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 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).  scp will ask for passwords 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 containing ‘:’ 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 traversal.

       -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

       The scp utility exits 0 on success, and >0 if an error occurs.
