SCP(1) BSD General Commands Manual SCP(1)
NAME
scp -- secure copy (remote file copy program)
SYNOPSIS
scp [-1246BCEpqrv] [-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.
Any file name may contain a host and user specification to indicate that the file is to be copied
to/from that host. Copies between two remote hosts are 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 passphrases).
-C Compression enable. Passes the -C flag to ssh(1) to enable compression.
-E Preserves extended attributes, resource forks, and ACLs. Requires both ends to be running Mac
OS X 10.4 or later.
-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 RSA 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 Disables the progress meter.
-r Recursively copy entire directories.
-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.

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