NAME

6       rdiff - compute and apply signature-based file differences
7

SYNOPSYS

9       rdiff [options] signature old-file signature-file
10
11       rdiff [options] delta signature-file new-file delta-file
12
13       rdiff [options] patch basis-file delta-file new-file
14

USAGE

16       You  can  use  rdiff  to  update files, much like rsync does.  However,
17       unlike rsync, rdiff puts you in control.   There  are  three  steps  to
18       updating a file: signature, delta, and patch.
19

DESCRIPTION

21       In every case where a filename must be specified, - may be used instead
22       to mean either standard input or standard output  as  appropriate.   Be
23       aware  that  if you do this, you'll need to terminate your options with
24       -- or rdiff will think you are passing it an empty option.
25

RETURN VALUE

27       0 for successful completion, 1 for  environmental  problems  (file  not
28       found,  invalid options, IO error, etc), 2 for a corrupt file and 3 for
29       an internal error or unhandled situation in librsync or rdiff.
