I am attempting to get a script borrowed from DJB to work on my
CentOS-6.6
box. Simplified it looks like this:
tcpdump -l -n -e port 53 \ | awk '{if ($14 ~ /A.*?/) print $15}' \ | while read domain ; do echo $domain ; done ;
The sticking point is the 'while read' construct. Run just as 'tcpdum |
awk'
I get this:

Run with the 'while read $domain ; do echo ' pipe nothing appears
whatsoever.
What am I doing wrong?
