I'd probably quote it like: yum --exclude='dovecot*' update as a matter of habit to emphasize that I don't want any substitutions, but in this case double quotes or \ escaping would all be the same.

The basics haven't changed in decades and they can save you a lot of work. -- Les Mikesell lesmikesell@xxxxxxxxx -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
