What version of RHEL?
Raw
gistfile1.txt
If you know you are on RHEL or Centos what are the ways to determine
which version you are on?
Well it depends upon why you want to know. Most reciently i wanted to automatically
choose the correct version of EPEL to install. I chose to use
yum version | grep '^Installed: ' | sed -e 's!^Installed:[ \t]\+\([^ \t/]\).*$!\1!'
other possibilities, instead of yum were:
rpm -q --queryformat '%{VERSION}' -f /etc/redhat-release
rpm -q --queryformat '%{VERSION}' --whatprovides redhat-release
