SCP(1)                   USER COMMANDS                     SCP(1)

NAME

     scp - secure copy (remote file copy program)

SYNOPSIS

     scp  [-12346BCpqrv]  [-c   cipher]   [-F   ssh_config]   [-i
     identity_file] [-l limit] [-o ssh_option] [-P port] [-S pro-
     gram] [[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 pro-
     vides the same security as ssh(1).  scp will ask  for  pass-
     words or passphrases if they are needed for authentication.

     File names may contain a  user  and  host  specification  to
     indicate  that  the  file is to be copied to/from that host.
     Local file names can be  made  explicit  using  absolute  or
     relative pathnames to avoid scp treating file names contain-
     ing `:' as host specifiers.  Copies between two remote hosts
     are also permitted.

     The options are as follows:

     -1   Forces scp to use protocol 1.

     -2   Forces scp to use protocol 2.

     -3   Copies between two remote hosts are transferred through
          the local host.  Without this option the data is copied
          directly between the two remote hosts.  Note that  this
          option disables the progress meter.

     -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 compression.

     -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  public key 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.

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

     -q   Quiet mode: disables the  progress  meter  as  well  as
          warning and diagnostic messages from ssh(1).

     -r   Recursively copy entire  directories.   Note  that  scp
          follows  symbolic links encountered in the tree traver-
          sal.

     -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.

EXIT STATUS

     Ex -std scp
