How to compare two strings in dot separated version format in Bash?

Question

Is there any way to compare such strings on bash, e.g.: 2.4.5 and 2.8 and 2.4.5.1?

Answer 1

if it's just about to know whether one version is lower than another I came up checking whether sort --version-sort changes the order of my version strings:

    string="$1
$2"
    [ "$string" == "$(sort --version-sort <<< "$string")" ]
