I have a plain text list of email addresses. Can anyone help me with a one liner (sed?) to strip out the invalid ones? I can see for example that there are telephone numbers in there, and lines with no @ sign which I'd like to get rid of. many thanks -- Gllug mailing list - Gllug at gllug.org.uk http://lists.gllug.org.uk/mailman/listinfo/gllug
