I have the following content under
/lib/modules$ du -hs * | sort -hr | head -n 2055M 4.14.50-v7+55M 4.14.48-v7+55M 4.14.29-v7+54M 4.9.59-v7+54M 4.9.35-v7+54M 4.14.50+54M 4.14.48+53M 4.9.59+53M 4.9.35+53M 4.14.29+
Look like these are modules for different kernels? How can I determine kernel version without running OS (just looking and image file content)? Can I delete directories, others that mine?
