SCP(1) BSD General Commands Manual SCP(1)
scp — secure copy
(remote file copy program)
[−S program] [
[user@]host1: ]file1 ... [
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.
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.
The options are
scp to use protocol 1.
scp to use protocol 2.
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

Selects the cipher to use for
encrypting the data transfer. This option is directly passed
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).
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
Specifies the port to connect
to on the remote host. Note that this option is written with
a capital ’P’, because −p is

diagnostic messages from ssh(1).
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
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
Causes scp and ssh(1) to print debugging messages
about their progress. This is helpful in debugging
connection, authentication, and configuration problems.

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