4 Commands To Check Linux System Version

The following is the method to check whether your existing Linux is 64-bit or 32-bit, the purpose to know the Linux version is when you are about to install a certain software whether the software supports your Linux version or not. And additionally this will add more knowledge for us too.

The following is the commands to check your Linux system version:

Uname command

uname -i

The output:

  • x86_64 = 64-bit
  • i686 = 32-bit

uname is the command to view your system information, such as the Kernel version, operating system and others man uname.

Arch command

You can also run the arch command that will give the same result as using the uname -m command.

Getconf command

The simpler way and clear is using getconf command.

getconf LONG_BIT

The output:

  • 64 = 64 bit
  • 32 = 32 bit

lscpu command

The following is lscpu or command to show about information such as CPU architecture. But the OpenVZ VPS usually doesn’t support this command.

lscpu

The output—more or less—like this:

Architecture:        x86_64
