Which ksh are you running (/usr/local/bin/ksh{,93)) ?

If you are really new to this sort of things, test them interactively
with 'set -ux' options.

BTW., it gave me a thing like this on 4.9-STABLE with /usr/local/bin/ksh.


% ksh
$ SW_USED=1
$ SW_TOTAL=3
$ PERCENT_USED=$(bc <<EOF
> scale=4
> ($SW_USED / $SW_TOTAL) * 100
> EOF
> )
$ echo $PERCENT_USED
33.3300
$ ^D
