Shell Programming and Scripting

From the command line I am running the following command:

Code:

for i in $(awk '{print ($1)}' src-dst|uniq); do dig -x "$i" +short; done

src-dst has a list of IP addresses. When this script is running and I do a ps -ef | grep dig, I see the proper dig command with IP addresses being run, but the results do not display in stdout.
I tried redirecting dig with a > output and while output was created nothing was put in the file.

This works just fine for me:

Code:

i=8.8.8.8; dig -x "$i" +short

Result:

Code:

google-public-dns-a.google.com.

I hope this is enough information, any assistance would be appreciated.

Thank you for your time

Are you sure the IPs in the list resolve?

Thank you very much neutronscott. You are 100% right.

Sometimes it just takes making a fool of yourself to realize the obvious answer. I am on the wrong network and the addresses do not resolve where I am at.
