Figure 5: More uucp command examples

You can send a file to the remote system by using

uucp ~/transfer thumper!~/transfer.new

In this case, you are sending a copy of transfer to the system named
thumper, and renaming it to transfer.new on the remote system.

How about

uucp ~/stuff thumper!~

Copying a file from our system (unilabs) to the remote system, thumper.
This will read the file from PUBDIR, write it PUBDIR, while keeping the
same file name.
