Hi All,
I have the following command which returns the output like this -
wget URL|grep hostname|awk '{print $1,$3}'|/usr/bin/perl -nle 'm{"(.*?)".*?//(.*):(\d+)/} and print "$1 $2 $3"'|while read host port
do
echo check_env_$port
echo host
done
OUTPUT
Appname hostname port
Appname2 hostname port2 ...
Appnames are all unique , while hostname is not since I am grepping for single hostname(vip).
Some of the ports are not unique so I am getting the same port for 4-5 different appnames.
Within the same snippet of code I want to add a number to echo command so the its unique..
e.g. check_env_1_1234
check_env_2_1234
So for port 1234 it should increment the numbers.
If that's too hard then atleast get unique entries so that I don't get check_env_1234 not more than once which ever comes first and ignore the rest of the entries with the same port.
Thanks,
Jack.
