zfs-diff-move

Script to replicate moves reported by zfs diff. Note this is a potentially destructive operation if the --clobber option is provided.

USAGE: zfs-diff-move.sh [--clobber] dir zfs-dir zfsdataset@old-snap [[zfsdataset]@new-snap]

Uses zfs diff to find what files have been moved on the ZFS dataset zfsdataset since the snapshot @old-snap (until @new-snap or the present if not specified). zfs-dir/ should be the mountpoint of zfsdataset or a subdirectory of it. All file moves like zfs-dir/some/path to zfs-dir/another/name will have the equivalent file move applied to the directory structure under dir/: dir/some/path to dir/another/name.

IMPORTANT: Using the --clobber option can lead to data loss if dir/another/name already exists. Otherwise (or if the default --no-clobber is explicitly specified), moves that would overwrite will instead be skipped.

zfs-diff-move-small.sh does the same thing but is written more tersely and handles fewer edge cases in order to squeeze into the text of a blog post.
