Some ideas

use autodie, 3 argument open, lexical file handles

use autodie;
open my($stuff), '<', 'in.txt' ; # with autodie, no need to "or die"
... <$stuff> ...
close $stuff; # with autodie, no need to "or die"

post a runnable program, not fragments, see How do I post a question effectively?
document said program (expected input, expected output, how the actual output differs from expected), so it makes sense to a stranger like me :)
for example, you say no error output information, but the line in large line number is defective, like below:
but then you don't explain the format, or how your output is defective

Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!

Titles consisting of a single word are discouraged, and in most cases are disallowed outright.

Read Where should I post X? if you're not absolutely sure you're posting in the right place.

Please read these before you post! —

Posts may use any of the Perl Monks Approved HTML tags:

a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr

You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)

	For:		Use:
	&		`&`
	<		`<`
	>		`>`
	[		`[`
	]		`]`
