The objective of this guide is to provide you with some hints on how to check system version of your Redhat Enterprise Linux (RHEL). There exist multiple ways on how to check the system version, however, depending on your system configuration, not all examples described below may be suitable. For a CentOS specific guide visit How to check CentOS version guide.
Privileged access to to your RHEL system may be required.
- # – requires given linux commands to be executed with root privileges either directly as a root user or by use of
- $ – requires given linux commands to be executed as a regular non-privileged user

hostnamectl is most likely the first and last command you need to execute to reveal your RHEL system version:
$ hostnamectl Static hostname: localhost.localdomain Transient hostname: status Icon name: computer-vm Chassis: vm Machine ID: d731df2da5f644b3b4806f9531d02c11 Boot ID: 384b6cf4bcfc4df9b7b48efcad4b6280 Virtualization: xen Operating System: Red Hat Enterprise Linux Server 7.3 (Maipo) CPE OS Name: cpe:/o:redhat:enterprise_linux:7.3:GA:server Kernel: Linux 3.10.0-514.el7.x86_64 Architecture: x86-64
Query Release Package
rpm command to query Redhat’s release package:
RHEL 7 $ rpm --query redhat-release-server redhat-release-server-7.3-7.el7.x86_64 RHEL 8 $ rpm --query redhat-release redhat-release-8.0-0.34.el8.x86_64
Common Platform Enumeration
Check Common Platform Enumeration source file:
$ cat /etc/system-release-cpe cpe:/o:redhat:enterprise_linux:7.3:ga:server
Depending on whether a
redhat-lsb package is installed on your system you may also use
lsb_release -d command to check Redhat’s system version:
$ lsb_release -d Description: Red Hat Enterprise Linux Server release 7.3 (Maipo)
redhat-lsb package with:
# yum install redhat-lsb
Check Release Files
There are number of release files located in the /etc/ directory. Namely
$ ls /etc/*release os-release redhat-release system-release
cat to check the content of each file to reveal your Redhat OS version. Alternatively, use the below for loop for an instant check:
$ for i in $(ls /etc/*release); do echo ===$i===; cat $i; done
Depending on your RHEL version, the output of the above shell for loop may look different:
===os-release=== NAME="Red Hat Enterprise Linux Server" VERSION="7.3 (Maipo)" ID="rhel" ID_LIKE="fedora" VERSION_ID="7.3" PRETTY_NAME="Red Hat Enterprise Linux Server 7.3 (Maipo)" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:redhat:enterprise_linux:7.3:GA:server" HOME_URL="https://www.redhat.com/" BUG_REPORT_URL="https://bugzilla.redhat.com/" REDHAT_BUGZILLA_PRODUCT="Red Hat Enterprise Linux 7" REDHAT_BUGZILLA_PRODUCT_VERSION=7.3 REDHAT_SUPPORT_PRODUCT="Red Hat Enterprise Linux" REDHAT_SUPPORT_PRODUCT_VERSION="7.3" ===redhat-release=== Red Hat Enterprise Linux Server release 7.3 (Maipo) ===system-release=== Red Hat Enterprise Linux Server release 7.3 (Maipo)
The least reliable way on how to check Redhat’s OS version is by looking at Grub configuration. Grub configuration may not produce a definitive answer, but it will provide some hints on how the system booted.
The default locations of grub config files are
grep command to check for
# grep -w menuentry /boot/grub2/grub.cfg /etc/grub2.cfg
An another alternative is to check the value of the “GRUB Environment Block”:
# grep saved_entry /boot/grub2/grubenv saved_entry=Red Hat Enterprise Linux Server (3.10.0-514.el7.x86_64) 7.3 (Maipo)
