 How to find the version of a Linux kernel

Environment

ITMS 8.x

Resolution

Following are five distinct ways to find the kernel version on a linux box: 

  1. uname -r
  2. cat /proc/version
  3. rpm -q kernel
  4. dmesg | grep -i "linux version"
  5. ls /boot (this displays several files with version in the file name)

Sample results: 

# uname -r

2.6.18-8.el5

 

# cat /proc/version
