SYNOPSIS

       rdiffdir [options] sig[nature] basis_dir signature_file

       rdiffdir [options] delta signature_file 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.

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.
