rdiffdir - compute and apply signatures and diffs to directories SYNOPSIS
rdiffdir [options] sig[nature] basis_dir signature_file rdiffdir [options] delta signature_file new_dir delta_file rdiffdir [options] patch basis_dir delta_file rdiffdir [options] tar basis_dir tar_file If signature_file or delta_file are "-", the data will be read from stdin or written to stdout as appropriate. DESCRIPTION
rdiffdir is supposed to be like rdiff, but can operate on directories. See rdiff(1) for more information. The syntax is similar. OPTIONS
--write-sig-to sigfile This option is only used in delta and tar modes. When specified, rdiffdir will write a signature of the directory it is processing to sigfile. The end result will be a delta and a new signature calculated over the same data. -z, --gzip-compress Enable gzip compression and decompression of signature and delta files. SELECTION OPTIONS
In signature and delta modes, rdiffdir accepts duplicity-like selection options including --exclude, --exclude-filelist-stdin, etc. See the duplicity(1) manual page for more information. BUGS
Hard links are currently unsupported (they will be treated as non-linked regular files). Bad signatures will be treated as empty instead of logging appropriate error message. AUTHOR
