— Secure copy (remote file copy
program] source ...
copies files between hosts on a network. It uses
for data transfer, and uses the same authentication
and provides the same security as ssh(1)
will ask for passwords or passphrases if they are needed
specified as a local pathname, a remote host with optional path in the form
], or a URI
in the form
Local file names can be made explicit using absolute or relative pathnames to
treating file names containing ‘:’ as
When copying between two remote hosts, if the URI format is used, a

if the -3
option is used.
The options are as follows:
- 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.
- Forces scp to use IPv4 addresses
- Forces scp to use IPv6 addresses
- Selects batch mode (prevents asking for passwords or
- Compression enable. Passes the -C flag to
ssh(1) to enable compression.
- 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
- Selects the file from which the identity (private key) for
public key authentication is read. This option is directly passed to
- 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 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 the file.
- Preserves modification times, access times, and modes from
the original file.
- Quiet mode: disables the progress meter as well as warning
and diagnostic messages from ssh(1).
- Recursively copy entire directories. Note that
scp follows symbolic links encountered in the tree
- Name of program to use for the
encrypted connection. The program must understand ssh(1)
- 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 filenames.
- Verbose mode. Causes scp and
ssh(1) to print debugging messages about their progress.
This is helpful in debugging connection, authentication, and configuration
