You answered just one of the questions. Please read the whole text.
For each question in Ben's posting provide a sensible answer. Then
there will be a chance to help you.

That's not quote what I meant, but it tells me lots anyway. The $1 only
works if you put the commands in a script or function.

On the command line, your shell may give you a way to refer to a
previously typed file name, but I don't know what shell you are using.
Anyway, I think it is simpler to put the commands into a function. You
can load it every time you start a shell by putting it in one of the
init files for your shell (again I can't say exactly where).

I don't know OSX (if the file names are anything to go by I am glad I
don't!) but just be sure that the two names you are using for the file
do indeed refer to the same file.

Shouldn't || be && ? You want to remove the source if the conversion
was successful.

With ||, the second command won't be executed if the first one was
successful.
