 SCP(1)                  System General Commands Manual                  SCP(1)
 


NAME
      scp - secure copy  remote(file copy program)
 


SYNOPSIS
      scp [-pqrvC46] [-S program] [-P port] [-c cipher] [-i identity_file]
          [-o option] [[user@]host1:]file1 [...] [[user@]host2:]file2
 


DESCRIPTION
      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.
 
      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:
 
      -c cipher
              Selects the cipher to use for encrypting the data transfer.  This
              option is directly passed to ssh(1).
 
      -i identity_file
              Selects the file from which the identity (private key) for RSA
              authentication is read.  This option is directly passed to
              ssh(1).
 
      -p      Preserves modification times, access times, and modes from the
              original file.
 
      -r      Recursively copy entire directories.
 
      -v      Verbose mode.  Causes scp and ssh(1) to print debugging messages
              about their progress.  This is helpful in debugging connection,
              authentication, and configuration problems.
 
      -B      Selects batch mode (prevents asking for passwords or
              passphrases).
 
      -q      Disables the progress meter.
 
      -C      Compression enable.  Passes the -C flag to ssh(1) to enable com­
              pression.
 
      -P port
              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).
 
      -S program
              Name of program to use for the encrypted connection.  The program
              must understand ssh(1) options.
 
      -o option
              The given option is directly passed to ssh(1).
 
      -4      Forces scp to use IPv4 addresses only.
 
      -6      Forces scp to use IPv6 addresses only.
