hi, I've got two text files containing email addresses one at a row. The number of rows in one file is different from the number of the other file. email addresses in one file is already there in the other file (there are some more also). What I want to do is extract the list which is not in the other file. elaboration File A has 100 email addresses and file B has 15 email addresses. 15 email addresses in file B are already there in file A. I want to extract the 85 mails (excluding the 15 from file B) from file A. Any idea on how to accomplish this? -- W.H.Kalpa Pathum ............................................... http://kalpapathum.blogspot.com http://thiraya.wordpress.com http://www.twitter.com/callkalpa ............................................... -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
