Removing non-numeric character from output

Hi All,

On my SunOS 5.9 devbox:

The output of:  df -k |grep /dev/dsk/c0t0d0s0|tail -1|awk '{print $5}'
is:  76%

I need to remove the trailing % sign, as I want to assign this value to a varianble (and then us it in a script to send out notifications)

How do I remove the % from the output?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

There are many many ways of doing this. This was the first one I could think of  but might be a bit of an overkill.

df -k |grep /dev/dsk/c0t0d0s0|tail -1|awk '{print $5}'  |  sed -e 's/%//g'
