How To Check Ibm Installation Manager Version In Linux

When you install a Linux distribution on your own, you know which distribution and version it is.

Simply if y'all use SSH to log in to a remote Linux server provided by an enterprise or customer, you may wonder which Linux distribution and version information technology is.

The simplest manner to check Linux version is to see the content of the /etc/os-release file:

            cat /etc/os-release

It will bear witness an output similar to this:

            Proper noun="Ubuntu" VERSION="twenty.04.1 LTS (Focal Fossa)" ID=ubuntu ID_LIKE=debian PRETTY_NAME="Ubuntu 20.04.1 LTS" VERSION_ID="20.04" HOME_URL="https://www.ubuntu.com/" SUPPORT_URL="https://help.ubuntu.com/" BUG_REPORT_URL="https://bugs.launchpad.cyberspace/ubuntu/" PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy" VERSION_CODENAME=focal UBUNTU_CODENAME=focal

As you tin run into, the Linux name is Ubuntu and the version is 20.04.1.

However, that's not the only way to know the Linux distribution details. In this beginner's tip, I'll show y'all dissimilar ways to check which Linux you are running.

Detect Linux distribution details

Method one: Apply /etc/os-release file

If you are familiar with the Linux directory construction, yous probably already know that /etc directory contains the cadre configuration files of the system.

The bone-release file in the /etc directory keeps the information near the Linux distribution. Information technology gives you the distribution proper name, distribution version, release name or ID.

You can use true cat command to view the content of the file in Linux terminal:

            true cat /etc/os-release

Hither'southward what it displays for Alpine Linux server running on Linode infrastructure.

            handbook:~# cat /etc/os-release  NAME="Alpine Linux" ID=alpine VERSION_ID=3.12.0 PRETTY_NAME="Alpine Linux v3.12" HOME_URL="https://alpinelinux.org/" BUG_REPORT_URL="https://bugs.alpinelinux.org/"

As you tin see, the proper name of Linux distribution is Alpine Linux and the distribution version is 3.12.

The content of the /etc/os-release is usually unlike for different distributions. Distributions often use it to provide additional information like where to go support or file bugs etc.

For instance, the /etc/os-release provides more lines for CentOS Linux.

            NAME="CentOS Linux" VERSION="8 (Core)" ID="centos" ID_LIKE="rhel fedora" VERSION_ID="eight" PLATFORM_ID="platform:el8" PRETTY_NAME="CentOS Linux 8 (Core)" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:centos:centos:8" HOME_URL="https://www.centos.org/" BUG_REPORT_URL="https://bugs.centos.org/"  CENTOS_MANTISBT_PROJECT="CentOS-8" CENTOS_MANTISBT_PROJECT_VERSION="eight" REDHAT_SUPPORT_PRODUCT="centos" REDHAT_SUPPORT_PRODUCT_VERSION="8"

Even so, all of them provide the Linux distribution name and version then it is a pretty reliable fashion to know which Linux you are running. In fact, information technology is the most reliable way.

Method 2: Utilise hostnamectl command

Most Linux distributions these days use systemd. On such a system, you tin can use the hostnamectl control to get Linux version detail.

            hostnamectl

For the same CentOS system that you saw above, hostnamectl provides the post-obit details:

            [[email protected] ~]# hostnamectl     Static hostname: localhost.localdomain Transient hostname: li2498-99.members.linode.com          Icon proper noun: calculator-vm            Chassis: vm         Car ID: e3fe2be3e17be3e1763bf43e8337e68b            Boot ID: 33d3052bbffd44b1869bbffd4b00d26c     Virtualization: kvm   Operating System: CentOS Linux 8 (Core)        CPE Os Name: cpe:/o:centos:centos:viii             Kernel: Linux 4.18.0-147.viii.1.el8_1.x86_64       Architecture: x86-64

You can see the Linux version detail in the line starting with 'Operating System'.

The hostnamectl command is primarily used for dealing with the hostname but if information technology provides other details why not use it?

Method 3: Utilize lsb-release command

This is NOT a command that y'all'll detect in all Linux distributions. I think it is more often than not used by Debian/Ubuntu based distributions.

You can use the lsb_release control with option -a and it will provide distribution details:

            lsb_release -a

Don't mind the No LSB modules are available line. It'south not an error of whatever kind.

            [email protected]:~$ lsb_release -a No LSB modules are bachelor. Benefactor ID:	Ubuntu Clarification:	Ubuntu twenty.04.1 LTS Release:	20.04 Codename:	focal

Bonus Tip: Find Linux kernel version

Now that you know which distribution you lot are running, perhaps you would too like to know near the Linux kernel version running on the system.

You can get the kernel details using the uname command in any Linux distribution.

            uname -r

The output shows only the Linux kernel version:

            handbook:~# uname -r five.4.43-1-virt

No prizes for guessing that the in a higher place system is running on Linux kernel version 5.4.43.

I hope y'all find this quick tip helpful in finding Linux version detail. If you have questions or suggestions, delight let me know in the comment section.
