copies files between hosts on a network. It uses
for data transfer, and uses the same authentication and provides the same security as
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
treating file names containing
as host specifiers. Copies between two remote hosts are also permitted.
The options are as follows:
Forces
to use protocol 1.
Forces
to use protocol 2.
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.
Forces
to use IPv4 addresses only.
Forces
to use IPv6 addresses only.

Compression enable. Passes the
