scp copies files between hosts on a network.

scp

It uses ssh for data transfer, and uses the same authentication and provides the same security as a login session.

scp will ask for passwords or passphrases if they are needed for authentication.

The source and target may be specified as a local pathname, a remote host with optional path in the form [user@]host:[path], or a URI in the form scp://[user@]host[:port][/path].

Local file names can be made explicit using absolute or relative pathnames to avoid scp treating file names containing ‘:‘ as host speacifiers.

When copying between two remote hosts, if the URI format is used, a port cannot be specified on the target if the -R option is used.

Options	Implication
`-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.
`-4`	Forces `scp` to use IPv4 addresses only
`-6`	Forces `scp` to use IPv6 addresses only
`-A`	Allows forwarding of ssh-agent(1) to the remote system. The default is not to forward an authentication agent.
`-C`	Compression enable
`-l`	Limits the used bandwidth, specified in Kbit/s
