AIX operating system

Advanced Interactive eXecutive (AIX) is the brand name of International Business Machines s proprietary UNIX operating system. It initially stood for Advanced IBM Unix internally, but probably the name was not approved by the legal department and was subsequently changed to Advanced Interactive eXecutive .

Some of AIX s more popular features include commands such as chuser, mkuser, rmuser, and similar things which allow for user administration analogous to file administration. AIX s level of support for logical volume management is gradually being added to the various free software Unix-like operating systems.

As of AIX 5L 5.3, the operating system will scale as follows:

64 Central processing unit

2 TeraByte main Random access memory

JFS2: 16 TB maximum supported file system

JFS2: 16 TB maximum supported Computer file size

=Release history=

Several different versions of AIX have existed over time, some being eventually eliminated. AIX V1, which ran on the IBM RT/PC (AIX/RT) appeared in 1986. It was based on System V Release 3. Since 1989, AIX has been the OS for the RS/6000 line of workstations and servers (AIX/6000). During AIX development, features from 4.2BSD and 4.3BSD were merged in by IBM and Interactive Systems Corporation (under contract to IBM).

=Interfaces=

==Graphical==

The Common Desktop Environment (CDE) is the default graphical user interface in AIX systems. As part of Linux Affinity and the free AIX Toolbox for Linux Applications (ATLA), open-source KDE and GNOME desktop are also available.

==Text Based==

SMIT, also known as smitty, is a text based System Management Interface Tool for AIX. It allows a user to navigate a menu hierarchy of commands, rather than using the command line. Experienced system administrators make use of the F6 command which generates the command line needed for complex tasks.
