Yeah, but perhaps I should have used sed instead of the second awk;
fewer processes:

du -h | awk '{a[i++]=$0} END {for (j=i-1; j>=0;) print a[j--] }' | sed
-e 's,^[^1-9]*\([^___CTRL-V+TAB______]*\)____CTRL-V+TAB_____*\(.*\)$,\2
\[\1\],;s,[^-][^/]*/,--,g;s,^,|,'

That does exactly the same --  where I've put ____CTRL-V+TAB______ you
have to type Ctrl-V, then a literal [::tab::] key; BSD sed doesn't do
\t.
