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.
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.
-A Allows forwarding of ssh-agent(1) to the remote system.
The default is not to forward an authentication agent.
-B Selects batch mode (prevents asking for passwords or
-C Compression enable. Passes the -C flag to ssh(1) to enable
Selects the cipher to use for encrypting the data transfer.
This option is directly passed to ssh(1).
Specifies an alternative per-user configuration file for
ssh. This option is directly passed to ssh(1).
Selects the file from which the identity (private key) for
public key authentication is read. This option is directly
passed to ssh(1).
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. Multiple jump hops may be
specified separated by comma characters. This is a
shortcut to specify a ProxyJump configuration directive.
This option is directly passed to ssh(1).
Limits the used bandwidth, specified in Kbit/s.
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).
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
-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.
Name of program to use for the encrypted connection. The
program 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 operating systems and shells interpret filename
wildcards, these checks may cause wanted files to be
rejected. This option disables these checks at the expense
of fully trusting that the server will not send unexpected
-v Verbose mode. Causes scp and ssh(1) to print debugging
messages about their progress. This is helpful in
debugging connection, authentication, and configuration
