Dear Sean,
No, there isn't. You'd have to parse the df output to get that
value. I suggest using the -P switch to df, so you don't have to deal
with multi-line output per filesystem.
The following will return kilobytes of disk space used (third column
in the df -kP output):
df -kP |grep -v ^Filesystem |awk '{sum += $3} END { print sum; } '
Best,
-at
