The extended regular expression ^(1.|.)..$ seems to do what you want. But without knowing what utility you're using to evaluate the RE, I have no idea if it will do what you want.
Your thread title mentions regexp; your text mentions pattern. If you want a pathname matching pattern instead of a regular expression, you need something completely different.

test::unit::assertion::regexp
Test::Unit::Assertion::Regexp(3pm) User Contributed Perl Documentation Test::Unit::Assertion::Regexp(3pm)
NAME
Test::Unit::Assertion::Regexp - Assertion with regex matching
SYNOPSIS
require Test::Unit::Assertion::Regexp;
my $assert_re =
Test::Unit::Assertion::Regexp->new(qr/a_pattern/);
$assert_re->do_assertion('a_string');
This is rather more detail than the average user will need. Test::Unit::Assertion::Regexp objects are generated automagically by
Test::Unit::Assert::assert when it is passed a regular expression as its first parameter.
sub test_foo {
...
$self->assert(qr/some_pattern/, $result);
}
If the assertion fails then the object throws an exception with details of the pattern and the string it failed to match against.
Note that if you need to do a 'string does not match this pattern' type of assertion then you can do:
$self->assert(qr/(?!some_pattern)/, $some_string)
ie. Make use of the negative lookahead assertion.
IMPLEMENTS
Test::Unit::Assertion::Regexp implements the Test::Unit::Assertion interface, which means it can be plugged into the Test::Unit::TestCase
and friends' "assert" method with no ill effects.
DESCRIPTION
The class is used by the framework to provide sensible 'automatic' reports when a match fails. The old:
$self->assert(scalar($foo =~ /pattern/), "$foo didn't match /.../");
seems rather clumsy compared to this. If the regexp assertion fails, then the user is given a sensible error message, with the pattern and
the string that failed to match it...
