Shell Programming and Scripting

Hi All,
Im trying to write a script to archive files based on the date the files were created.
For example, if a group of files were created on 23rd August,I would have 230806.tar. I have a problem,I want the script to read a separately created file(readarchive.txt) to look for the path to archive.It reads the days(after how many days to archive files) and the path.I am not able to figure out how to pass in the readarchive.txt.
Heres the script

Code:

#!/bin/ksh

BIN=/Gunner/users/Arsenal/tarfiles

age=$1
directory="$2"

[ "$directory" = "" ] && directory=.

cd "$directory" || exit 1

from=`$BIN/today -$age`

ls -rt | grep -v '.tar$' | $BIN/dttmfilter | awk '$1<="'$from'"{ print;};' | \
while read d t f
do
   [ -d $f ] && continue
   opt=u
   [ -w $d.tar ] || opt=c
   tar ${opt}f $d.tar $f && touch -r $f $d.tar && rm -f $f
done

Note:dttmfilter and today a c program!The program is working fine,it does exactly what I want it to do,but only when I manually copy the script to the folder I want to archive the files.Now I need to pass readarchive.txt which looks like this:

20 /gunner/chelsea (means archive all files in this folder after 20days) how do I include this in the program?

Thanks

Code:

while read d t f
do
   [ -d $f ] && continue
   opt=u
   [ -w $d.tar ] || opt=c
   tar ${opt}f $d.tar $f && touch -r $f $d.tar && rm -f $f
done <readarchive.txt

I guess you want to read from readarchive.txt file using this while loop ??
at the end of done add <filename so that it will read line by line from that file and assigned it to the variable d t f
