Remove rcmds.
If they are still needed, you can find them in the net/bsdrcmds port. This was proposed June, 20th and approved by various committers [1]. They have been marked as deprecated on CURRENT in r320644 [2] on July, 4th. Both stable/11 and release/11.1 contain the deprecation notice (thanks to allanjude@). Note that ruptime(1)/rwho(1)/rwhod(8) were initially thought to be part of rcmds but this was a mistake and those are therefore NOT removed.

|

.Sh DEPRECATION NOTICE
|
||||
.Nm
|
||||
is deprecated and will be removed from future versions of the
|
||||
.Fx
|
||||
base system.
|
||||
If
|
||||
.Nm
|
||||
is still required, it can be installed from ports or packages
|
||||
(net/bsdrcmds).
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
utility copies files between machines.
|
||||
Each
|
||||
.Ar file
|
||||
or
|
||||
.Ar directory
|
||||
argument is either a remote file name of the
|
||||
form
|
||||
.Dq ruser@rhost:path ,
|
||||
or a local file name (containing no
|
||||
.Ql :\&
|
||||
characters,
|
||||
or a
|
||||
.Ql /
|
||||
before any
|
||||
.Ql :\& Ns
|
||||
s).
|
||||
.Pp
|
||||
The following options are available:
|
||||
.Bl -tag -width indent
|
||||
.It Fl 4
|
||||
Use IPv4 addresses only.
|
||||
.It Fl 6
|
||||
Use IPv6 addresses only.
|
||||
.It Fl p
|
||||
Cause
|
||||
.Nm
|
||||
to attempt to preserve (duplicate) in its copies the modification
|
||||
times and modes of the source files, ignoring the
|
||||
.Xr umask 2 .
|
||||
By default, the mode and owner of
|
||||
.Ar file2
|
||||
are preserved if it already existed; otherwise the mode of the source file
|
||||
modified by the
|
||||
.Xr umask 2
|
||||
on the destination host is used.
|
||||
.It Fl r
|
||||
If any of the source files are directories,
|
||||
.Nm
|
||||
copies each subtree rooted at that name; in this case
|
||||
the destination must be a directory.
|
||||
.El
|
||||
.Pp
|
||||
If
|
||||
.Ar path
|
||||
is not a full path name, it is interpreted relative to
|
||||
the login directory of the specified user
|
||||
.Ar ruser
|
||||
on
|
||||
.Ar rhost ,
|
||||
or your current user name if no other remote user name is specified.
|
||||
A
|
||||
.Ar path
|
||||
on a remote host may be quoted (using
|
||||
.Ql \e ,
|
||||
.Ql \&" ,
|
||||
or
|
||||
.Ql \(aa )
|
||||
so that the metacharacters are interpreted remotely.
|
||||
.Pp
|
||||
The
|
||||
.Nm
|
||||
utility does not prompt for passwords; it performs remote execution
|
||||
via
|
||||
.Xr rsh 1 ,
|
||||
and requires the same authorization.
|
||||
.Pp
|
||||
The
|
||||
.Nm
|
||||
utility handles third party copies, where neither source nor target files
|
||||
are on the current machine.
|
||||
.Sh SEE ALSO
|
||||
.Xr cp 1 ,
|
||||
.Xr ftp 1 ,
|
||||
.Xr rlogin 1 ,
|
||||
.Xr rsh 1 ,
|
||||
.Xr hosts.equiv 5
|
||||
.Sh HISTORY
|
||||
The
|
||||
.Nm
|
||||
command appeared in
|
||||
.Bx 4.2 .
|
||||
The version of
|
||||
.Nm
|
||||
described here
|
||||
has been reimplemented with Kerberos in
|
||||
.Bx 4.3 Reno .
|
||||
.Sh BUGS
|
||||
Does not detect all cases where the target of a copy might
|
||||
be a file in cases where only a directory should be legal.
|
||||
.Pp
|
||||
Is confused by any output generated by commands in a
|
||||
.Pa .login ,
|
||||
.Pa .profile ,
|
||||
or
|
||||
.Pa .cshrc
|
||||
file on the remote host.
|
||||
.Pp
|
||||
The destination user and hostname may have to be specified as
|
||||
.Dq rhost.ruser
|
||||
when the destination machine is running the
|
||||
.Bx 4.2
|
||||
version of
|
||||
.Nm .
