System Information

oslevel     # Report system version
oslevel -rq # Report "technology level" (major release?)
            # information
oslevel -sq # Report service pack information

Different system components (“filesets”) can be at different technology levels / service packs. You can list which software that is more (-g) or less (-l) recent than a given technology level (-r) or service pack (-s); for example:

oslevel -s -l $SERVICE_PACK # List filesets below the specified
                            # service pack

Fileset Information

lslpp -l               # List all filesets
lslpp -h $FILESET_NAME # Detailed fileset information

Some versions of AIX can also apparently use the RPM package manager.
