NAME
       rcp - remote file copy

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

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

DESCRIPTION
       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 existed; 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  login  directory  on
       rhost.	A  path on a remote host may be quoted (using \, ", or ') so that the metacharac-
       ters 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/instance@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 originating 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  account  name  using  the  aname -> lname mapping rules (see krb5_anadd(8) for more
       details).

OPTIONS
       -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 remote 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 directory.

       -PN

       -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 interopera-
	      ble  with  older	servers.  (An "input/output error" and a closed connection is the
	      most likely result of attempting this combination.)  If neither  option  is  speci-
	      fied, 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.

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

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

BUGS
       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, .profile, or .cshrc  file
       on the remote host.

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