Memorization is a necessity in every endeavour involving a process, even a computer is nothing without some form of memory. Like you remember powershell commands and switches and whatnot, I remember where executables are placed. It may be a convention, but that's only because a restriction hasn't been placed (yay, freedom?); for all practical purposes, it is a rule. Crossing fingers and hoping devs have followed a rule/convention/sensibility happens everywhere that isn't 100% under one's own control. Like I have to cross my fingers when installing from an .exe or .msi. > I'm guessing there is no solid convention for parsing a manpage to ... You guess wrong. (There is no convention for parsing a manpage, only for writing one, but isn't that enough?) > Everything above is tab-completable So it is in the *nix world. Check out oh-my-zsh (if bash's tab-completion wasn't enough for you), it has an option to enable a ridiculous (and annoying, IMO) amount of tab-completion.
