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 signature_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 specified, 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.
