This seems like a reasonable proposal to enhance zfs list. But it would also be good to add as few new options to zfs list as possible. So it probably makes sense to add at most one of these new options. Or perhaps add an optional depth argument to the -r option instead? As you point out, the -c option is user friendly while the -depth (or maybe -d) option is more general. There have been several requests for the -c option. Would anyone prefer the -depth option? In what cases would this be used? -- Rich _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
