not the 20 largest, but the 20 last modified.
the bash/watch commands sorts them alphabetically, i want to sort by time.
the solution i found still has a problem in that the tab character used
to align the columns does not overwrite anything in its space.
likewise at the end of the line, if the newly written line is shorter
then the remaining part of the old line is not cleared.
so i had to add some sed trickery to clear the path.
the ansi escape sequence "<esc>[K" clears the line before it is rewritten.
this has almost the same effect as clearing the screen, but without the flicker
clear
while true
echo \e\[H
for i in (ls -tr)
du -sh $i
end | tail -20 | sed -e 's/^/'\e'\[K/' | cut -c -(math $COLUMNS - 2)
sleep 2
end
