Disk usage for hoomans - duh

Duh4 is the 4th version of this trick and it seems the fastest one, to get most speed remove the call to ‘other’.

Even faster variant would be to use rust dust and alias like:

alias duh5='dust -c -b -d 1'
# or more advanced
alias duh5='dust -c -b -d 1 . | sed "s/[^[:alnum:]+-. ]//g" && df -h .'

(But this will only print stuff when everything is calculated).
