How to see the version of Oracle Linux
Determine Oracle Linux version
Oracle Linux is based on Red Hat Enterprise Linux. At first, it may be confusing to determine what specific operating system is running. This is because both have the /etc/redhat-release file.
If that file exists, use the
cat command to display the contents. Next step is to determine if there is a /etc/oracle-release file as well. If so, then you can be sure that Oracle Linux is running.
Sample output might be: Oracle Linux Server release 6.7
Next time when you are on a system and not sure what it is running, use this:
ls -l /etc/*-release
This shows you any files that might give a hint on the operating system version.
- /etc/enterprise-release (older versions of OEL)
