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.
Any file name may contain a host and user specification to indicate
that the file is to be copied to/from that host.
Copies between two remote hosts are 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 RSA
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 in
rcp(1).
- -p
-
Preserves modification times, access times, and modes from the
original file.
- -q
-
Disables the progress meter.
- -r
-
Recursively copy entire directories.
- -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.
