The Kernel#
1. How to check the kernel version of a Linux system?#
uname commend print system infomation
Run:
uname -a # print all information
uname -r # print the kernel release
uname -v # print the kernel version
2. List installed kernels#
Run:
xbps-query -l | grep linux
or
ls /boot
3. Remove older kernels#
sudo xbps-remove -R linux6.6-6.6.21_1 linux6.6-6.6.77_1 linux6.12-6.12.13_1
or
sudo rm config-6.12.23_1 initramfs-6.12.23_1.img vmlinuz-6.12.23_1
4. Update GRUB (if using GRUB)#
After removing old kernels, update GRUB so it doesn’t list them:
sudo xbps-reconfigure -f grub
or
if you are using grub-mkconfig:
sudo grub-mkconfig -o /boot/grub/grub.cfg
