SCP(1)			  BSD General Commands Manual			SCP(1)

NAME
     scp - secure copy (remote file copy program)

SYNOPSIS
     scp [-1246BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file]
	 [-l limit] [-o ssh_option] [-P port] [-S program]
	 [[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.

     When copying a source file to a target file which already exists, scp
     will replace the contents of the target file (keeping the inode).

     If the target file does not yet exist, an empty file with the target file
     name is created, then filled with the source file contents.  No attempt
     is made at "near-atomic" transfer using temporary files.

     The options are as follows:

     -1	     Forces scp to use protocol 1.

     -2	     Forces scp to use protocol 2.

     -4	     Forces scp to use IPv4 addresses only.

     -6	     Forces scp to use IPv6 addresses only.

     -B	     Selects batch mode (prevents asking for passwords or
	     passphrases).

     -C	     Compression enable.  Passes the -C flag to ssh(1) to enable com-
	     pression.

     -c cipher
	     Selects the cipher to use for encrypting the data transfer.  This
	     option is directly passed to ssh(1).

     -F ssh_config
	     Specifies an alternative per-user configuration file for ssh.
	     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).

     -l limit
	     Limits the used bandwidth, specified in Kbit/s.

     -o ssh_option
	     Can be used to pass options to ssh in the format used in
	     ssh_config(5).  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_config(5).

     -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).

     -p	     Preserves modification times, access times, and modes from the
	     original file.

     -q	     Disables the progress meter.

     -r	     Recursively copy entire directories.

     -S program
	     Name of program to use for the encrypted connection.  The program
	     must understand ssh(1) options.

     -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.

DIAGNOSTICS
     scp exits with 0 on success or >0 if an error occurred.

     the University of California.
