You are correct in correcting me; not every line is added. However, if, like he original problem, substrings can precede their superstrings, then your suggestion is inadequate.
Consider:
If, like the original data sample, substrings can precede their superstings, line 7 should be excluded because both its $2 and $4 are substrings of line 9. Your code won't catch that.
Again, I could be mistaken. yifangt has not been strictly comprehensive in describing the problem.
I hope my nitpicking isn't getting on your last nerve.
Hi all,

How can I use uniq on a certain field or what else could I use? If I want to use uniq on the second field and the output would remove one of the lines with a 5.

ppix::regexp::token::literal
PPIx::Regexp::Token::Literal(3pm) User Contributed Perl Documentation PPIx::Regexp::Token::Literal(3pm)NAME
PPIx::Regexp::Token::Literal - Represent a literal character
SYNOPSIS
use PPIx::Regexp::Dumper;
PPIx::Regexp::Dumper->new( 'qr{foo}smx' )
->print();
INHERITANCE
"PPIx::Regexp::Token::Literal" is a PPIx::Regexp::Token.
"PPIx::Regexp::Token::Literal" has no descendants.
DESCRIPTION
This class represents a literal character, no matter how specified.
METHODS
This class provides the following public methods. Methods not documented here are private, and unsupported in the sense that the author
reserves the right to change or remove them without notice.
ordinal
print 'The ordinal of ', $token->content(),
' is ', $token->ordinal(), "
";
This method returns the ordinal of the literal if it can figure it out. It is analogous to the "ord" built-in.
It will not attempt to determine the ordinal of a unicode name ("N{...}") unless charnames has been loaded, and supports the vianame()
function. Instead, it will return "undef". Users of Perl 5.6.2 and older may be out of luck here.
Unicode code points (e.g. "N{U+abcd}") should work independently of charnames, and just return the value of "abcd".
It will never attempt to return the ordinal of an octet ("C{...}") because I don't understand the syntax.
SUPPORT
Support is by the author. Please file bug reports at <http://rt.cpan.org>, or in electronic mail to the author.
