My sh shell script ability is not that good. Have 2 simple coding problems.
How do I code a statement to subtract one from a field. $rulenum = $rulenum - 1 $rulenum = '$rulenum - 1' one='1' $rulenum = $rulenum - $one $rulenum='$rulenum - $one' None of that works. must really be simple. I also have this line inruleno=`ipfw list | sed -n -e "s/00\([0-9]*\) $inblock/\1/p"` This works ok, the search argument is s/00\ but that is not good enough because the number can be 0 to 65535. The sed -n -e "s/00\([0-9]*\ needs to be changed to just return the first word. Thanks for any help you can give. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
