rcp - remote file copy

SYNOPSIS
    rcp [ -p ] filename1 filename2
    rcp [ -pr ] filename...directory

DESCRIPTION
    The  rcp  command  copies  files  between  machines.    Each
    filename  or directory argument is either a remote file name
    of the form:

hostname:path

rcp does not prompt for passwords; your current  local  user
name  must exist on hostname and allow remote command execu-
tion by rsh(1).

rcp handles third party copies,  where  neither  source  nor
target files are on the current machine.  Hostnames may also
take the form

username@hostname:filename

NOTES

rcp can become confused by output generated by commands in a
$HOME/.profile on the remote host.

rcp requires that the source host have permission to execute
commands on the remote host when doing third-party copies.
