There no universal standard, but the kernel is usually found in the /boot directory.

2You can use
uname -rto find out the version you're running and then look for a file in/bootwith that name. You can also usecat /proc/cmdlineto find the kernel path, but note that this path is relative to the root image at boot time, so/likely means/boot/in the running system. Commented Aug 17, 2012 at 8:17 -
1The path that the kernel reports that it was loaded from is relative to the root as it was at the time the kernel was loaded. That's probably called
/bootby the time the system is fully loaded. (After the kernel has been booted, the root is "pivoted" to the normal root and the boot time root is usually called/bootin the run-time filesystem.) Commented Aug 17, 2012 at 8:23 -
6Using cat /proc/cmdline is a better method because if you use the uname -r you will not be able to tell the difference between that kernel image or a rescue image built from the same kernel version.– user522266Commented Nov 15, 2015 at 20:16

Thanks for the answer. I found "/lib/modules/<version>/kernel" folder in my Ubuntu 18.04 OS computer. Does it also contain the information of kernel? Commented Oct 27, 2022 at 23:05
