This article mainly introduces how to use the uname command, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

The uname command is used to print information about the current system (kernel version number, hardware architecture, host name, operating system type, and so on).

# unameLinux1. Kernel name

You can use the-s parameter to display the kernel name. (note: you can run this command on other Unix-like systems, for example, mac will display Darwin)

# uname-sLinux

The output information will be the same as when uname has no parameters.

two。 Kernel distribution

If you want to know which kernel distribution you are using (a different kernel package), you can use the-r parameter

# uname-r 2.6.18-371.1.2.el53. Kernel version

In addition to some kernel information, you can also get more detailed kernel version information with the-v parameter uname.

# uname-vault 1 SMP Tue Oct 22 12:57:43 EDT 20134. Node name

The parameter-n will provide you with the hostname of the node. For example, if your hostname is "dev-machine", the-n parameter prints the hostname.

# uname-ndev-machine

For RedHat and CentOS users, you can also view it through the / etc/redhat_release file:

# cat / etc/redhat_releaseCentOS release 5.10 (Final)

If it is not a RedHat-based distribution, you can check the / etc/issue file. Similar to the following:

# cat / etc/issueLinux Mint Olivia\ n\ lvl 5. Hardware name

If you want to know what kind of machine you are using, you can try the-m parameter. It will tell you about the hardware.

# uname-mi686

I686 indicates that you are using a 32-bit operating system, and if it is X86x64, it means you are using a 64-bit system.

6. Hardware platform

Similar to the hardware name, the-I parameter shows your hardware platform (hardware name i686 belongs to the hardware platform i386 series).

# uname-ii386

Similarly, i386 means that this is a 32-bit system running, and if the output is X86x64, then you are running a 64-bit system.

7. Processor Typ

You can use the-p parameter to see the processor type. If the uname is not recognized, it displays' unknown' as output.

# uname-pi6868. Operating system

Uname can also reveal the operating system you are running, and you can do this with the-o parameter.

# uname-oGNU/Linux9. All the information.

There is one parameter that displays all the information! This is the-a parameter, which displays all the information. If-I and-p are output to unknown, they are omitted by default.

# uname-aLinux dev-machine 2.6.18-371.1.2.el5 # 1 SMP Tue Oct 22 12:57:43 EDT 2013 i686 i686 i386 GNU/Linux Thank you for reading this article carefully.
