There isn't much choice. If you are processing a file
then you should use file://$hostname/$pwd/$file
or if there is no filename (you are a pipe) then file://hostname/$pwd
and if you don't know your hostname you can leave it out
but of course you have to beware that the URIs you make in this way should
never go off the machine because they will of course like any filename
be confused with the same file on a different machine. This may of course
be what you want - on OSs which have conventional places to find particular
resources
like file:///etc/hosts.  But it is of course not generally recommended.

Don't use ftp: -- you are mapping a filename, and that is what file: means.
