in reply to system command with arguments Error

Try this for debugging:
my $cmd = "perl $manuf $series $model $url $kb_color_style_nam +e $kb_color_image_url $kb_color_image_id"; print "cmd is $cmd\n"; system($cmd) == 0 or die "cant run!!";
When it doesn't work, try running the command printed to the screen, and debug that statement.

    this outputs cant run!!

      It should also output what the command was, and you should be able to look at that command and see what's wrong with it. We can't perform the debugging steps for you.


      It should output something more.

      Anyway, a better snippet for debugging:

      use Cwd; my $cmd = "perl $manuf $series $model $url $kb_color_style_nam +e $kb_color_image_url $kb_color_image_id"; print "cmd is $cmd\n"; printf "running at %s\n", getcwd; system($cmd) == 0 or die "cant run!!";

      What does that output?

        Please do output $? and $^E in your error message when system fails.

        system($cmd) == 0 or die "system $cmd failed: $? / $^E"
