copies files between hosts on a network. It uses ssh(1) for data transfer, and uses the same authentication and provides the same security as ssh(1) Unlike rcp(1) will ask for passwords or passphrases if they are needed for authentication.
Any file name may contain a host and user specification to indicate that the file is to be copied to/from that host. Copies between two remote hosts are permitted.
The options are as follows:
  • 1 Forces to use protocol 1.
  • 2 Forces to use protocol 2.
  • 4 Forces to use IPv4 addresses only.
  • 6 Forces to use IPv6 addresses only.
  • B Selects batch mode (prevents asking for passwords or passphrases).
  • C Compression enable. Passes the flag to ssh(1) to enable compression.
  • cipher Selects the cipher to use for encrypting the data transfer. This option is directly passed to ssh(1)
  • ssh_config Specifies an alternative per-user configuration file for This option is directly passed to ssh(1)
  • identity_file Selects the file from which the identity (private key) for RSA authentication is read. This option is directly passed to ssh(1)
  • limit Limits the used bandwidth, specified in Kbit/s.
  • ssh_option Can be used to pass options to in the format used in ssh_config(5) This is useful for specifying options for which there is no separate command-line flag. For full details of the options listed below, and their possible values, see ssh_config(5)

  • port Specifies the port to connect to on the remote host. Note that this option is written with a capital because is already reserved for preserving the times and modes of the file in rcp(1)
  • p Preserves modification times, access times, and modes from the original file.
  • q Disables the progress meter.
  • r Recursively copy entire directories.
  • program Name of to use for the encrypted connection. The program must understand ssh(1) options.
  • v Verbose mode. Causes and ssh(1) to print debugging messages about their progress. This is helpful in debugging connection, authentication, and configuration problems.
