Read file using while loop not reading last line

I have written a script to read the file line by line.
It is reading and printing the lines.
But it is coming out of loop before reading last line.
So I am not able to print last line.
How do I solve it.

Quote:
while read line
do

let line_count="line_count + 1"
echo "line count $line_count : $line"

done < abc.txt

IO::Lines(3)						User Contributed Perl Documentation					      IO::Lines(3)

NAME
IO::Lines - IO:: interface for reading/writing an array of lines SYNOPSIS
use IO::Lines; ### See IO::ScalarArray for details DESCRIPTION
This class implements objects which behave just like FileHandle (or IO::Handle) objects, except that you may use them to write to (or read from) an array of lines. They can be tiehandle'd as well. This is a subclass of IO::ScalarArray in which the underlying array has its data stored in a line-oriented-format: that is, every element ends in a " ", with the possible exception of the final element. This makes "getline()" much more efficient; if you plan to do line- oriented reading/printing, you want this class. The "print()" method will enforce this rule, so you can print arbitrary data to the line-array: it will break the data at newlines appropriately. See IO::ScalarArray for full usage and warnings.
