To view the CentOS version, you can use the following command:
cat /etc/ centos-release
This command displays your CentOS version number and name. For example, if you run CentOS 7, it may display an output similar to "CentOS Linux release 7.9.2009 (Core)".
In addition, you can view the operating system kernel version by running one of the following commands:
uname -r
perhaps
uname -a
These commands will display the current kernel version and complete system information respectively.
Please note that when viewing the version information, ensure that you have sufficient permissions to execute relevant commands, and that you are running the correct operating system version.
