On an x86-64 Linux system with SHELL=/bin/bash , du objects to the option
--max-depth=1 but du --help suggests it is allowed.
Evidence (with 5 empty spaces removed from the beginning of each line that
had them, so this email would not break lines unnecessarily):
miro[~]$ printenv | grep SHELL
SHELL=/bin/bash
miro[~]$ du --maxdepth=1
du: unrecognized option '--maxdepth=1'
Try `du --help' for more information.
miro[~]$ du --help | grep -A 1 depth
--max-depth=N print the total for a directory (or file, with --all)
only if it is N or fewer levels below the command
line argument; --max-depth=0 is the same as
--summarize
