How to show CentOS Version in different commands?
I have listed all the types of commands here. Use all the below tricks and get CentOS Version for other operations.
Method 1: Use uname command
An easy way to inspect the Kernel version is by using Uname known as Unix name. You can easily get all the information (user name, kernel version and much more) about your working system by uname command.
Output will be as follows,
Linux office.ubuntumag.net 2.6.32-220.2.1.el6.x86_64 #1 SMP Fri Dec 23 02:21:33 CST 2011 ×86_64 ×86_64 ×86_64 GNU/Linux
Get further information using the below uname commands…
|-a, –all||print all information|
|-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|
You can also check the System architecture details by using # uname -m
Method 2: Check using rpm command
# rpm --query centos-release centos-release-7-1.1503.el7.centos.2.8.x86_64
Method 3: Check using Hostnamectl command
You can just configure your host name and its associated settings by using this hostnamectl command.
Host name $ hostnamectl
— OR —
$ hostnamectl status
Static Host Name is saved in Kernel. It can be viewed by
Copy & paste the below hostnamectl code
# hostnamectl Static hostname: localhost.localdomain Icon name: computer-laptop Chassis: laptop Machine ID: 6892999b8d8c43fab29fca961dbff24b Boot ID: b0a95bf56f61417ca8073b3847a73ab1 Operating System: CentOS Linux 7 (Core) CPE OS Name: cpe:/o:centos:centos:7 Kernel: Linux 3.10.0-229.7.2.el7.x86_64 Architecture: x86_64
Method 4: Check using cat command
To show Kernel information for the running machine, Use the below code to know get your version correctly.
# cat /etc/centos-release CentOS Linux release 7.1.1503 (Core) # cat /etc/os-release NAME="CentOS Linux" VERSION="7 (Core)" ID="centos" ID_LIKE="rhel fedora" VERSION_ID="7" PRETTY_NAME="CentOS Linux 7 (Core)" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:centos:centos:7" HOME_URL="https://www.centos.org/" BUG_REPORT_URL="https://bugs.centos.org/" CENTOS_MANTISBT_PROJECT="CentOS-7" CENTOS_MANTISBT_PROJECT_VERSION="7" REDHAT_SUPPORT_PRODUCT="centos" REDHAT_SUPPORT_PRODUCT_VERSION="7"
# cat /etc/redhat-release CentOS Linux release 7.1.1503 (Core)
# cat /etc/system-release CentOS Linux release 7.1.1503 (Core)
Check the following commands to show CentOS Version Numbers:
Method 5: Check using lsb_release command
Lsb_release command is a portion of Red Hat called as redhat-lsb package. Your system will not have “Linux Standard Base” command by default.
lsb_release – to show Distribution Specific Information.
Use some alternative tactics to check CentOS version by lsb_release command as follows:
# lsb_release -d
Description: CentOS Linux release 7.1.1503 (Core)
You can also use the below command for checking Kernel version using lsb command.
Install lsb packages by Red Hat from its base warehouse by using the below code.
# yum install redhat-lsb-core
— OR —
# yum install redhat-lsb
Now use this below command for showing CentOS version
# lsb_release -a LSB Version: base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch Distributor ID: CentOS Description: CentOS release 6.4 (Final) Release: 6.4 Codename: Final
That’s it. Hope you got all the information from your kernel. If you have any other ideas and allusions feel free to comment us below…
