To find the operating system name or release version in Linux, you can use the cat, lsb_release, or hostnamectl commands.
Using the cat command:
The cat command can be used to read the contents of a file. To find the operating system name, you can use the following command:
cat /etc/os-release
This will print the contents of the /etc/os-release file, which contains information about the operating system, including the name and release version.
Using the lsb_release command:
The lsb_release command is a tool that provides information about the Linux Standard Base (LSB) compliance of a Linux system. To find the operating system name, you can use the following command:
lsb_release -a
This will print a variety of information about the operating system, including the name, release version, and distributor.
Using the hostnamectl command:
The hostnamectl command is used to manage the system hostname, but it can also be used to print information about the operating system. To find the operating system name, you can use the following command:
hostnamectl
This will print a variety of information about the system, including the hostname, operating system name, and operating system ID.
All three of these methods will provide you with the operating system name and release version. The best method for you will depend on your personal preference.
