Have a look on IPC::Run - it might do just what you need to do.

Sorry if my advice was wrong.

    Thanks...this looks exactly like what I need, however, I do not have that module on my system and I would need to go through system support to it - I know I can install it without sys admin but this script is to go to clients servers and this would be a difficult task to ask of clients to install this module.

    If this is my only option, I do have ActiveState's Perl Dev Kit which allows me to build individual executables for the 5 platforms we support - Windows, Solaris, HP Linux, and AIX. But I believe I would have to install the Dev Kit on each of the platforms to do that.

      Another option is IPC::Open2, which is in core. This will require a bit more code, but should work:

      use IPC::Open2; open IN, "<", "commandfile"; # unfortunately, scalar filehandles won't + work this way open OUT, ">", "logfile"; my $pid = open2(">&OUT", "<&IN", "theprogram"); waitpid $pid, 0;

      You can also package your application together with module you use with the help of PAR::Packer (its installation is required only on the packager's computer). But I don't know whether it will interfere with PDK or not.

      Sorry if my advice was wrong.
