Re: how to query goal in OS shell ?

Hi,

you can use:

gprolog --init-goal 'bar(1,2)' --init-goal 'halt'

or simply:

gprolog --init-goal 'bar(1,2),halt'

NB: there is no final doc in the agreement of the --init-goal option.

Look at the doc for other options (--entry-goal or --query-goal) depending on you want or not the starting banner. 

Try gprolog --help

Look at the doc
