Help parse comma separated list
I have a list of files with the same name, but they have a different date stamp in the name. I can find the first file, but I need to find the second file. I am using this information to create a variable I use later. Here is a example of how I find the first file.
"ls -mr /HOME/Daily_????????.txt | cut -d "," -f1 | head -1"
files are Daily_20100101.txt, Daily_20100102.txt, Daily_20100103.txt, etc.
this list get converted to Daily_20100103.txt,Daily_20100102.txt,Daily_2010101.txt
The variable1 gets set to "/HOME/Daily_20100103.txt"
I can grab the most current day, but I also need the information for the prior day and I can not seem to grab the second file in the list.
I would like variable2 to be "/HOME/Daily_20100102.txt"
Thanks in advance for your assistance.

ATR_ANALYSIS(1p) User Commands ATR_ANALYSIS(1p)
NAME
ATR_analysis - analyse a smart card ATR
SYNOPSIS
ATR_analysis [ATRstring]
DESCRIPTION
ATR_analysis is used to parse the ATR (Answer To Reset) sent by a smart card.
The command also tries to find the card model using an ATR database stored in a text file smartcard_list.txt.
The smartcard_list.txt file is searched in ./, /usr/local/pcsc/ and /usr/share/pcsc/ directories.
Exemple:
$ ATR_analysis '3B A7 00 40 18 80 65 A2 08 01 01 52'
ATR: 3B A7 00 40 18 80 65 A2 08 01 01 52
+ TS = 3B --> Direct Convention
+ T0 = A7, Y(1): 1010, K: 7 (historical bytes)
TB(1) = 00 --> Programming Param P: 0, I: 0
TD(1) = 40 --> Y(i+1) = 0100, Protocol T = 0
-----
TC(2) = 18 --> Work waiting time: 960 x 24 x (Fi/F)
+ Historical bytes: 80 65 A2 08 01 01 52
Possibly identified card:
3B A7 00 40 18 80 65 A2 08 01 01 52
