an OS (TripOS) that shares a few basic ideas with Unix, but is heavily redesigned. That's for starters.
The "everything is a file" metaphor used in Unix is not present in AmigaOS, though many devices do have handlers that allow the system to treat them as files, or actually volumes. AUX: comes to mind, as does SPEAK:. But in general, AmigaOS has an entirely different system for managing system devices.
AmigaOS does not have one single root level. Every system volume has its own root level, and may have as many as 3 different volume names by which it may be addressed. (Think SYS:, HD0:, and Workbench:.) AmigaOS does not feature, and does not support, multi-user facilities.
AmigaOS does not have good pipe support. The PIPE: device is a decent workaround, though. There aren't enough good command line utilities in AmigaOS, though many of the standard Unix complement have been ported and are available as third party software. |
