Hi, I have written a small shell hack to lightly extend the output of df command.
It organizes data fields order differently and adds a small raw occupation bar to quickly view how full is each partition. It also skips header line and every root/tmpfs/devfs special partition.
The script only uses Busybox.

Here is the source code:
