rdiff(1)               DragonFly 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.

       The original rsync algorithm was discovered by Andrew Tridgell.

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