Remove duplicates

I have a file with the following format:

fields seperated by "|"

title1|something class|long...content1|keys
title2|somhing class|log...content1|kes
title1|sothing class|lon...content1|kes
title3|shing cls|log...content1|ks

I want to remove all duplicates with the same "title field"(the 1st column) regardless anything following in that line.

thanks a lot.

Device::Modem::Log::File(3pm)				User Contributed Perl Documentation			     Device::Modem::Log::File(3pm)

NAME
Device::Modem::Log::File - Text files logging plugin for Device::Modem class SYNOPSIS
use Device::Modem; my $box = Device::Modem->new( log => 'file', ... ); my $box = Device::Modem->new( log => 'file,name=/var/log/mymodem.log', ... ); ... DESCRIPTION
This is meant for an example log class to be hooked to "Device::Modem" to provide one's favourite logging mechanism. You just have to implement your own "new()", "write()" and "close()" methods. Default text file is "/var/log/modem.log". On Windows platforms, this goes into "%WINBOOTDIR%/temp/modem.log". By default, if the folder of the log file does not exist, it is created. This class is loaded automatically by "Device::Modem" class when an object is instantiated, and it is the default logging mechanism for "Device::Modem" class. Normally, you should not need to use this class directly, because there are many other zillions of modules that do logging better than this. Also, it should be pondered whether to replace "Device::Modem::Log::File" and mates with those better classes in a somewhat distant future. REQUIRES Device::Modem EXPORTS None AUTHOR
