It's in "df" as well, praise Cthulu:

     aneurin# df -h
     Filesystem     Size    Used   Avail Capacity  Mounted on
     /dev/ad0s1a    496M    302M    154M    66%    /

     /dev/ad0s1e    989M    581M    329M    64%    /var
     /dev/ad0s1f    3.9G    2.2G    1.4G    62%    /home
     /dev/ad0s1g    8.9G    8.0G    127M    98%    /usr/local
     fdescfs        1.0K    1.0K      0B   100%    /dev/fd
     procfs         4.0K    4.0K      0B   100%    /proc

(Memo to self: see where all the room has gone in /usr/local, as that's where I 
assigned the leftover space after the other partitions.)

No, I've never liked stuffing everything under the root file system as both the 
Mac and Penguin do; fill the root file system and you're hosed (and I also have 
an itch about /tmp being there as it's a world-writable directory).

Years ago I wrote a simple script "lss" which did the sort after being
howled down on one of the FreeBSD lists; what a surprise to see "-S"...

Heck, back in my UNSW days I suggested extending stty() to cover non-TTY 
devices and got trashed by the AGSM/ElecEng mob; well well, look at ioctl() 
when it appeared.
