9 Linux Uname Command Examples To Get Operating System Details
================================================================================
![](http://linoxide.com/wp-content/uploads/2013/11/linux-uname-command.png)
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.

九个用Linux uname 命令获取操作系统详情的实例
================================================================================
![](http://linoxide.com/wp-content/uploads/2013/11/linux-uname-command.png)
当你在控制台模式下,无法通过‘右击 > About’给予你关于操作系统的信息.在Linux下,你可以用**uname**命令,帮助你完成. Uname是**unix name**的缩写.让我们先在控制台键入**uname**.
当你输入uname不带参数时,它仅仅只显示你的操作系统的名字.
# uname
Linux
也许它不能满足你的需要.所以你需要用一些参数使uname显示所需信息.
以下是uname参数的列表:
### 1. 内核名称 ###
你可以用**-s**参数,显示内核名称.
# uname -s
Linux
输出信息会跟uname不带参数时输出的一样.
### 2. 内核发行版 ###
如果你想知道你正在使用那个内核版本,就可以用**-r**参数
# uname -r
2.6.18-371.1.2.el5
### 3. 内核版本 ###
除一些内核信息外,用**-v**参数uname也能获取更详细的内核信息.
# uname -v
#1 SMP Tue Oct 22 12:57:43 EDT 2013
### 4. 节点名 ###
参数 -n 会提供给你节点的主机名.举例来说,如果你的主机名是“dev-machine”,**-n**参数会打印用-n参数的输出.
# uname -n
dev-machine
对于RedHat和CentOS用户来说,你也可以通过**/etc/redhat_release**文件:
# cat /etc/redhat_release
CentOS release 5.10 (Final)
如果不是基于RedHat的发行版,你可以用**/et/issue/**文件.类似如下:
# cat /etc/issue
Linux Mint Olivia \n \l:
### 5.硬件名称 ###
如果你在疑惑用的是那类机器,你可以尝试**-m**参数.它将告诉你关于硬件的信息.
# uname -m
i686
i686表明了你用的是32位的操作系统.如果是X86_64则表明你用的是64位的系统.
### 6. 硬件平台 ###
类似与硬件名称, -i参数会显示你的硬件平台.
# uname -i
i386
i386意味这是正在运行一个32位的系统.如果输出的是X86_64则说明你正在运行一个64位的系统.
### 7. 处理器类型 ###
你可以用**-p**参数查看处理器类型.如果uname无法识别,它会显示 ‘unknown’ 的输出.
# uname -p
i686
### 8. 操作系统 ###
Uname也可以透露你在运行的操作系统.用**-o**参数可以实现这个目的.
# uname -o
GNU/Linux
### 9. 所有信息 ###
有一个参数可以展示所有的信息!.这就是**-a**参数.它会显示所有信息,如果**-i和-p**输出为unknown则默认会被省略.
# 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
以上就是关于uname命令的使用.请敬请期待更多的命令!
谢谢!
