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 pro-
     vides the same security as ssh. Unlike rcp, scp will ask for
     passwords  or passphrases if they are needed for authentica-
     tion.

     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.

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

     -q    Turn off statistics display.

     -Q    Turn on statistics display.

     -r    Recursively copy entire directories.

     -v    Verbose mode.  Causes scp and ssh to  print  debugging
           messages  about  their  progress.   This is helpful in
           debugging connection, authentication,  and  configura-
           tion problems.

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

     -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 vari-
     ables. 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.
