Tutorial: How to Get the Linux Version From the Command Line

By: Jeremy Morgan






There are several ways to get your Linux version from the command line. One way that just displays a basic name:

uname

But this usually just returns “Linux”. Pretty sure you already knew that. A more detailed view would be:

uname -a

Which shows “all” the information uname provides.

Here are some other switches for uname:

  -a, --all                print all information, in the following order,
except omit -p and -i if unknown:
-s, --kernel-name        print the kernel name
-n, --nodename           print the network node hostname
-r, --kernel-release     print the kernel release
-v, --kernel-version     print the kernel version
-m, --machine            print the machine hardware name
-p, --processor          print the processor type or "unknown"
-i, --hardware-platform  print the hardware platform or "unknown"
-o, --operating-system   print the operating system
--help     display this help and exit
--version  output version information and exit

There is another method for gathering system information:

cat /proc/version

This will also show you quite a bit of information on your system.

Linux version 2.6.32-71.el6.x86_64 (mockbuild@x86-007.build.bos.redhat.com)
(gcc version 4.4.4 20100726 (Red Hat 4.4.4-13) (GCC) ) #1 SMP Wed Sep 1 01:33:01 EDT 2010

Some distros have their own methods of identification also, such as RedHat:

cat /etc/redhat-release

Consult your manuals for each distro to find out where they store this information.
