remote copy (r-utility) (rcp)
Remote Copy (rcp) belongs to the Berkeley services and specifically to the r commands.
The rcp service is a protocol for copyingfiles between networked clients and servers, provided they support the rpc daemon. Remote Copy consists only of the rcp command and a single command line.
The rcp protocol uses the same mechanisms for authentication as remote shell( rsh). A file copy can only occur if both computer systems use the same user name.
