    sub runscript { system(""); # or if it takes some time to run the script system(" &"); # runs in the background } ... -command => [\&runscript]

    Another option, used more often, is to run the script thru IPC and use Tk's fileevent to watch it.
    #!/usr/bin/perl use warnings; use strict; use IPC::Open3; use Tk; $|=1; my $pid=open3(\*IN,\*OUT,0,'/bin/bash'); my $mw=new MainWindow; $mw->geometry("600x400"); my $t=$mw->Scrolled('Text',-width => 80, -height => 80, )->pack; &refresh; $mw->fileevent(\*OUT,'readable',\&write_t); #keep filling the text widget my $id = Tk::After->new($mw,2000,'repeat',\&refresh); MainLoop; sub refresh{ print IN "top b n 1"; print IN "\n"; #absolutely needed and on separate line } sub write_t { my $str= <OUT>; $t->insert("1.0",$str); # $t->see("0.0"); } __END__
