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.
