Get value in single quote Can't Post
I am trying to create a script in linux but facing some problem.

In single quote, i cannot get any value from outside as per rule.

Suppose my raw data is

134 PTR server1.example.com.
135 PTR server2.example.com.

and i want to change it to

134.0.168.192.in-addr.arpa. PTR server1.example.com.
135.0.168.192.in-addr.arpa. PTR server2.example.com.

below value get always change

0.168.192

so i have set one variable i.e.

VALUE=0.168.192

if i use this command then it is not taking value. Can we achieve this with perl ?

cat file.txt | awk '{print $1".$VALUE.in-addr.arpa.", $2, $3}'

so please suggest

What about using double quotes?

Something like: $value = "0.168.192";

perl -pe 's/^(\d+)/$1.0.168.192.in-addr.arpa/' file.txt
