    Message : Simplify and unify wording for the -I sourceaddr option in various places. This is somewhat related to the "-b bind_addr" option some programs have, which should get some cleanup also... input florian claudio jmc

.Sh NAME
.Nm openrsync
.Nd synchronise local and remote files
.Sh SYNOPSIS
.Nm openrsync
.Op Fl aDglnoprtvx
.Op Fl e Ar program
.Op Fl -address Ns = Ns Ar sourceaddr
.Op Fl -del
.Op Fl -numeric-ids
.Op Fl -port Ns = Ns Ar service
.Op Fl -rsync-path Ns = Ns Ar program
.Op Fl -version
.Ar source ...
.Ar directory
.Sh DESCRIPTION
The
.Nm
utility synchronises files in the destination
.Ar directory
with one or more
.Ar source
files.
Either the
.Ar source
or the destination
.Ar directory
may be remote,
but not both.
The arguments are as follows:
.Bl -tag -width Ds
.It Fl a , -archive
Shorthand for
.Fl Dgloprt .
.It Fl -address Ns = Ns Ar sourceaddr
When connecting to an rsync daemon, use
.Ar sourceaddr
as the source address for connections, which is useful on machines with
multiple interfaces.
.It Fl D
Also transfer device and special files.
Shorthand for
.Fl -devices -specials .
.It Fl -del , -delete
Delete files in
.Ar directory
not found in
.Ar source
directories.
Only applicable with
.Fl r .
.It Fl -devices
Also transfer device files.
.It Fl e Ar program , Fl -rsh Ns = Ns Ar program
Specify alternative communication program, defaults to
.Xr ssh 1 .
.It Fl g , -group
Set the group name to match the source.
For example, group
.Qq kristaps
with ID 1000 on a remote server is matched to group
.Qq kristaps
on the local machine with ID 2000.
If
.Fl -numeric-ids
is also given or if the remote group name is unknown on the local machine,
set the numeric group ID to match the source instead.
.It Fl l , -links
Also transfer symbolic links.
The link is transferred as a standalone file: if the destination does
not exist, it will be broken.
.It Fl n , -dry-run
Do not actually modify the destination.
Mainly useful in combination with
.Fl v .
.It Fl -numeric-ids
Ignore user and group names, use numeric user and group IDs only.
Has no effect unless
.Fl g
or
.Fl o
is also given.
.It Fl o , -owner
Set the user name to match the source, with similar matching logic as for
.Fl g .
If
.Fl -numeric-ids
is also given or if the remote user name is unknown on the local machine,
set the numeric user ID to match the source instead.
Only works if run as root.
.It Fl p , -perms
Set destination file or directory permissions to match the source when
it is updated.
.It Fl -port Ns = Ns Ar service
Specify an alternative TCP port number.
The
.Ar service
can be given as a decimal integer or as a name to be looked up in the
.Xr services 5
database.
The default is
.Dq rsync .
.It Fl r , -recursive
If
.Ar source
designates a directory, synchronise the directory and the entire subtree
connected at that point.
If
.Ar source
ends with a slash, only the subtree is synchronised, not the
.Ar source
directory itself.
If
.Ar source
is a file, this has no effect.
.It Fl -rsync-path Ns = Ns Ar program
Run
.Ar program
on the remote host instead of the default
.Pa rsync .
.It Fl -specials
Also transfer fifo and unix domain socket files.
.It Fl t , -times
Set destination file and directory modification time to match the source
when it is updated or created.
.It Fl v , -verbose
Increase verbosity.
Specify once for files being transferred, twice for specific status,
thrice for per-file transfer information, and four times for per-file
breakdowns.
.It Fl x
Do not cross filesystem boundaries.
If this option is repeated, all mount point directories from the copy are
omitted.
Otherwise, it includes an empty directory at each mount point it encounters.
.It Fl -version
Print version and exit.
.El
.Pp
A remote
.Ar source
or
.Ar directory
has the syntax
.Ar host : Ns Ar path
for connecting via
.Xr ssh 1 ,
or
.Cm rsync Ns :// Ns Ar host Ns / Ns Ar path
or
.Ar host Ns :: Ns Ar path
for connecting to a remote daemon.
Subsequent to the first remote
.Ar source ,
the host may be dropped to become just
.Pf : Ar path
or
.Pf :: Ar path .
.Pp
For connecting to a remote daemon with
.Cm rsync Ns :// Ns Ar host
or
.Ar host Ns :: Ns Ar path ,
the first path component is interpreted as a
.Qq module :
.Ar host Ns :: Ns Ar module Ns / Ns Ar path .
This only applies to the first
.Ar source
invocation; subsequent to that, the module should not be specified.
.Pp
By default, new destination files and directories are given the current
time and the source file permissions.
Updated files retain their existing permissions.
It is an error if updated files have their file types change (e.g.,
updating a directory with a file).
.Pp
At this time,
.Ar source
may only consist of regular files, directories
.Pq only with Fl r ,
or symbolic links
.Pq only with Fl l .
The destination
.Ar directory
must be a directory and is created if not found.
.\" .Sh ENVIRONMENT
.\" .Sh FILES
.Sh EXIT STATUS
The
.Nm
utility exits 0 on success, 1 if an error occurs, or 2 if the remote
protocol version is older than the local protocol version.
.Sh EXAMPLES
All examples use
.Fl t
so that destination files inherit the source time.
If not changed, subsequent invocations of
.Nm
will then consider the file up to date and not transfer block hashes.
.Pp
To update the out-of-date remote files
.Pa host:dest/bar
and
.Pa host:dest/baz
with the local
.Pa ../src/bar
and
.Pa ../src/baz :
.Pp
.Dl % rsync -t ../src/bar ../src/baz host:dest
.Pp
To update the out-of-date local files
.Pa bar
and
.Pa baz
with the remote files
.Pa host:src/bar
and
.Pa host:src/baz :
.Pp
.Dl % rsync -t host:src/bar :src/baz \&.
.Pp
To update the out-of-date local files
.Pa ../dest/bar
and
.Pa ../dest/baz
with
.Pa bar
and
.Pa baz :
.Pp
.Dl % rsync -t bar baz ../dest
