partially:
" du [-A] [-H | -L | -P] [-a | -s | -d depth | -t threshold] [-c] [-l]
[-h | -k | -m | -B blocksize] [-n] [-x] [-I mask] [file ...]"
1) [-H | -L | -P] is correct
2) [-a | -s | -d depth | -t threshold] is not correct. the -t option can be
used together with the -a, -s and -d options.
3) [-h | -k | -m | -B blocksize] is not correct. the -B option can be used
together with the -h, -k and -m options.
also style(9) describes "|" as "either-or" operator. for the -h, -k and -m
options this isn't true. they can very well be used in a single command, but
the last option backs out all the previous ones.
i think the following would be better:
" du [-Achklmnx] [-H | -L | -P] [-a | -s | -d depth] [-B blocksize]
[-I mask] [-t threshold] [file ...]"
and the paragraph
" The -h, -k and -m options all override each other; the last one specified
determines the block count used."
cheers.
