Though if you write --markov= and then TAB, I presume it will write all that to your line. Still, I think this would be a good addition. A similar approach could be used for -users, -groups, -shells and -salts. > Unfortunately, I can't (or don't know yet how to) add "(see doc/MARKOV > for details)" to the tab completion options, because this would be > interpreted as separate completion options which get dropped because the > (to be completed) word "--markov" existing on the command line doesn't > match the other "options". Perhaps you could do this: $ ./john --markov --markov --markov[=LEVEL[:START[:END[:LENGTH]]]] This is even better than the usage blob, where this is too long to fit. magnum
