Try the first (long) script to find where ksh doesn't accept the syntax because it works under bash (or try to replace the #!/bin/ksh by #!/bin/bash

The code does work...

Code:
for FILENAME in /home/voicem/ivr/arivra/*.tar
do
let AGE=(`date +%s` - `date -r $FILENAME +%s`)/86400
echo $AGE
done

The results are exactly what I expected...it is a list of the age of each file (in days)...

Code:
$ ./test
28
21
14

However, I still need help with getting the age (in days) to show up to the right of each file. I'd like to see this:
Code:
$ ls -l
total 9830796
-rw-r--r-- 1 voicem voicem 2011396608 Oct 21 03:06 file1.tar 28 
-rw-r--r-- 1 voicem voicem 2010897920 Oct 28 02:32 file2.tar 21
-rw-r--r-- 1 voicem voicem 2007906816 Nov 4 02:29 file3.tar 14

Code:
files=/home/voicem/ivr/arivra/*.tar
ls -l $files |
while read line
do
  read a b c d e f g h FILENAME <<EOF
$line
EOF
  age=$(( ( $(date +%s) - $(date -r "$FILENAME" +%s) ) / 86400 ))
  printf "%s %d\n" "$line" "$age"
done
