Regex password length

Hi all,

I'm trying to create a regex to ensure a minimum password length.

I'm trying this:

$regex= '^.{4,}$'

That work fine exept for, at least, the equal signal (=)

For example, if i try 'my=test", it returns false. If i try 'myte=st',
that works.

If i change 4 for 2 in regex, then the first example works (my=test)

Look like the repetition part doesn't work at all with equals...

Any idea about that problem? Any solution?

Thanks in advance

Alfonso.

It would seem that you should use the length function. (Also, why
should it matter that the string in question is a password?)

Maybe you need qr// ?

No, I don't think so. The pattern you're giving should match both. Can
you show us the code that does what you're talking about?

print "matched\n" if 'my=test' =~ /^.{4,}$/;
print "matched\n" if 'myte=st' =~ /^.{4,}$/;

Cheers!

Resolved. All works as spected. The problem was that the source string
wasn't the correct one, not the regex. Was a stupid mistake.

Thanks any way for the reply
