RDIFFDIR(1) User Manuals RDIFFDIR(1)NAMErdiffdir - compute and apply signatures and diffs to directories
SYNOPSISrdiffdir [options] sig[nature] basis_dir signature_file
rdiffdir [options] delta full_sigtar {incr_sigtar} new_dir delta_file
rdiffdir [options] patch basis_dir delta_file
rdiffdir [options] tar basis_dir tar_file
If signature_file or delta_file are "-", the data will be read from
stdin or written to stdout as appropriate.
DESCRIPTIONrdiffdir is supposed to be like rdiff, but can operate on directories.
See rdiff(1) for more information. The syntax is similar.
Regarding the delta command, the full_sigtar operand is a signa‐
ture_file written by an earlier signature or tar command (the latter
using the --write-sig-to option). The optional incr_sigtar operands are
signature files written by earlier delta commands using the --write-
sig-to option. This way the Nth invocation of the delta command can
parse (and extend) the signature chain that has been founded by the
first signature or tar command with a full signature, and then extended
by the subsequent N-1 delta invocations with incremental signatures. It
is the responsibility of the user to specify the sigtar operands in
logical increment order.
OPTIONS--write-sig-to sigfile
This option is only used in delta and tar modes. When speci‐
fied, rdiffdir will write a signature of the directory it is
processing to sigfile. The end result will be a delta and a new
signature calculated over the same data.
-z, --gzip-compress
Enable gzip compression and decompression of signature and delta
files.
SELECTION OPTIONS
In signature and delta modes, rdiffdir accepts duplicity-like selection
options including --exclude, --exclude-filelist-stdin, etc. See the
duplicity(1) manual page for more information.
BUGS
Hard links are currently unsupported (they will be treated as non-
linked regular files).
Bad signatures will be treated as empty instead of logging appropriate
error message.
