How do we check the Linux machine OS?
I have IBM Z-Linux machine as well as RedHat Linux.

Where do I see that the particular machine is z-Linux?

below output from zlinux.
Code:
$ uname -a
Linux  xxxxxxxHostname 2.6.18-406.el5 #1 SMP Fri May 1 10:42:26 EDT 2015 s390x s390x s390x GNU/Linux

below output from redhat.
Code:
$ uname -a
Linux xxxxxxxHostname 2.6.32-504.16.2.el6.x86_64 #1 SMP Tue Mar 10 17:01:00 EDT 2015 x86_64 x86_64 x86_64 GNU/Linux

I see only difference is s390x s390x s390x . But this does not say that it is z-Linux. Can you please help me where to find the z-Linux info?

I think it is called z-linux because of the server it runs on. Note the title of this IBM page:

IBM z Systems - Linux on z Systems

IT is not clear to me why you need to see exactly linux-z - try cat /etc/release.

varies (and my knowledge is a few years old)... you might try:

Code:
cat /proc/sysinfo


Ok... that probably doesn't help much, but this might (this is old .... older mainframes and z):

Code:
sysinfo=`cat /proc/sysinfo'
ztype=`echo "$sysinfo" | sed -n 's/^Type:[ ]*\(.*\)/\1/p'`
                        zmodel=`echo "$sysinfo" | sed -n 's/^Model:[ ]*\(.*\)/\1/p'`
                        if [ "$ztype" -a "$zmodel" ]; then

                                productid="${ztype}-${zmodel}"
                                # Determine mainframe product
                                case "${ztype}" in
                                4381)

                        fi

YMMV if this gets you anywhere... this is from some work I did 3 years ago or so. Maybe IBM has a tool now... but at one time it really was this hard. Maybe somebody has something more contemporary....
