Grep a number from a line in ksh
In file.name, I have a line that reads

$IDIR/imgen -usemonths -dropcheck -monitor -sizelimit 80000000 -interval 120 -volcal HSI

How can I get the size limit, i.e. 80000000 out and pass it to a variable called SIZE?

Thanks. I tried
echo "grep sizelimit file.name" | sed -n -e 's/^.sizelimit\([0-9]*\) -interval.*$/\1/p'

but it output nothing.
