Shell Programming and Scripting

I am attempting to gather data from 700 + routers. I have written a script that gets me about 70% of the information I need but I am in need of some assistance getting the remainder. I am fairly new to unix and I have not done programming since my 2nd year of high school in 1992.

I have a list of fqdn devices and the current script that I have takes the device name, verifies that it is in DNS, pings the ip, preforms an operation utilizing the Read only string and the Read write string for SNMP

The remaining data I need to gather lies in the Config file of the router.
I need to verify the following strings are defined in the config file (yes the communtiy strings and IP addresses have been altered for posting)


snmp-server host 192.36.0.231 public
snmp-server host 192.87.219.165 public config

Also verify the following ACL's are applied

access-list 23 permit 192.36.0.0 0.0.0.255 - (multiple networks)
access-list 23 permit 187.87.219.160 0.0.0.15
access-list 26 permit 167.36.0.0 0.0.0.255
access-list 26 permit 135.87.219.160 0.0.0.15


I want to store the information in variables to be output at the end of the script. I also need to match the IP listed in DNS to the interface it goes with on the router.

I am looking for output of yes or no.
example Variable $accces23 = yes if it is there or no if it is not found

Below is the current script that I have it works perfectly as it sits I just need the expanded data lines with (temporary edit) are a modification made tonight when my boss decided he wanted not only our fdqn name but the name the client assigns to the router. Any help would be great
