Hi.
Assuming you have entered the following with an editor of your choice:
Code:
#!/usr/bin/perl
# @(#) p1 Demonstrate perl/tk.
# Learning Perl/Tk, O'Reilly, Walsh, 1999, page 11.
use Tk;
my $mw = MainWindow->new;
$mw->title("Hello, world.");
$mw->Button( -text => "Done", -command => sub {exit} )->pack;
MainLoop;
You then may do:
and a small window will be created on your console, assuming all other prerequisites are handled: X is up,
perl is at /usr/bin/perl, etc. This allows you to use this file just like a standard command. I prefer this method. I rarely code in perl/tk, but I have standardized comments for processing with command
what -- that's what the
@(#) comment is about -- you don't need that to run
perl codes. The
chmod need only be done once. After that, edit to your heart's content, and re-run with
./p1
See also the reference below ... cheers, drl
