On my system (Ubuntu MATE 20.04) there is no default file /etc/magic (per the man for "file").
My local definitions were placed in that file which are interpreted before other system definitions. The content of my "/etc/magic" file is as follows: # Magic local data for file(1) command. # Insert here your local magic data. Format is described in magic(5). 0 string %%Prolog Prolog Predicate File (Non-Specific) 0 string %%gprolog Prolog Predicate File (GNU Prolog) 0 string %%swipl Prolog Predicate File (SWI-Prolog) 0 string %%yap Prolog Predicate File (YAP Prolog) 0 string %%eclipse Prolog Predicate File (ECLiPSe) 0 string %%bprolog Prolog Predicate File (B-Prolog) 0 string %%poplog Prolog Predicate File (Poplog) 0 string %%lpaprolog Prolog Predicate File (LPA Prolog) 0 string %%isoprolog Prolog Predicate File (ISO-Compliant Prolog) 0 string [Pp][Rr][Oo][Ll][Oo][Gg] Prolog Predicate File (ISO-Compliant Prolog) 0 search :- Prolog Predicate File (Non-Specific :-) 0 search --> Prolog Predicate File (Non-Specific -->) # #0 search/2048 [Pp][Rr][Oo][Ll][Oo][Gg] Prolog Predicate File (ISO-Compliant Prolog) # #0 string % Prolog Predicate File (Non-Specific %) # # As can be seen, I was attempting to specify definitions which would identify the various dialects of Prolog and have "file" report those. Works splendidly for me!
