5.2.1.3 source

One or more source files. Wildcards are allowed. The syntax of wildcards depends on the system to which they apply, so if you are copying from a Windows system to a UNIX system, you should use Windows wildcard syntax (e.g. *.*), but if you are copying from a UNIX system to a Windows system, you would use the wildcard syntax allowed by your UNIX shell (e.g. *).

If the source is a remote server and you do not specify a full pathname (in UNIX, a pathname beginning with a / (slash) character), what you specify as a source will be interpreted relative to your home directory on the remote server.
