UNIX for Dummies Questions & Answers

Outside this process I built a file containing snmp response filtering for hostname, model type and ios version.

I want to get a count across the network of those devices running 11.x code, 12.0 mainline, 12.0 T train and above, 12.1 and above and OS levels.

This works ok .. but its cheap

How can use case ? the obvious didnt work. I guess I dont know how to anchor the regex.

grep " 11\.[0-9]" seedfile$hf > 11_$hf
grep " 12\.0" seedfile$hf | grep "]$" > 12_0_$hf
grep " 12\.0" seedfile$hf | grep -v "]$" > 12_1_$hf
grep " 12\.[1-9]" seedfile$hf >> 12_1_$hf
grep " [1-9]\.[1-9]\{1,\}" seedfile$hf > 7_$hf

I don't understand what you want. Those grep's are not anchored.

Instead of doing all the greps, Id rather read through the file. I dont want to use ifs, I want to use case. Ifs are shown for a psuedo code explaination.

while read ip model ios hostname
do
case $ios in

if $ios is 11.0 print I have 11.0
if $ios is 12.0 mainline print I have 12.0
if $ios is 12.0 not mainline print I have 12.0 T or above
if $ios is single digit followed by a single digit it must be an os print I have an os

esac
done < seedfile
