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.
