scp

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

NAME

     scp -- secure copy (remote file copy program)

SYNOPSIS

     scp [-pqrvBC46] [-F ssh_config] [-S program] [-P port] [-c cipher] [-i identity_file] [-o ssh_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 secu-
     rity 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 compression.

     -F ssh_config
	     Specifies an alternative per-user configuration file for ssh.  This option is directly passed to ssh(1).

     -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 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 example, forcing the use of protocol version 1 is specified using scp -oProtocol=1.

     -4      Forces scp to use IPv4 addresses only.

     -6      Forces scp to use IPv6 addresses only.

DIAGNOSTICS

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

AUTHORS

     Timo Rinne <tri@iki.fi> and Tatu Ylonen <ylo@cs.hut.fi>

HISTORY

     scp is based on the rcp(1) program in BSD source code from the Regents of the University of California.
