Hi I need a simple perl script that removes duplicate emails from a text file. each line in the text file is in the following form: domain:email example: starting text file: test1.us:email1@hotmail.com test2.us:email2@hotmail.com test3.us:email3@hotmail.com test4.us:email1@hotmail.com test5.us:email2@hotmail.com test6.us:email3@hotmail.com test7.us:email1@hotmail.com test8.us:email2@hotmail.com test9.us:email3@hotmail.com output should be: test1.us:email1@hotmail.com test2.us:email2@hotmail.com test3.us:email3@hotmail.com --> all the lines that have a duplicate email are removed.
