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.
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:
-c cipher
Selects the cipher to use for encrypting the data transfer.
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).
-p
Preserves modification times, access times, and modes from the
original file.
-r
Recursively copy entire directories.
-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.
-B
Selects batch mode (prevents asking for passwords or passphrases).
-q
Disables the progress meter.
-C
Compression enable.
Passes the
-C
flag to
ssh(1)
to enable compression.
-F ssh_config
Specifies an alternative
per-user configuration file for
ssh
This option is directly passed to
ssh(1).
-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).
-S program
Name of
program
to use for the encrypted connection.
The program must understand
ssh(1)
options.
-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 example, forcing the use of protocol
version 1 is specified using
scp -oProtocol=1
-1
Forces
scp
to try protocol version 1 only.
-2
Forces
scp
to try protocol version 2 only.
-4
Forces
scp
to use IPv4 addresses only.
-6
Forces
scp
to use IPv6 addresses only.
DIAGNOSTICS
scp
exits with 0 on success or >0 if an error occurred.
