NAME

rdup-up - update a directory tree with a rdup archive

SYNOPSIS

rdup-up [OPTION]... DIRECTORY

DESCRIPTION

With rdup-up you can update an (possibly) existing directory structure with a rdup
archive.

The rdup archive has to be given to rdup-up's standard input.

Username and uids
rdup outputs both the username and uid, the receiving system (which may be a totally
different system) checks if the username and uid match. If the username and uid don't
match the (numeric) uid is used on the file. The same holds true for the groupname and
gid.

OPTIONS

-n Do a dry-run and do not create anything on disk.

-t Create DIRECTORY (ala mkdir -p) if it does not exist.

-s N Strip N path components from a pathname. If the resulting pathname is empty after
this operation it is skipped. Be careful however with the following structure:

/foo
/foo/bar
/foo/bar/bla.txt
/foo/blork/bla.txt

With rdup-up -s2 this will leave:

<empty>
<empty>
/bla.txt
/bla.txt

And the last 'bla.txt' will overwrite the previous one, this will happen without
warnings.

-r PATH
This option is related to the -s option, but works different. The string PATH is
removed from (the beginning of) each pathname. With -r /home/backup the pathname
/home/backup/bin/mycmd becomes /bin/mycmd. The same could be done with -s 2, but
then you need to count the slashes. Note -s is always performed before -r.

-v Be more verbose and echo the processed files to standard output.

-vv Be even more verbose and echo processed file and the uid and gid information to
standard output.

-T Show a table of contents of the rdup stream received (ala tar -tf -). With -T the
directory argument is optional. -T unsets any verbose (-v) options.

-h A short help message.

-V Show the version.

EXIT CODE

rdup-up return a zero exit code on success, otherwise 1 is returned.
