  1. NAME
  2. scp - secure copy (remote file copy program)
  3. SYNOPSIS
  4. scp -words [-1246BCpqrv ] [-c cipher ] [-F ssh_config ] [-i identity_file ] [-l limit ] [-o ssh_option ] [-P port ] [-S program ] [[user @ ] host1 : file1 ] [... ] [[user @ ] host2 : file2 ]
  5. DESCRIPTION
  6. scp 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), scp will ask for passwords or passphrases if they are needed for authentication.
  8. 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.
  10. The options are as follows:
  12. -1
  13. Forces scp to use protocol 1.
  14. -2
  15. Forces scp to use protocol 2.
  16. -4
  17. Forces scp to use IPv4 addresses only.
  18. -6
  19. Forces scp to use IPv6 addresses only.
  20. -B
  21. Selects batch mode (prevents asking for passwords or passphrases).
  22. -C
  23. Compression enable. Passes the -C flag to ssh(1) to enable compression.
  24. -c cipher
  25. Selects the cipher to use for encrypting the data transfer. This option is directly passed to ssh(1).
  26. -F ssh_config
  27. Specifies an alternative per-user configuration file for ssh This option is directly passed to ssh(1).
  28. -i identity_file
  29. Selects the file from which the identity (private key) for RSA authentication is read. This option is directly passed to ssh(1).
  30. -l limit
  31. Limits the used bandwidth, specified in Kbit/s.
  32. -o ssh_option
  33. Can be used to pass options to ssh in the format used in ssh_config5. This is useful for specifying options for which there is no separate scp command-line flag. For full details of the options listed below, and their possible values, see ssh_config5.
  35. AddressFamily
  36. BatchMode
  37. BindAddress
  38. ChallengeResponseAuthentication
  39. CheckHostIP

  75. TCPKeepAlive
  76. UsePrivilegedPort
  77. User
  78. UserKnownHostsFile
  79. VerifyHostKeyDNS
  81. -P port
  82. Specifies the port to connect to on the remote host. Note that this option is written with a capital `P' because -p is already reserved for preserving the times and modes of the file in rcp(1).
  83. -p
  84. Preserves modification times, access times, and modes from the original file.
  85. -q
  86. Disables the progress meter.
  87. -r
  88. Recursively copy entire directories.
  89. -S program
  90. Name of program to use for the encrypted connection. The program must understand ssh(1) options.
  91. -v
  92. Verbose mode. Causes scp and ssh(1) to print debugging messages about their progress. This is helpful in debugging connection, authentication, and configuration problems.
  95. DIAGNOSTICS
  96. scp exits with 0 on success or >0 if an error occurred.
