Why wouldn’t it be safe? Many scripts I have are only available internally so don’t need to worry about people hacking them (unless they want to risk being fired to look at say syslog messages without having to ssh into the box). Perl -T helps ensure there’s no tainting of variables - you take the parameter that’s passed and regex pull out the matching pattern you need to use. If your variable is a match of ([\d]+) then it’s only going to have numbers in, and you can use it fairly safely
