Question

I have a variable and am trying to pass in the following PW:

my $pass    = 'trAF\#\1cMax\$\';

Even though I'm escaping the # sign, its still thinking that the string ends with an F and causes an error as the code thinks its missing a semi-colon.

Be interested in any thoughts.

Answer 1

There's no problem with # . The only problem is that you're accidentally escaping the closing delimiter.

In single-quoted strings, you can only escape the delimiter and \\ because there's no need to escape anything else. You can even avoid escaping \\ if it's unambiguous, but that's not the case for the second \\ .

Both

my $pass = 'trAF#\\1cMax\\$\\';

and

my $pass = 'trAF#\1cMax\$\\';

assign the following string to $pass :

trAF#\1cMax\$\

---

If you meant to obtain the string

trAF#1cMax$

then all you need is

my $pass = 'trAF#1cMax$';
