Got it.Then your script is may right.
The only note is the meta-characters.becase '.' is a meta-character in Perl,so
given this case:
$source_ip = '192.168.1.1';
$dest_ip = '10.0.0.1';
s/$source_ip/$dest_ip/g;
maybe meet some problems.
The better way is use \Q for disable quote meta-characters.like:
s/\Q$source_ip/$dest_ip/g;
>From perldoc perlre:
\E end case modification (think vi)
\Q quote (disable) pattern metacharacters till \E
Hope this useful.
