Regex match in shell script -

-

i'm writing shell script makes sure dns server looking. here's output tests:

server:         127.0.0.1 address:        127.0.0.1#53  name:   galapagos.office address: 192.168.140.25

everything "galapagos.office" needs match exactly. "galapagos.office" part doesn't matter @ all.

i figure can apply regex output tell me if looks how want:

server: +127\.0\.0\.1\naddress: +127\.0\.0\.1#53\n\nname:.+\naddress: 192\.168\.140\.25

the thing don't know shell scripting. what's best way make sure regex matches output of nslookup command?

just guess of want

awk '/server/&&$2=="127.0.0.1"{f=1}        /address/&&$2=="127.0.0.1#53"{g=1}        /address/&&$2=="192.168.140.25"{h=1}   end{if(h && g && f) print "ok"}' file
