# df --help
usage: df [-HPkhi] [-t type] [FILESYSTEM ...]

The "disk free" command shows total/used/available disk space for
each filesystem listed on the command line, or all currently mounted
filesystems.

-a      Show all (including /proc and friends)
-P      The SUSv3 "Pedantic" option
-k      Sets units back to 1024 bytes (the default without -P)
-h      Human readable output (K=1024)
-H      Human readable output (k=1000)
-i      Show inodes instead of blocks
-t type Display only filesystems of this type

# du --help
usage: du [-d N] [-askxHLlmc] [file...]

Show disk usage, space consumed by files and directories.

Size in:
-k      1024 byte blocks (default)
-K      512 byte blocks (posix)
-m      megabytes
-h      human readable format (e.g., 1K 243M 2G )

What to show:
-a      all files, not just directories
-H      follow symlinks on cmdline
-L      follow all symlinks
-s      only total size of each argument
-x      don't leave this filesystem
-c      cumulative total
-d N    only depth < N
-l      disable hardlink filter
