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.
- -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
public key 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.
- -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 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.

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