|

.Nm rcp

|
|
.Sh DESCRIPTION
|
|
.Nm Rcp
|
|
copies files between machines. Each
|
|
.Ar file
|
|
or
|
|
.Ar directory
|
|
argument is either a remote file name of the
|
|
form ``rname@rhost:path'', or a local file name (containing no `:' characters,
|
|
or a `/' before any `:'s).
|
|
.Pp
|
|
.Bl -tag -width flag
|
|
.It Fl K
|
|
The
|
|
.Fl K
|
|
option turns off all Kerberos authentication.
|
|
.It Fl k
|
|
The
|
|
.Fl k
|
|
option requests
|
|
.Nm rcp
|
|
to obtain tickets
|
|
for the remote host in realm
|
|
.Ar realm
|
|
instead of the remote host's realm as determined by
|
|
.Xr krb_realmofhost 3 .
|
|
.It Fl p
|
|
The
|
|
.Fl p
|
|
option causes
|
|
.Nm rcp
|
|
to attempt to preserve (duplicate) in its copies the modification
|
|
times and modes of the source files, ignoring the
|
|
.Ar umask .
|
|
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 rcp
|
|
copies each subtree rooted at that name; in this case
|
|
the destination must be a directory.
|
|
.It Fl x
|
|
The
|
|
.Fl x
|
|
option turns on
|
|
.Tn DES
|
|
encryption for all data passed by
|
|
.Nm rcp .
|
|
This may impact response time and
|
|
.Tn CPU
|
|
utilization, but provides
|
|
increased security.
|
|
.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 \e, ", or \(aa)
|
|
so that the metacharacters are interpreted remotely.
|
|
.Pp
|
|
.Nm Rcp
|
|
does not prompt for passwords; it performs remote execution
|
|
via
|
|
.Xr rsh 1 ,
|
|
and requires the same authorization.
|
|
.Pp
|
|
.Nm Rcp
|
|
handles third party copies, where neither source nor target files
|
|
are on the current machine.

|
.Sh HISTORY
|
|
The
|
|
.Nm rcp
|
|
command appeared in
|
|
.Bx 4.2 .
|
|
The version of
|
|
.Nm rcp
|
|
described here
|
|
has been reimplemented with Kerberos in
|
|
.Bx 4.3 Reno .
|
|
.Sh BUGS
|
|
Doesn't 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
|
|
``rhost.rname'' when the destination machine is running the
|
|
.Bx 4.2
|
|
version of
|
|
.Nm rcp .
