Converting string to number in ksh script?

MAD_2 — Sat, 30 Mar 2002 16:20:53 GMT

Can anyone tell me how to convert the result from a series of commands from string to number in order to use these results with arithmetic operands?

i.e.

bdf| grep /tmp | awk '{print $5}'| cut -c1,2

How to I convert the string result to number in a script?

Thanks,

Hi again

what you are trying to do here will fail if the disk uasge is below 10% try this instead

answer=$(bdf| grep /tmp | awk '{print $5}'| sed -e 's/%//g')

expr $answer

Thanks John, I did not even think about that possibility, but it certainly wouldn't work in that case.
