I was going to suggest something like this in order to overcome the 5% error due to the ext3fs reserved blocks.
Code:
display `df /dev/sda2 |awk '(/^\/dev/){printf ("%d%%\n",$3/$2 * 100)}'`cut is cheating
or I'd have suggested...
Code:
df -h /dev/sda2 | grep /dev/sda2 | cut -c 52-55
True, but I used sed to replace tr : )cut is cheating
Code:
humax# df -h /dev/sda2 | sed '1d;s/.* \([0-9]*%\).*/\1/'
49%

Careful, af will take exception and tell you it's bash or something, not Linux!
Well, in this case mostly sed : )
Don't learn bash, learn Bourne shell (sh). You can always learn the Bash extensions later.

I'm tired of people coming for interview for jobs involving shell programming (we don't use bash) and not realising the difference!
They're the same people who almost invariably tell us that our "Up arrow is broken"* and the "Cursor keys aren't working in vi" (and also tend to pronounce vi as in vie instead of Vee Eye).

* - we aren't allowed to use any shell with a history due to security policy constraints.

Fortunately I'm the chap who enforces security policies so I don't have to worry about conforming to them.
