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_config(5). 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 can
be specified using scp -oProtocol=1.
-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.
scp exits with 0 on success or >0 if an error
occurred.

scp is based on the rcp(1) program in
BSD source code from the Regents of the University of California.
