scp - secure copy (remote file copy program) SYNOPSIS

scp [-pqrvBC1246 [-F ssh_config [-S program [-P port [unrenderable node] [-i identity_file [-o ssh_option [[

[user@

host1:]file1 [... [ [[user@ host2:]file2 DESCRIPTION

scp copies files between hosts on a network. It uses ssh(1) for data transfer, and uses the same authentication and pro- vides 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 datatransfer. 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 debug- ging messages about their progress. This is helpful in debugging connection, authentication, and configu- ration 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 the ssh(1) configuration file. 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.
