Launch gprolog with sh

[Paolo Parise]

Hi,

I'm writing a script (.sh) which should launch gprolog, load a file (wumpusMind.pl) and the initial query (init) in the same file which is in the form:

init :-
    retractall(counter(_)),
    ...

but there's something wrong (it seems in the consulting of name.pl):
gprolog --consult-file wumpusMind.pl --entry-goal 'init, nl'
(error message:)

address@hidden:~/Desktop$ sh lauch.sh 
GNU Prolog 1.3.0

warning: command-line goal 'init, nl' caused exception: error(existence_error(procedure,init/0),'command-line')
| ?- 

Manually I do the follow:
gprolog
| ?- [name]
| ?- init.
... processing

Have you got a clue?

Thanks in advance!
