It seems to me that you want the two most recent files. Have you considered:-
Code:
ls -1rt|tail -2|while read var2 # -1rt is number one (for one file name per line) rt (for reverse time order)
do
read var1
done
Of course, this relies on the files update timestamp being in the correct sequence. if you would prefer to work on the file name being the determining factor, then:-
Code:
ls -1 Daily_*|tail -2|while read var2
do
read var1
done
....or if there are a large number of files, you might be better with a find, such as:-
Code:
find . -name "Daily_*.txt"|sort|while read var2
do
read var1
done
The sort is required because the order of find will probably read in i-node sequence, which is not necessarilly the order you want.

struct::compare
Compare(3pm) User Contributed Perl Documentation Compare(3pm)NAME
Struct::Compare - Recursive diff for perl structures.
SYNOPSIS
use Struct::Compare;
my $is_different = compare($ref1, $ref2);
DESCRIPTION
Compares two values of any type and structure and returns true if they are the same. It does a deep comparison of the structures, so a hash
of a hash of a whatever will be compared correctly.
This is especially useful for writing unit tests for your modules!
PUBLIC FUNCTIONS
o $bool = compare($var1, $var2)
Recursively compares $var1 to $var2, returning false if either structure is different than the other at any point. If both are
undefined, it returns true as well, because that is considered equal.
BUGS /NEEDED ENHANCEMENTS
o blessed references
compare currently does not deal with blessed references. I need to look into how to deal with this.
