Check Your Kali Linux Version

Why check

Kali Linux is a Debian-based system for security testing. It updates often, so it helps to know which release you use. The version tells you which tools and fixes you have.

Method 1: lsb_release

lsb_release -a

The output lists the distributor, description and release number.

Method 2: os-release file

cat /etc/os-release

Find VERSION and VERSION_ID.

Method 3: uname

uname -a

This shows the kernel and architecture. It does not show the Kali release number.

Method 4: hostnamectl

hostnamectl

You get the operating system name and the kernel version.

Method 5: /proc/version

cat /proc/version

It shows build details of the running kernel.

Method 6: neofetch or screenfetch

These tools print a colorful summary of your system, including the Kali version:

sudo apt install neofetch screenfetch
neofetch

Keep Kali up to date

sudo apt update && sudo apt upgrade -y

This refreshes the package lists and upgrades all installed packages.

Quick recap

• lsb_release -a and cat /etc/os-release show the release.
• uname and /proc/version show the kernel only.
• Update often with apt.
