SCP(1)                    BSD General Commands 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 authentica-
     tion.

     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 speci-
     fiers.  Copies between two remote hosts are also permitted.

     When copying a source file to a target file which already exists, scp will replace
     the contents of the target file (keeping the inode).

     If the target file does not yet exist, an empty file with the target file name is
     created, then filled with the source file contents.  No attempt is made at "near-
     atomic" transfer using temporary files.

     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 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 authen-
             tication 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).

                   VerifyHostKeyDNS

     -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 symbolic links
             encountered in the tree traversal.

     -S program
             Name of program to use for the encrypted connection.  The program must under-
             stand 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 con-
             figuration problems.

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

IPV6
     IPv6 address can be used everywhere where IPv4 address. In all entries must be the
     IPv6 address enclosed in square brackets. Note: The square brackets are metacharac-
     ters for the shell and must be escaped in shell.

HISTORY

     sity of California.
