SCP(1) BSD General Commands Manual SCP(1)
scp — OpenSSH secure file copy
scp [-346BCpqrTv] [-c cipher] [-F ssh_config] [-i identity_file]
[-J destination] [-l limit] [-o ssh_option] [-P port] [-S program]
source ... target
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). scp will ask for passwords or passphrases if they are
needed for authentication.
The source and target may be specified as a local pathname, a remote
host with optional path in the form [user@]host:[path], or a URI in the
form scp://[user@]host[:port][/path]. Local file names can be made
explicit using absolute or relative pathnames to avoid scp treating
file names containing ‘:’ as host specifiers.
When copying between two remote hosts, if the URI format is used, a
port may only be specified on the target if the -3 option is used.
The options are as follows:
-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 and selects batch mode for the second host,
since scp cannot ask for passwords or passphrases for both
hosts.
-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 pub‐
lic key authentication is read. This option is directly passed
to ssh(1).
-J destination
Connect to the target host by first making an scp connection to
the jump host described by destination and then establishing a
TCP forwarding to the ultimate destination from there. Multi‐
ple jump hops may be specified separated by comma characters.
This is a shortcut to specify a ProxyJump configuration direc‐
tive. 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 pro‐
gram must understand ssh(1) options.
-T Disable strict filename checking. By default when copying
files from a remote host to a local directory scp checks that
the received filenames match those requested on the command-
line to prevent the remote end from sending unexpected or
unwanted files. Because of differences in how various operat‐
ing systems and shells interpret filename wildcards, these
checks may cause wanted files to be rejected. This option dis‐
ables these checks at the expense of fully trusting that the
server will not send unexpected filenames.
-v Verbose mode. Causes scp and ssh(1) to print debugging mes‐
sages about their progress. This is helpful in debugging con‐
nection, authentication, and configuration problems.
The scp utility exits 0 on success, and >0 if an error occurs.

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