SCP(1)                     OpenBSD Reference Manual                     SCP(1)

NAME
     scp - secure copy (remote file copy program)

SYNOPSIS
     scp [-1246BCpqrv] [-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).  Unlike rcp(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 ex-
     plicit 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.

     -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 passphras-
             es).

     -C      Compression enable.  Passes the -C flag to ssh(1) to enable com-
             pression.

     -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 in
             rcp(1).

     -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 sym-
             bolic 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.

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