9 Linux Uname Command Examples To Get Operating System Details
|
||
================================================================================
|
||
|
||
|
||
When you are in console mode, there is no ‘Right click > About’ to give you information about your operating system. In Linux, you can use command **uname** to help you about that. Uname is the short name for **unix name**. Just type **uname** in console.
|
||
|
||
When you type uname without parameter, it will only show the name of your operating system.
|
||
|
||
# uname
|
||
Linux
|
||
|
||
It may not satisfy what you need. So you may need to use some parameters to make uname show the information you need.
|
||
|
||
Here’s the list of uname parameters :
|
||
|
||
### 1. Kernel name ###
|
||
|
||
To reveal the kernel name, you can use **-s** parameter.
|
||
|
||
# uname -s
|
||
Linux
|
||
|
||
The output will be same with uname without parameter.
|
||
|
||
### 2. Kernel release ###
|
||
|
||
If you need to know what kernel release you’re using, just use **-r** parameter
|
||
|
||
# uname -r
|
||
2.6.18-371.1.2.el5
|
||
|
||
### 3. Kernel version ###
|
||
|
||
Beside kernel information, uname can also fetch the kernel version. Use **-v** parameter for this purpose
|
||
|
||
# uname -v
|
||
#1 SMP Tue Oct 22 12:57:43 EDT 2013
|
||
|
||
### 4. Nodename ###
|
||
|
||
Parameter -n will give you the node hostname. For example, if your hostname is “dev-machine”, **-n** parameter will print dev-machine as the output of -n parameter
|
||
|
||
# uname -n
|
||
dev-machine
|
||
|
||
For RedHat and CentOS, you can also use **/etc/redhat_release** file :
|
||
|
||
# cat /etc/redhat_release
|
||
CentOS release 5.10 (Final)
|
||
|
||
For non-RedHat based distro, you may use **/etc/issue**. Here’s the example :
|
||
|
||
# cat /etc/issue
|
||
Linux Mint Olivia \n \l
|
||
|
||
### 5. Hardware name ###
|
||
|
||
If you are wondering what kind of machine you’re using, you can try **-m** parameter. It will show you information about it.
|
||
|
||
# uname -m
|
||
i686
|
||
|
||
i686 is indicates that your system is 32 bit operating system. While x86_64 means your system is a 64 bit system.
|
||
|
||
### 6. Hardware platform ###
|
||
|
||
Similar with hardware name, -i parameter will show you hardware platfrom.
|
||
|
||
# uname -i
|
||
i386
|
||
|
||
i386 mean you are running a 32 bit system. If the output is x86_64 it’s mean that you are running 64 bis system.
|
||
|
||
### 7. Processor type ###
|
||
|
||
To see processor type, you can use **-p** parameter. If uname is not able to show you that information, it will show you ‘unknown’ in the output.
|
||
|
||
# uname -p
|
||
i686
|
||
|
||
### 8. Operating system ###
|
||
|
||
Uname can also used to reveal what operating system you are running. Use **-o** parameter to fulfill this purpose.
|
||
|
||
# uname -o
|
||
GNU/Linux
|
||
|
||
### 9. All information ###
|
||
|
||
There is one parameter that can reveal all information. It’s **-a** parameter. It will show you all information **except omit -i and -p** if they are unknown.
|
||
|
||
# uname -a
|
||
Linux dev-machine 2.6.18-371.1.2.el5 #1 SMP Tue Oct 22 12:57:43 EDT 2013 i686 i686 i386 GNU/Linux
|
||
|
||
That’s the uname command in use. Please stay tuned to see more commands.
|
||
|
||
Thank you.
