AIX
Updated: 09/12/2023 by Computer Hope
AIX is short for advanced interactive executive and was first entered into the market by IBM in 1986. AIX is an implementation of Unix derived from both AT&T Unix System V and 4.3 BSD (Berkeley Software Distribution). AIX offers the Korn (ksh) shell, Bourne (sh) and C (csh) shells; however, it defaults to the Korn shell.
AIXL (AIX 5L) is IBM's key element to IBM's AIX / Linux affinity strategy. IBM is working to implement Linux API (application programming interface) compatibility within AIX and deliver a common set of application development tools and utilities across AIX and Linux.
