Please don't make substantial changes to your original posts in a way that makes answers you already received not make sense anymore. Instead, add an addendum to your post to clarify.

Now, that said, what exactly is it you want to do now? You've got a list of version numbers and a version you want to match against them, and you want to run a particular script unless that version is on your list. So why not simply do exactly that in Perl?

foreach (@versions) {
    unless($_ eq $version) {
        runscript(...);
    }
}
[download]

Or, more idiomatically:

runscript(...) foreach (grep { $_ ne $version } @versions);
[download]

Sorry for updating the question at random. By the time I went clear on my problem statement there was an reply.

Basically I am looking for a generic solution that if the version string matches with the version I am looking then run a flow in the script else skip it.

So having a look up array will not help as there can any version in that format in future I need to update the array every time. That I don't want.

I'm sorry, but I don't understand what problem you're having, or in fact what you're trying to achieve. Could you clarify? Remember, you know what you mean, but we don't -- we can't read your mind, and we can't guess exactly what you're trying to achieve.
