Another method:

$ awk -F " : " '{print $4}' filea.txt | sed '/^$/d'
cn=user1,dc=org,dc=uk
cn=user2,dc=org,dc=uk
cn=user3,dc=org,dc=uk
cn=user4,dc=org,dc=uk
cn=user5,dc=org,dc=uk

NAME
Log::Message::Config - Configuration options for Log::Message SYNOPSIS
# This module is implicitly used by Log::Message to create a config # which it uses to log messages. # For the options you can pass, see the C<Log::Message new()> method. # Below is a sample of a config file you could use # comments are denoted by a single '#' # use a shared stack, or have a private instance? # if none provided, set to '0', private = 1 # do not be verbose verbose = 0 # default tag to set on new items # if none provided, set to 'NONE' tag = SOME TAG # default level to handle items # if none provided, set to 'log' level = carp # extra files to include # if none provided, no files are auto included include = mylib.pl include = ../my/other/lib.pl # automatically delete items # when you retrieve them from the stack? # if none provided, set to '0' remove = 1 # retrieve errors in chronological order, or not? # if none provided, set to '1' chrono = 0 DESCRIPTION
Log::Message::Config provides a standardized config object for Log::Message objects. It can either read options as perl arguments, or as a config file. See the Log::Message manpage for more information about what arguments are valid, and see the Synopsis for an example config file you can use SEE ALSO
