Compare resolv.conf IP with given IP as input

Aniruddhaaaaaaa · 05-22-2018, 04:21 PM

I want to input IP (may be 2 or 3 IPs)
It will compare that IP with the IP present in resolv.conf.
If all IP present then output should be good else it will show the resolv.conf file content.

What have you tried?
Sounds like you want to read one or more IP addresses, grep each to see if in resolv.conf, and report accordingly.

Wonder why you don't just look at the contents of resolv.conf? What problem are you trying to solve?

I need to check that IPs are present in resolv.conf for multiple server or not through one command by SSH

Ok...so you'll have to write a script. Just restating your question doesn't tell us anything new; read the "Question Guidelines" and "How to ask a smart question" links in my posting signature.

Again, post what you have written/done/tried so far and we'll be happy to help, but we aren't going to write a script for you. You also have to define things, such as saying where the input IP addresses are coming from, etc.
