This is because you use only the first argument "$1" in
your script.
The globbing happens before your script gets started.
The shell parser converts your command
enscript+ *
to a list of arguments
enscript+ file1 file2 ...
which your script gets to see as
"$0" "$1" "$2" ...
As i wrote a few days ago, "$@" (with quotes around it) gives
you the list of arguments: "$1" "$2" ...
According to its man page, enscript is willing to take more
than one filename. So may simply write
enscript --media=letter -2 --landscape --borders \
--header='$n|A.D. $D{%Y.%m.%d}|$* gmt | Page $% of $=' "$@"
If enscript would only take one filename per run, you
would have to execute it several times in a loop:
for i in "$@"
do
enscript --media=letter -2 --landscape --borders \
--header='$n|A.D. $D{%Y.%m.%d}|$* gmt | Page $% of $=' "$i"
done
This would also be the way to go if enscript concatenates
all filenames of a run to a single output file whereas
you might want several output files.
Another way of handling an argument list of variable length
is the variable "$#" which gives the number of arguments
and the command "shift" which deletes "$1" and shifts "$2"
to "$1", "$3" to "$2", and so on. It also counts down "$#".
So you always use "$1" and give it new values by "shift":
while test "$#" -ge "1"
do
enscript --media=letter -2 --landscape --borders \
--header='$n|A.D. $D{%Y.%m.%d}|$* gmt | Page $% of $=' "$1"
shift 1
done
Have a nice day :)
