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.
