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.
-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 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.
The scp utility exits 0 on success,
and >0 if an error occurs.
scp is based on the rcp(1) program in
BSD source code from the Regents of the University of California.
