rcp - Copies files between a local and a remote host or between two remote hosts
rcp [-pr] source destination
The remote copy command (rcp) is used to copy one
or more files between the local host and a remote host, between two remote
hosts, or between files at the same remote host.
Preserves the modification times and modes of the source files
in the copies sent to the destination. Without this option, the
command at the destination modifies the mode of the destination
file, and the modification time of the destination file is set to the time
the file is received.
Copies recursively, for directories only, each file and subdirectory
in the source directory into the destination directory.
By default, the mode and owner of an existing destination file are preserved. Normally, if a destination file does not exist, the mode of the destination file is equal to the mode of the source file as modified by the umask command at the destination host. If the -p option is set, the modification time and mode of source files are preserved at the destination host. If a remote hostname is not specified for either the source or the destination, rcp is equivalent to the cp command.
When copying files to or from a remote host, any remote filename or directory name must be prefixed by the name of the remote host and a : (colon). Local filenames and directory names do not need to have a host specified. However, since rcp assumes that a colon terminates a hostname, local filenames or directory names must have a \ (backslash) inserted before any colons embedded in the name.
The username entered for the remote host determines the file access privileges rcp uses at that host. Additionally, the username given to a destination host determines the ownership and access modes of the resulting destination file or files. If a hostname is not prefixed by user@, the local username is used at the remote host. If a username is entered, that name is used. In either case, the remote host allows access if one of the following conditions is satisfied: The local host is included in the remote host's /etc/hosts.equiv file and the remote user is not the superuser. The local host and username is included in a $HOME/.rhosts file in the home directory of the remote user account. For security reasons, any $HOME/.rhosts file must be owned by either the remote user or the root user and should have permissions set to 600 (read and write by owner only).
In addition to the preceding conditions, rcp also allows access to the remote host if the remote user account does not have a password defined. However, for security reasons, use of a password on all user accounts is recommended.
If the path for a file or directory on a remote host is not specified
or is not fully qualified, the path is interpreted as beginning at the home
directory for the remote user account. Additionally, any metacharacters that
must be interpreted at a remote host must be quoted using \ (backslash),
" " (double quotes), or ' ' (single quotes).

commands in a
file on the remote host. In particular,

To copy a file named localfile from the local host to a remote host named host2, enter: rcp localfile host2:/u/eng/fred To copy a remote file named newplan from one remote host, host1, to another remote host, host2, enter: rcp host1:/u/eng/fred/newplan host2:/u/eng/mary To send a directory subtree report from the local host to the home directory of a user named fred at a remote host named host2, and preserve all modes and modification times, enter: rcp -p -r report fred@host2:report
Specifies remote hosts from which users can execute commands
on the local host (provided these users have an account on the local host).
Specifies remote users who can use a local user account.
