Linux command : uname

Recently, I came across a Linux command that I found really helpful and I am sure you’ll find it helpful as well, especially when you’d like to install something on your system and are in desperate need of information about the Operation System or the Linux distribution that you are using. The command that I was referring to is ‘uname’. This command prints almost all the information that you want about the system. Some of the very useful arguments of this command that I found are as follows :

1. The -a option gives the user, complete information about the system in the order : kernel name, node name, kernel release, kernel version, hardware name, processor type, hardware platform, operating system.

uname -a

2. The -m option displays whether you are running a 32 bit or 64 bit version of Linux distribution. ( If it is a 32 bit Linux distribution – i686 will get displayed as a result of running the following command, whereas if it is a 64 bit distribution, then x86_64. )

uname -m
