zelta-match(8) System Manager's Manual zelta-match(8) NAME zelta match - Describes the relationship between a dataset tree and its replica. SYNOPSIS zelta match [-Hp] [-d depth] [-o field[,...]] source-endpoint tar- get-endpoint DESCRIPTION zelta match recursively displays a dataset and its children, similar to the zfs list -r command, except it compares common dataset between the source dataset tree and its target replica. Instead of ZFS Properties, zelta match displays fields describing differences and similarities be- tween the two dataset trees. This is especially useful for assisting with replication operations and confirming backups. -d depth, -depth depth Limit recursion to dataset depth, e.g., -d1 will report on the topmost dataset only. -H Used for scripting mode. Do not print headers and separate fields by a single tab instead of arbitrary white space. -p Display numbers in exact, machine-readable values, instead of units such as B, K, M, or G. -n, -dryrun Show the zfs list commands instead of executing them. -o field[...] A comma-separated list of properties to display. See the Field Options or zelta match -? for details. -q Decrease verbosity. -v Increase verbosity. -W, -no-written Don't estimate sizes by retrieving the "written" property; this significantly speeds up operation, but may incorrectly report replicability, .e.g., if the target has been modified.
