DESCRIPTION
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).
Unlike
rcp(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 as follows:
- -1
-
Forces
scp
to use protocol 1.
- -2
-
Forces
scp
to use protocol 2.
- -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_config5.
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_config5.

-
- -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 in
rcp(1).
- -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.
Ex -std scp
