Identifying the OS

English Programming/Scripting
#1

I have a script I want to run only on openSUSE 11.1. So I include this bit of code in the script:

VERCHECK=`grep 11.1 /etc/SuSE-brand > /dev/null; echo $?`
if  "$VERCHECK" -eq "1" ]; 
  exit 1
fi

…so the script exits if the string “11.1” is NOT found in that file.

Two questions. The SUSE-brand file actually contains the contents

openSUSE
VERSION = 11.1

How would one go about checking for both lines in a single test. I know, in other words that I could grep for “openSUSE” and then, if that succeeds, nest another grep for “11.1”. But if I didn’t want to nest grep tests?

Secondly, and a bit cheekily I realise, but what are the exact contents of the equivalent file on Suse Enterprise Linux, please (if anyone here knows, of course!)?

Thanks in advance for any help offered.

You could instead look at /etc/SuSE-release which contains this:

openSUSE 11.1 (x86_64)
VERSION = 11.1

on a 64-bit machine for example. Both the distro and version are on the first line.

Wonderful advice. I looked in the /etc directory until my eyes went square… and they obviously did! Thank you for that.

Do you, by any chance, happen to know the contents of the SLES equivalent of that file?? No worries if not: you’ve already helped alot!

Ask in the SLES forum perhaps?

/etc/SuSE-release from SLES 10 SP2 x86_32:

ab@mybox0:~> cat /etc/SuSE-release
SUSE Linux Enterprise Server 10 (i586)
VERSION = 10
PATCHLEVEL = 2

and from SLES 11 x86_64

ab@mybox1:~> cat /etc/SuSE-release
SUSE Linux Enterprise Server 11 (x86_64)
VERSION = 11
PATCHLEVEL = 0

ab@mybox1:~> cat /etc/SuSE-brand
SLES
VERSION = 11
CO-BRANDS = SLE openSUSE

But yes, this is a good question for the SLES forums specifically in the
future.

Good luck.

Am very grateful for the SLES information (and, as I said, I realise I was being a bit cheeky). Great to know, anyway!

Thank you everyone.
