[texhax] Running tex from a command line

I have not run tex other than from a command line ever.  When I install texlive from CTAN (although I just got a disk from tug, it is useless as my computers don't have readers) it adds it to the path.  I can certainly say on the command line
latex filename, but I actually have three tiny batch files.  Each one looks to see if a filename is supplied.  If it is, it sets a variable dfile = filename (no filetype).  If not, it uses dfile.  The other batch files load my editor and load the pdf reader (I use Sumatra.pdf), all using (or setting) the dfile.  This is under Windows (although it goes back to my DOS days) and cannot be implemented under any version of Linux I have ever tried since there is no way to set the dfile that doesn't go away when the batch file terminates.

To be more precise. \babelhyphen{nohyphen} does the job, but
hyphenation points at ordinary "-"s are still there. So, as far as I
conclude from my humble experiments, only a combination of a lua
filter (to disable all hyphenations at -) and a special command (to
enable hyphenation of compound words everywhere except at -) does the
whole job.

Please consider this core. Two questions:
1. will lua filter do any harm?
2. can you think of any improvements or this concept?


no_hyphenation_points = function (head)
  for n in node.traverse(head) do
    if (n.id == node.id('glyph') and n.char == 0x2d and n.next.id ==
node.id('disc')) then
  return head
