To install your own signal handler use the Signal function in 'linux'
unit like that:

var NewSignal, OldSigInt : SignalHandler;

procedure CatchSignal(aSig : Integer);cdecl;
begin
  case aSig of
    SIGQUIT : do_something1;
    SIGTERM : do_something2;
  end;
end;

...

NewSignal:=SignalHandler(CatchSignal);
OldSigInt:=Signal(SIDQUIT,NewSignal);
OldSigInt:=Signal(SIGTERM,NewSignal);
