NAME
       rdiffdir - compute and apply signatures and diffs to directories

SYNOPSIS
       rdiffdir [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.

DESCRIPTION
       rdiffdir 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.
