DESCRIPTION
The zck_delta_size
utility examines two
zchunk compressed files and determines how similar they are: how many chunks
are the same between the files, so that tools like e.g.
rsync(1) or
zckdl(1) could only transfer the
small parts that differ instead of the full files. This is especially useful
for structured files that have been compressed using the
zck(1) tool's
-s
(--split
) option.
The zck_delta_size
utility accepts the
following optional arguments:
EXIT STATUS
The zck_delta_size
utility exits 0
on success, and >0 if an error occurs.
EXAMPLES
Examine two zchunk files:
zck_delta_size doc1.txt.zck
doc2.txt.zck
