  rcp - Copies files between a local and a remote host or between two remote


  rcp [-pr] source destination

  The remote copy command (rcp) is used to copy one or more files between the
  local host and a remote host, between two remote hosts, or between files at
  the same remote host.


  -p  Preserves the modification times and modes of the source files in the
      copies sent to the destination.  Without this flag, the umask command
      at the destination modifies the mode of the destination file, and the
      modification time of the destination file is set to the time the file
      is received.

  -r  Copies recursively, for directories only, each file and subdirectory in
      the source directory into the destination directory.


  By default, the mode and owner of an existing destination file are
  preserved.  Normally, if a destination file does not exist, the mode of the
  destination file is equal to the mode of the source file as modified by the
  umask command at the destination host.  If the -p flag is set, the modifi-
  cation time and mode of source files are preserved at the destination host.
  If a remote hostname is not specified for either the source or the destina-
  tion, rcp is equivalent to the cp command.

  When copying files to or from a remote host, any remote filename or direc-
  tory name must be prefixed by the name of the remote host and a : (colon).
  Local filenames and directory names do not need to have a host specified.
  However, since rcp assumes that a colon terminates a hostname, local
  filenames or directory names must have a \ (backslash) inserted before any
  colons embedded in the name.

  The username entered for the remote host determines the file access
  privileges rcp uses at that host.  Additionally, the username given to a
  destination host determines the ownership and access modes of the resulting
  destination file or files. If a hostname is not prefixed by user@, the
  local username is used at the remote host.  If a username is entered, that
  name is used.	 In either case, the remote host allows access if one of the
  following conditions is satisfied:

    +  The local host is included in the remote host's /etc/hosts.equiv file
       and the remote user is not the superuser.

    +  The local host and username is included in a $HOME/.rhosts file in the
       home directory of the remote user account.  For security reasons, any
       $HOME/.rhosts file must be owned by either the remote user or the root
       user and should allow Write access only by the owner.

  In addition to the preceding conditions, rcp also allows access to the
  remote host if the remote user account does not have a password defined.
  However, for security reasons, use of a password on all user accounts is

  If the path for a file or directory on a remote host is not specified or is
  not fully qualified, the path is interpreted as beginning at the home
  directory for the remote user account.  Additionally, any metacharacters
  that must be interpreted at a remote host must be quoted using \
  (backslash), "" (double quotes), or '' (single quotes).


   1.  To copy a file named localfile from the local host to a remote host
       named host2, enter:
	    rcp localfile host2:/u/eng/fred

   2.  To copy a remote file named newplan from one remote host, host1, to
       another remote host, host2, enter:
	    rcp host1:/u/eng/fred/newplan host2:/u/eng/mary

   3.  To send a directory subtree report from the local host to the home
       directory of a user named fred at a remote host named host2, and
       preserve all modes and modification times, enter:
	    rcp -p -r report fred@host2:report

       The remote file /u/fred/.rhosts includes an entry specifying the local
       host and username.


  The rcp command is confused by output generated by commands in a .cshrc
  file on the remote host.  In particular, the messages, where are you? and
  stty: Can't assign requested address can result if output is generated by
  the startup file.


	     Specifies remote hosts from which users can execute commands on
	     the local host (provided these users have an account on the
	     local host).

	     Specifies remote users who can use a local user account.


  Commands:  rsh(1), rlogin(1), rshd(8).

  Files:  rhosts(4).
