amt35 has asked for the wisdom of the Perl Monks concerning the following question:

I have to modify somebody's Perl Script this morning and I don't know a lot about Perl.

I need to execute a windows .exe from within the Perl script with 3 parameters. Does anybody know the command I would use to do that? Also, the command needs to block the script from executing/going any further until the executable it started terminates.

Thanks,
Andrew

    You can use 
    $exitcode = system('path/to/your/file.exe arg1 arg2');

    It will run the EXE, it will wait until it completes, AND you'll get the exit status...

      $exitcode = system('path/to/your/file.exe arg1 arg2');
$exitcode = $exitcode >> 8;

      see system for details.

      I thought that "system" command work only in *nix OS, Do it work in Win OS as well ?

      Mosh.

        Yes, it works ;-)

    another possible solution is using backticks, and get the output back from the system:
    my $blah =  `echo hello world`;
print $blah;
