Or you can do it the long, slow wasteful way, which us dullards are required
to use, so we can figure out why it broke yet again.

#!/bin/bash
let c=0;
# get the number of fields
for i in `mount -p | tail -1`; do let c=$c+1; done

# if number of fields is greater than 3 because mount point has a space, 
add them
CUT_FIELDS="--fields=1"
let i=3;
while [ $i -lt $c ]
do
CUT_FIELDS=$CUT_FIELDS,$i
let i=$i+1
done

# get the fields
mount -p | tail -1 | /usr/bin/cut --delimiter=" " $CUT_FIELDS
