Not those exact strings, no. At least, not as far as I know. But "MB" is short for 1000*1000, and "M" for 1024*1024. > I saw that I could use other numerics, > even odd amounts, but nothing with an implied evaluation as the > description of SIZE starts off by saying. Sorry, don't follow. Perhaps an example would clarify? > I can see no rhyme or reason why I get lowercase K, or KB or > kB, etc. for the <ls> command, either. Again, I'm lost. Got a specific example? > The same goes for the statement on mandatory options. Just what is a > long option as compared to a short option? A long option is something like --ignore='*.x'. A short option is something like -I '*.x'. Typically, for every short option there's an equivalent long option, but the reverse is not necessarily true. > How do I know what is > mandatory from what isn't? Optional arguments are written in square brackets in the documentation, e.g., --color[=WHEN]. This isn't written down in the man page, unfortunately. It is described (not all that well) in the full manual, here: http://www.gnu.org/s/coreutils/manual/html_node/General-output-formatting.html#index-g_t_002d_002dcolor-791
