Hi,
I need a way to get the distribution release information on AIX machine.We have a file /etc/fedora-release for fedora and /etc/redhat-realease for RedHat.Please can anyone help me out with a solution.

Thanks to all those people who have spend their time reading this query and sorting out a solution for this.I have found the answer for this.The command oslevel -r give the distribution release information on AIX machine

Hello Afrose_fathima,

The best commandto use for that is instfix -i | grep ML this will tell you if you have a complete istall of a certian maintence level.

And if you take the output of the above command and use:

instfix -ciqk <LEVEL_STRING> | grep :-:

you will get a list of filessets still below that release level

instfix -ciqk <LEVEL_STRING> | grep :+:

you will get a list of filessets above a release level

oslevel -r doesnt report on files that are 'above' level.

The convention for the the oslevel -r output, and the keyword for instfix is:

$ oslevel -r
5200-07

instfix -ciqk 5200-07_AIX_ML | grep :+:
5200-07_AIX_ML:bos.rte.lvm:5.2.0.75:5.2.0.76:+:AIX 5200-07 Update
5200-07_AIX_ML:devices.pci.ad100501.rte:5.2.0.75:5.2.0.76:+:AIX 5200-07 Update

btw. to see the filessets in a level use:
instfix -ciqk 5200-07_AIX_ML

(you might want to add a awk script to print the second argument)
