If the -r option is specified and any of the source files are directories, rcp copies each subtree rooted at that name; in this case the destination must be a directory.
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. The -p option causes rcp to attempt to preserve (duplicate) in its copies the modification times and modes of the source files, ignoring the umask.
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 ยด) so that the metacharacters are interpreted remotely.
Rcp does not prompt for passwords; your current local user name must exist on rhost and allow remote command execution via rsh(1C).
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.
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 version of rcp.
