Shell command output unique IDs... comm command

[acctman]

i'm using the line command comm but i'm getting zero results.
comm -23 newid.txt master.txt > new.txt

I'm trying to pull all the unique id's from newid.txt is there another method I can use? both files have been sorted already.

-23 disregards columns 2 and 3, is that what you're looking for? without seeing a sample of each file it's hard to guess.

Have you tried something like this:

diff newid.txt master.txt > new.txt

did you get this figured out?

If you just want unique names ...

Here is a Perlish way to do it ...

#!/usr/bin/perl

use CGI::Carp qw/fatalsToBrowser/;
use CGI qw/:standard/;
use strict;
use warnings;

print "Content-type: text/html\n\n";



my $raw="file1";
#my $sorted="file2";#open and print file
open RAW,"<", $raw or die "<raw";
my @array=(<RAW>);


               my %seen = ();
               my @unique = grep { ! $seen{ $_ }++ } @array;

foreach my  $unique( @unique ){
chomp;
print "$unique<BR>\n";

}

you could just sort with the -u variable for unique
