    perl -V:usethreads

    will tell you that.

    Also see Config.pm, which has the same information:

    use Config '%Config'; print $Config{ usethreads };

    A conceptual problem with your question may be that you think that only certain version numbers of Perl come threaded or unthreaded. This is a misconception. Perl can be built with or without threads in any version number starting since 5.6 (or even earlier). Whether you have threads available depends on the person who built your Perl binary and whether they enabled that option or not.

      Hi
      Well, I am usnig perl 5.8.8 which I think is single threaded. But I want to move to a multi-threaded perl version. Can you please confirm if perl 5.10 is multithreaded or not ? Or multi-threading is supported in 5.8.8 as well ?
      Consider that threads are enabled in the perl binary.

        5.8.8 can be multi-threaded; it depends on how it was compiled.

        5.10.x can be single-threaded; it depends on how it was compiled.

        Run this command on your machine and post the output: perl -V
