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).
rcp [option]... old-file new-file rcp [option]... files... directory
rcpto attempt to preserve (duplicate) in its copies the modification times and modes of the source files, ignoring the umask. By default, the mode and owner of file are preserved if it already existed; otherwise the mode of the source file modified by the
umaskfunction on the destination host is used.
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 can be 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.
