How to find out what version of RHEL I'm using?
if grep -q -i "release 6" /etc/redhat-release
then
echo "running RHEL 6.x"
fi
This would be the simplest way I can think of.
You can also use the lsb_release
command. If you're already certain it's RHEL, getting the major version number is:
majversion=$(lsb_release -rs | cut -f1 -d.)
Use rpm -q redhat-release-server
The /etc/redhat-release
file could have been edited by an admin looking to install third party software without performing an actual OS upgrade.
