^^^^^
Those characters don't appear in the string below.

-My-Kills-Wed-Thu-Fri-Sat-Sun-

What have you tried, and how did it fail?

I am assuming you mean how to remove the beginning and ending "-" character
from the string. This is how:

#!/usr/bin/perl
use strict;
use warnings;

my $string = "-My-Kills-Wed-Thu-Fri-Sat-Sun-";
$string=~s/^-(.*)-$/$1/;
print $string;

You would be better off using Ruby:

s='-My-Kills-Wed-Thu-Fri-Sat-Sun-'
s.gsub!( /^-|-$/, '' )
puts s
