scp - secure copy (remote file copy program)
scp [-prvBC]
[-S path-to-ssh] [-o ssh-options] [-P port] [-c cipher] [-i identity] [[user@]host1:]filename1...
[[user@]host2:]filename2
Scp copies files between hosts
on a network. It uses ssh for data transfer, and uses the same authentication
and provides the same security as ssh. Unlike rcp, 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.
- -c cipher
- Selects the cipher to use for encrypting the data
transfer. This option is directly passed to ssh.
- -i identity_file
- Selects
the file from which the identity (private key) for RSA authentication
is read. This option is directly passed to ssh.
- -o ssh-options
- Ssh options
passed to ssh.
- -p
- Preserves modification times, access times, and modes
from the original file.
- -r
- Recursively copy entire directories.
- -v
- Verbose
mode. Causes scp and ssh 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).
- -C
- Compression enable. Passes the -C flag to ssh to enable compression.
- -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.
- -S path-to-ssh
- Specifies
the path to ssh program.

Scp is based on the rcp program in BSD source code
from the Regents of the University of California.
