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 secu-
     rity 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 explicit using absolute or relative pathnames to avoid scp treating file names containing ':' as host specifiers.  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.

     -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 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 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.

HISTORY

     scp is based on the rcp(1) program in BSD source code from the Regents of the University of California.
