How to see the version of Oracle Linux
What version of Oracle Linux do I have?
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)
