Quickly discover the running Linux kernel release with a single command. 16.11.2025 | reading time: 2 min Want to know exactly which kernel is running on a system? Use `uname -r` to print the kernel release string so you can verify compatibility, debug issues, or prepare updates. One-line check Run the command `uname -r` in a shell and it returns the kernel release only, which is ideal for scripts and quick checks when a simple answer is required. Example session A short terminal example shows the command and its output exactly: ``` $ uname -r 5.15.0-76-generic ``` Dig deeper If more context is needed, use `uname -a` to show all system information or `uname -v` for the kernel build version; `uname -r` is best when you only need the release token for package matching, kernel-module checks, or automated inventory scripts. Other approaches Other ways to confirm kernel details include reading `/proc/version` with `cat /proc/version` for compiler and build-time data, `hostnamectl` on systemd systems for a friendly summary, or `dmesg` to inspect early boot kernel messages for version and configuration hints. Final note Checking the kernel release is a small habit that pays off during troubleshooting and deployments; keep exploring kernel tools and consider formalizing skills with certifications like CompTIA Linux+ or LPIC-1, and intensive exam preparation at bitsandbytes.academy to level up quickly.
