Top Forums Shell Programming and Scripting ksh - Need Help Reducing Nested Loops Post 302922271 by Azrael on Thursday 23rd of October 2014 01:41:08 PM

As I mentioned I'm trying to remove the for loop with "j" and "ls -l | awk '{ print $9 }'". Originally I was going to loop through multiple files, but have decided there are better ways to do this.

The lists contain thousands of lines of many different ip ranges. Since the pf firewall does not handle ranges outside CIDR, I'm using sed to remove the text in lines like these that are not ips and drop the hyphen between the ips:

Marchex, Inc:8.20.104.0-8.20.107.255

Then I used the B variable to hold the last octet of the first ip and C to hold the last octet of the second ip. D holds the first three octets of the ip addresses. After that the last while loop writes the individual ip address to a file to be used for a table in pf.

I'm sure there are easier and better ways to do a lot of this. I just thought I'd focus on one thing and not bother anyone with totally overhauling this. However, I'm open to any and all suggestions. As this was my first Ksh, its very convoluted and not where I'd like it to be. Thanks
