display content in file to listbox

Posted by wei (wei), 10 May 2007
Hi

i had execute a linux command to list all the file in /root and store the output in a file. When i open the file and print the content to a listbox which i had created, the content are not arrange properly.
as in
-rw------- 1 root root 123 Nov 1 12.00 a.txt
-rwxrwxrwx 1 root root 124 Dec 4 17.34 b.txt
             .......
i wish to show it in this format to make it nicer
-rw-------                 1 root root 123 Nov 1  12.00 a.txt
-rwxrwxrwx   1root root 124 Dec 3  17.34 b.txt

is there any method to print it in the second format ?

thanks

Apart from one saying 4th December and the other saying 3rd, what's teh difference?   They look the same to me?   And, by the way, how's this a Perl question and how does it relate to a listbox??

This is my code...sorry coz i just started learning perl...i wanted to show the detail as displayed in the file but when it was shown in the listbox, each string in the line was separated by a specific amount of space...

#!/usr/bin/perl -w

use Tk;

my $main = new MainWindow();
$main->resizable(0,0);

my $list = $main->Listbox(-width=>60, -height=>10);
$list -> grid(-row=>2, -column=>1);
my $yaxis = $main->Scrollbar(-orient=>'v', -command=>[yview=>$list]);
$yaxis -> grid(-row=>2, -column=>2, -stick=>'ns');
my $xaxis = $main->Scrollbar(-orient=>'h', -command=>[xview=>$list]);
$xaxis -> grid(-row=>3, -column=>1, -stick=>'ew');
$list -> configure(-yscrollcommand=>['set',$yaxis],
              -xscrollcommand=>['set',$xaxis]);
my $show = $main->Button(-text=>"show",-command=>\&show);
$show -> grid(-row=>4, -column=>1, -sticky=>'w');

MainLoop;

sub show
{
     $list -> delete('0.1','end');
     my $display = `ls -l /root > to.log`;
     open FILE, "to.log";
     while(<FILE>)
     {
           my $line = $_;
           chomp($line);
           $list -> insert('end',$line);
     }
     close FILE;
}

sub end
{
     exit(0);
}
