How to use system command in a perl script with sudo?

Question

I would like to use this in my perl script:

sudo killall -HUP tor

would this work?:

system echo sudo killall -HUP tor

Also how would I get around having to authenticate when running the script/from within the script?

You're solving the wrong problem. See Perl's kill function (perldoc -f kill, man perlipc). — waltinator, Jan 22 '17 at 18:08
@waltinator Are you interested in posting an answer about that? As felwithe has also mentioned, I think what you've suggested here is probably the way to go. — Eliah Kagan, Apr 27 '18 at 17:00

You could, although your syntax is wrong. The correct syntax would simply to use sudo with any of Perl execution methods:

system "sudo command";
`sudo command`;
exec "sudo command";

But like the comments above point out, it's probably not what you want to do to solve the problem you're trying to solve.
