Question Shell Script for OS identification on all Platforms

Hi Mates,

I am writing a Shell script for identifying OS installed on the machine (it can Be any Unix like Solaris, AIX, RHEL, OEL, HP-UX ). With That I want to select appropriate software listed out in a file.

My Question here is, what are the appropriate flags to be used with "uname" command to accurately Identify OS and all necessary parameters like kernal (on all platforms), whoes entries I should maintain in the File along with software name.

I do not want to use "Uname -a"

Awaiting response from all.

Hi itkamaraj,

I can't, because
1. its not a common file across all platforms, neither the release files on all platform has common format.
2. I want to have specific information (in a tabular form) in a file.

Example data I want to have in a csv file is something like below. ( I am expecting right columns/uname flags which are valid accross all platforms and can be mentioned appropriately against software verision

#OS(uname -o),HWP(uname -i),KrnlRelse (uname -r),SOFTWARE_Setup_NAME

use uname with no arguments

Or use uname with the options specified in the POSIX standard. Those (with 99% certainty) will work on any Unix/-compatible platform.

How about starting with
uname -s


From there, based on the OS, run OS specific commands to get the information you need.
