How to use the shell to determine the size of a version number

If you want to compare two version number strings through the shell, such as two version numbers 1.1.2 and 1.2.1 Two versions who are relatively new.

The simplest is to use the sort command. With the parameter "-V" the sort command can sort the version numbers in the text (by default, the ascending sort), and then you want to sort in reverse order, then use the parameter "-RV".
