SCP(1)                             BSD General Commands Manual                             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 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 writ-
             ten 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 encoun-
             tered 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 configura-
             tion problems.

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