NAME
scp - secure copy (remote file copy program)SYNOPSIS
scp -words [-12346BCpqrv ] [-c cipher ] [-F ssh_config ] [-i identity_file ] [-l limit ] [-o ssh_option ] [-P port ] [-S program ] [[user @ ] host1 file1 ] ... [[user @ ] host2 file2 ]
DESCRIPTION
ssh 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). ssh 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 ssh treating file names containing `:' as host specifiers. Copies between two remote hosts are also permitted.
The options are as follows:
- -1
- Forces ssh to use protocol 1.
- -2
- Forces ssh 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 ssh to use IPv4 addresses only.
- -6
- Forces ssh 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.
- -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 ssh 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 ssh and ssh(1) to print debugging messages about their progress. This is helpful in debugging connection, authentication, and configuration problems.
