If you change my $rvar = "\$interface"; To my $rvar = '\$interface'; It works like I think you want it to. The reason it wasn't working before is because the regex was seeing: $cmd =~ s/$interface/test/; Because when you declared $rvar, it saved the string '$interface', which then got interpolated by the regular expression.
