Full Discussion: Which OS Binary was build
Homework and Emergencies Emergency UNIX and Linux Support Which OS Binary was build Post 302413857 by gaurav1086 on Saturday 17th of April 2010 05:28:11 PM

Hello,

you can check the dependancy libraries which can distinguish the binaries

Code:
ldd binary_file

If their versions match that of the current version of the libs.

apparently you can check out the external libs they are using another way too.
Code:
 nm -o binary_file | grep '\bU\b'

The binary file alone cannot give you the information about which version of gcc was used to build it.

If there is a difference b/w the kernel version they are using then you can check the binaries that are made for 2.4 or 2.6 . I suppose redhat-6.2 uses 2.4 while rhel uses 2.6.18.

example :

Code:
 file a.out
a.out: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.8, not stripped

So it lists 2.6 on mine

So in order to distinguish you can rename all lthe binaries depending on the kernel version to later distinguish them

Code:
#!/bin/bash

for fil in $DIR/*;do if file $fil | grep -q '2.6' ;then echo "2.6-${fil}";else echo "2.4-${fil}";fi;done

Apparently you can rename the files with the kernel version to find out which OS it was built.

Hope this helps,

Regards,
gaurav.

subscription-manager-gui(8)				       Subscription Manager				       subscription-manager-gui(8)

NAME

       subscription-manager-gui - Launches the UI client of the Subscription Manager.

SYNOPSIS

       subscription-manager-gui [--register]

DESCRIPTION

       subscription-manager-gui  opens	the  local client tool to manage subscriptions and installed products on Red Hat Enterprise Linux systems.
       The same tasks that can be performed by invoking subscription-manager can be performed in the GUI, including  registering  systems  with  a
       subscription management service, applying and removing subscriptions, and viewing the subscription status of installed products.

       The Subscription Manager UI can also be opened by selecting the Red Hat Subscription Manager item from the Applications > System Tools menu
       in RHEL 5.x or the System > Administration menu in RHEL 6.x.

OPTIONS

       --register
	      If a system has not yet been registered, then the GUI registration page can be opened immediately, as the Subscription  Manager  GUI
	      comes up. This is only relevant for unregistered systems; if this is used after a system is registered, the option is ignored.

REFERENCES

       For  procedures	and  tasks that can be performed in the Subscription Manager UI, check the Gnome help files (by pressing <F1>) or refer to
       the RHEL Subscription  Management  Guide  at  <https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Subscription_Management/1.0/html/Sub-
       scription_Management_Guide/index.html>.
