maskull has asked for the wisdom of the Perl Monks concerning the following question:

Hello. The cluster is two nodes running Solaris 10. From within a Perl script I need to detemine which is the active node. Optionally, determine whether the script is being run from the active node. Hope there is someone who can figure this one out, thanks!

    maskull,

    I saw your question earlier, but since no one has commented, I'll take a shot!

    I haven't used a Solaris system in 10+ years, but on other *nix systems, I would use:

    my @results = qx/ . . . /;
    Whatever system command you would use on the console, you can issue via 'qx' and it will give you the answer. In this context, I'm using the array @results, so you can get multiple lines of output. And, as usual there are multiple ways of doing this.

    Good Luck!
