       rcp - remote file copy

       rcp [-p]	[-x] [-k realm ] [-D port] [-N]	[-PN | -PO] file1 file2

       rcp  [-p]  [-x] [-k realm] [-r] [-D port] [-N] [-PN | -PO] file ... di-

       Rcp copies files	between	machines.  Each	file or	directory argument  is
       either  a  remote file name of the form ``rhost:path'', or a local file
       name (containing	no `:' characters, or a	`/' before any `:'s).

       By default, the mode and	owner of file2 are preserved if	it already ex-
       isted;  otherwise  the mode of the source file modified by the umask(2)
       on the destination host is used.

       If path is not a	full path name,	it is interpreted relative to your lo-
       gin  directory  on rhost.  A path on a remote host may be quoted	(using
       \, ", or	') so that the metacharacters are interpreted remotely.

       Rcp does	not prompt for passwords; it uses Kerberos authentication when
       connecting  to  rhost.  Each user may have a private authorization list
       in a file .k5login in his login directory.   Each  line	in  this  file
       should  contain	a  Kerberos  principal	name of	the form principal/in-
       stance@realm.  If there is a ~/.k5login file, then access is granted to
       the  account if and only	if the originater user is authenticated	to one
       of the principals named in the ~/.k5login file.	Otherwise, the	origi-
       nating  user  will  be granted access to	the account if and only	if the
       authenticated principal name of the user	can be mapped to the local ac-
       count  name  using  the aname ->	lname mapping rules (see krb5_anadd(8)
       for more	details).

       -p     attempt to preserve (duplicate) the modification times and modes
	      of the source files in the copies, ignoring the umask.

       -x     encrypt all information transferring between hosts.

       -k realm
	      obtain  tickets  for the remote host in realm instead of the re-
	      mote host's realm	as determined by krb_realmofhost(3).

       -r     if any of	the source files are directories,  copy	 each  subtree
	      rooted  at that name; in this case the destination must be a di-


       -PO    Explicitly request new or	old version of the  Kerberos  ``rcmd''
	      protocol.	  The new protocol avoids many security	problems found
	      in the old one, but is not  interoperable	 with  older  servers.
	      (An  "input/output  error"  and  a closed	connection is the most
	      likely result of attempting this combination.)  If  neither  op-
	      tion  is	specified,  some  simple  heuristics are used to guess
	      which to try.

       -D port
	      connect to port port on the remote machine.

       -N     use a network connection,	even when copying files	on  the	 local
	      machine (used for	testing	purposes).

       Rcp  handles  third party copies, where neither source nor target files
       are  on	the  current  machine.	 Hostnames  may	 also  take  the  form
       ``rname@rhost''	to  use	rname rather than the current user name	on the
       remote host.

       ~/.k5login  (on remote host) - file containing Kerberos principals that
		   are allowed access.

       cp(1),  ftp(1), rsh(1), rlogin(1), kerberos(3), krb_getrealm(3),	rcp(1)
       [UCB version]

       Rcp doesn't detect all cases where the target of	a copy might be	a file
       in cases	where only a directory should be legal.

       Rcp  is confused	by any output generated	by commands in a .login, .pro-
       file, or	.cshrc file on the remote host.

       Kerberos	is only	used for the first connection of a  third-party	 copy;
       the second connection uses the standard Berkeley	rcp protocol.
