And that's what it does. It matches the empty string at the beginning of the line - and it would also (greedily) match digits at the beginning of the line, but there are none. Try echo '123This is a test 12335 and 669384 535xy4' | sed 's/[0-9]*//' > And somehow it does work when you use /g so it is > matching more. No, it's not matching *more*, it's matching *again* (that's exactly what the g flag tells it to). -- Regards mks -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: http://lists.fedoraproject.org/admin/lists/users@lists.fedoraproject.org Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
