NAME

     rcp - remote file copy


SYNOPSIS

     rcp [-Kpx] [-k realm] file1 file2
     rcp [-Kprx] [-k realm] file ...  directory


DESCRIPTION

     rcp copies files between machines.  Each file or 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).

     -K    The -K option turns off all Kerberos authentication.

     -k    The -k option requests rcp to obtain tickets for the remote host in
           realm realm instead of the remote host's realm as determined by
           krb_realmofhost(3).

     -p    The -p option causes rcp to attempt to preserve (duplicate) in its
           copies the modification times and modes of the source files, ignor-
           ing the umask.  By default, the mode and owner of file2 are pre-
           served if it already existed; otherwise the mode of the source file
           modified by the umask(2) on the destination host is used.

     -r    If any of the source files are directories, rcp copies each subtree
           rooted at that name; in this case the destination must be a direc-
           tory.

     -x    The -x option turns on DES encryption for all data passed by rcp.
           This may impact response time and CPU utilization, but provides in-
           creased security.

     If path is not a full path name, it is interpreted relative to the login
     directory of the specified user ruser on rhost, or your current user name
     if no other remote user name is specified.  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 performs remote execution via
     rsh(1), and requires the same authorization.

     rcp handles third party copies, where neither source nor target files are
     on the current machine.

HISTORY

     The rcp utility appeared in 4.2BSD.  The version of rcp described here
     has been reimplemented with Kerberos in 4.3BSD-Reno.


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.

     Is confused by any output generated by commands in a .login, .profile, or
     .cshrc file on the remote host.

     The destination user and hostname may have to be specified as
     ``rhost.rname'' when the destination machine is running the 4.2BSD ver-
     sion of rcp.
