String match version format

Question

I want to let users select multiple layers of folders.

Once they select a version folder (Folder name similar as: 1.0.0) I will continue to do next steps.

How can I match the format like 1.0.0?

You can use regular expressions:

folderName="1.2.3";
matchPattern="^[0-9]\.[0-9]\.[0-9]$";

# if regex match, execute the command after "&&"
[[ $folderName =~ $matchPattern ]] && echo "Folder name matches pattern"
