rdiff

rdiff(1)						      General Commands Manual							  rdiff(1)

NAME

       rdiff - compute and apply signature-based file differences

SYNOPSYS

       rdiff [options] signature old-file signature-file

       rdiff [options] delta signature-file new-file delta-file

       rdiff [options] patch basis-file delta-file new-file

USAGE

       You  can  use  rdiff  to  update  files, much like rsync does.  However, unlike rsync, rdiff puts you in control.  There are three steps to
       updating a file: signature, delta, and patch.

DESCRIPTION

       In every case where a filename must be specified, - may be used instead to mean either standard input or standard  output  as  appropriate.
       Be aware that if you do this, you'll need to terminate your options with -- or rdiff will think you are passing it an empty option.

RETURN VALUE

       0  for successful completion, 1 for environmental problems (file not found, invalid options, IO error, etc), 2 for a corrupt file and 3 for
       an internal error or unhandled situation in librsync or rdiff.

SEE ALSO

       librsync(3)

AUTHOR

       Martin Pool <mbp@samba.org>

       The original rsync algorithm was discovered by Andrew Tridgell.

       rdiff development has been supported by Linuxcare, Inc and VA Linux Systems.
