GNU sort has an option (-V) to sort by version number:
$ cat kernels
kernel-3.10.0-514.el7.x86_64
kernel-3.10.0-693.2.2.el7.x86_64
kernel-2.10.0-693.5.2.el7.x86_64
kernel-3.10.0-514.26.2.el7.x86_64
$ sort -V kernels
kernel-2.10.0-693.5.2.el7.x86_64
kernel-3.10.0-514.26.2.el7.x86_64
kernel-3.10.0-514.el7.x86_64
kernel-3.10.0-693.2.2.el7.x86_64
To get only the newest version, use tail:
$ sort -V kernels | tail -1
kernel-3.10.0-693.2.2.el7.x86_64
If you want the newest first, then sort in reverse order (-r):
$ sort -Vr kernels
kernel-3.10.0-693.2.2.el7.x86_64
kernel-3.10.0-514.el7.x86_64
kernel-3.10.0-514.26.2.el7.x86_64
kernel-2.10.0-693.5.2.el7.x86_64
If you are on MacOS, there is the option to install GNU tools with homebrew.
