    Here "$1" means "for the first argument"
   If enscript can work with several files together, you cn substitue "$1"
simply
  by "$@"
  If however enscript can only work one file at a time, you can do the
following:

for f in "$@"
do
  <same enscript line substituting "$f" for "$1">
done

     Hope this helps.

Thanks.  A week or so ago I asked for help, because enscript was not
seeing changes which I made to the configuration file in order to change
the margins and customize headings; that I why I ended up putting the
customization into a bash script "enscript+".

However, just now, when I executed "enscript *" on a directory of files,
to see whether the unmodified package could handle globs, all of the files
printed properly, together with the customized headers!  So now I am
confused, but at least I am able to use the glob "*" and have the headers
and margins which I desired.

Thanks.
