Remote file copy
rcp [-p] source_file target_file rcp [-p] [-r] source_file... target_dir
The rcp utility copies files between machines. Each file or directory argument is either of the following:
If the specified path isn't a full pathname, it's interpreted relative to the login directory of the specified user ruser on rhost, or of your current username if no other remote username (rname) is specified. A path on a remote host may be quoted (using \, ", or ') so that the metacharacters are interpreted remotely.
The rcp utility doesn't prompt for passwords; it performs remote execution via rsh, and requires the same authorization.
The rcp utility handles third-party copies, where neither source nor target files are on the current machine.
|This utility needs to have the setuid (“set user ID”) bit set in its permissions. If you use mkefs, mketfs, or mkifs on a Windows host to include this utility in an image, use the perms attribute to specify its permissions explicitly, and the uid and gid attributes to set the ownership correctly.|
The rcp utility requires the libsocket.so shared library.
The rcp utility doesn't always detect that the target of a copy is a file in cases where only a directory should be legal. It's also confused by any output generated by commands in a .login or .profile file on the remote host.
