in reply to Run a shell command in a new terminal from a perl script?

Which platform?  On Unix you can (for example) do something like this

system q/xterm -e perl -le 'print "line $_" for 1..20; <>'/;

which would print 20 ines in a new xterm, and wait for you to press enter to close the terminal again.  The -e option specifies the command to run in the xterm (some perl, here).  Virtually any other terminal has similar facilities.

Is that what you are trying to do?

    I am running this script on Ubuntu

    The script I am writing pulls a few command line programs together. I want to be able to have one of the programs run in a new terminal while my main program continues to run in the first terminal.

      It can be done, but it's tricky. Here's a script that I wrote to test Module::Install and ExtUtils::MakeMaker.
      #!/usr/bin/perl -l use strict; use warnings; $|=1; open STDOUT, '>-'; system("xterm -e cpan -ft Module::Install &"); close STDOUT; use CPAN; CPAN::Shell->test("ExtUtils::MakeMaker");

      Update: The script requires a lot of RAM, so it may or may not work for you. Try some other commands until it works.

      Update: This will probably work better for you.
      #!/usr/bin/perl -l use strict; use warnings; $| =1; open STDOUT, '>-'; system("du /usr/lib/perl5 &"); close STDOUT; open STDOUT, '>-'; system("xterm -e du /usr/lib/perl5 &"); close STDOUT;

        That did not work.

        I got an error saying: sh: xterm: command not found
