Argument "E:/perl/scripts" isn't numeric in numeric ne (!=) at orphan_check.pl line 26
Of course this argument is not numeric because "E:/perl/scripts" is not a number, hence you were offered the operator 'ne' instead of the one you tried to use '!='.
You have to decide whether your operand(s) is in numeric context or a string context. In Perl it makes a difference and using an operator in a context that is it not applicable could give out such warnings.
'lt, gt, le, ge, eq, ne, cmp' perform on strings similar operations performed by '<, >, <=, >=, ==, !=, <=>' respectively on numbers
On a further note, be careful with treating strings as numbers because perl can force into a number any string that has been treated that way, an example will include using the arithmetic operators on strings, they will be reinitialized to zero..
my $string = "lion";
my $result = $string + 2;
print $result;
'$string' was reinitialized to 0... These are some errors that may just be hard to detect if you chose to ignore warnings given to you..
