As I discovered in practice, it seems to be a trend with authors of such small-size software to also forgo any kind of documentation: what options are supported by specific commands, what behaviours they exhibit (which sometimes differs between GNU and BSD). The ‘usage’ messages are also terse and cryptic to the max. Doubly baffling when the audience of the software is supposedly corporations building their userspace. Do the authors sell the docs on the side, or what?
Anyway, for users trying to do stuff with these utils, the available paths seem to be either finding StackOverflow answers from others who already messed with their own systems and survived, or being the first to do the trial-and-error.
