How to Check RHEL Linux Version
In the world of Linux distributions, Red Hat Enterprise Linux (RHEL) stands out as a robust and reliable choice for businesses and organizations. Whether you are a system administrator or a developer, knowing the version of RHEL you are working with is crucial for managing and troubleshooting your system effectively. In this article, we will discuss various methods to check the RHEL Linux version, ensuring that you have the necessary information at your fingertips.
Using the ‘cat’ Command
One of the simplest ways to check the RHEL Linux version is by using the ‘cat’ command to display the contents of the ‘/etc/redhat-release’ file. This file contains the distribution’s version information. To do this, open a terminal and type the following command:
“`
cat /etc/redhat-release
“`
The output will display the RHEL version, along with other details such as the release date and architecture.
Using the ‘lsb_release’ Command
Another method to check the RHEL Linux version is by using the ‘lsb_release’ command, which provides detailed information about the Linux distribution. To get the version, open a terminal and type:
“`
lsb_release -a
“`
This command will display a list of attributes, including the release identifier, codename, description, and more. Look for the ‘Release’ attribute to find the RHEL version.
Using the ‘rpm’ Command
The ‘rpm’ command is a powerful tool for managing packages on RHEL. To check the version, use the following command:
“`
rpm -q –queryformat ‘%{version}’ redhat-release
“`
This command will output the version of the ‘redhat-release’ package, which corresponds to the RHEL version.
Using the ‘yum’ Command
The ‘yum’ command is another way to check the RHEL Linux version. Open a terminal and type:
“`
yum info redhat-release
“`
This command will display detailed information about the ‘redhat-release’ package, including the version number.
Conclusion
Knowing the RHEL Linux version is essential for managing and troubleshooting your system. By using the methods outlined in this article, you can quickly and easily determine the version of RHEL you are working with. Whether you prefer using the ‘cat’ command, ‘lsb_release’ command, ‘rpm’ command, or ‘yum’ command, these tools provide a reliable way to check your RHEL version and ensure your system is up-to-date and functioning correctly.
