Re: Filering a file

[Sara]

Here is a small piece of code if it could be helpful.

## START #

#!f:/perl/bin/perl.exe
# set the above to your perl path.

use strict;
use warnings;
use CGI qw(:standard);
use CGI::Carp 'fatalsToBrowser';

my $q = new CGI;

open (DUPF,"dupes.txt"); # name of the file containig dupes to be removed.
open (OUTF,">>dupes_removed.txt"); #new file with dupes removed.
my %saw;
print OUTF grep(!$saw{$_}++,);
close OUTF;
close DUPF;

print $q->header();
print "Duplicate Enteries Removed";

exit;

# End of Code 

Thanks,

Sara.

Hello David,

I'm able to open the file, read the contents and output the results of my
initial filtering to a new file.

The problem is that my new file has duplicate entries, and cleaning up
duplicates is where I'm stuck.

Kind regards

Dayo

What have you tried?  Where are you stuck? (Opening the file? Reading
the contents? The actual filtering?). Nothing in your question is CGI
related, have you got this working as a command line script but are
having trouble converting it to work under CGI? What code have you got
so far?

You are a man of honour Sean.

I maintain an account with Safari Online books (http://safari.informit.com)
which I find to be an invaluable resource for access to these books.

Kind regards

To Chris and others on the list, I apologize.  More importantly, I should
apologize to Tom Christiansen and Nathan Torkington, the authors of the book
in question.  I was much too quick to post the link from google without
reading the copyright (quoted below) available as a link from the homepage
for the site.  This was unacceptable of me to do, particularly on a list
that claims to be giving advice to beginners.  Again, my sincerest
apologies.

These are pirated copies of the books in question, hosted on a Ukranian

There are legit ways to get access to these books, including O'Reilly's

I'd have expected someone with a .gov address to be more cognizant of

Filering a file

[Adedayo Adeyeye]

I have a file that contains a listing of names like:

 

John

Paul

Kate
Paul

Charles

Kate

 

How do I write a script to parse through this file and just
return the unique names. Ie I want the repetitions ignored.

 

Kind regards
