NAME
rdiff - compute and apply signature-based file differencesSYNOPSYS
rdiff [options] signature old-file signature-file
rdiff [options] delta signature-file new-file delta-file
rdiff [options] patch old-file delta-file new-fileUSAGE
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. Use
the signature subcommand to generate a small signature-file from the old-file. Use the delta subcommand to generate a small delta-file from the signature-file to the new-file. Use the
patch subcommand to apply the delta-file to the old-file to regenerate the new-file.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
