NAME
  scp -	secure copy (remote file copy program)


SYNOPSIS

  scp [-aAqQprvBCL1] [-S path-to-ssh] [-o ssh-options] [-P port] [-c cipher]
  [-i identity]
       [[user@]host1:]filename1...  [[user@]host2:]filename2


DESCRIPTION

  Scp copies files between hosts on a network.	It uses	ssh for	data
  transfer, and	uses the same authentication and provides the same security
  as ssh. Unlike rcp, 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.


OPTIONS


  -a	Turn on	statistics display for each file.

  -A	Turn off statistics display for	each file.

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

  -i identity_file
	Selects	the file from which the	identity (private key) for RSA
	authentication is read.	 This option is	directly passed	to ssh.

  -L	Use non	privileged port. With this you cannot use rhosts  or
	rsarhosts authentications, but it can be used to bypass	some
	firewalls that dont allow privileged source ports to pass. Same	as
	saying "-o UsePriviledgePort=no" or -P to ssh; -L is used due to
	exhaustion of suitable letters.

  -1	Force scp to use command "scp1"	on the remote side instead of "scp".
	This may be necessary in some situations, if the remote	system has
	"scp2" symlinked to "scp".

  -o ssh-options
	Ssh options passed to ssh.


  -C	Compression enable.  Passes the	-C flag	to ssh to enable compression.

  -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.

  -S path-to-ssh
	Specifies the path to ssh program.


ENVIRONMENT VARIABLES

  You can turn scp statistics on or off	by setting SSH_SCP_STATS or
  SSH_NO_SCP_STATS environment variables. To turn on or	off scp	statistics
  for each file, use SSH_ALL_SCP_STATS or SSH_NO_ALL_SCP_STATS environment
  variables. The default value of the statistics can be	set when the ssh is
  configured. Next the scp checks those	environment variables and after	that
  command line options.
