While/ For loop not picking up commands

Question

I'm new to Korn shell scripting but learning as I go. I'm trying to run a WHILE loop with a nested FOR loop to read a CFG file and remove certain files that are older than a set number of days. The script runs fine without errors but it doesn't seem to be picking up the commands I have inside the loop. Below ill include the script, CFG file example and the output of the script with set -x included. Everything I've tried so far either fails or does not pick up the command. TIA!

CFG FILE;

FILE_PATH=/export/home/jaqst/training/testdir_1/ *.txt DAYS=7
FILE_PATH=/export/home/jaqst/training/testdir_1/ *.txt DAYS=14

Script;

 #!/bin/ksh
 set -x
 
 . ${HOME}/.profile
 #set up variables
 CFGFILE=/export/home/jaqst/training
 DATE=$(date +%s)
 #
 # Main processing starts here
 #
 echo `date +%d\ %b\ %H:%M` `basename $0` ${USER} "Job started"
 #
 #
 # CD CFG File location
 #
 cd ${CFGFILE}
 if [[ $? -ne 0 ]]
    then
    echo `date +%d\ %b\ %H:%M` `basename $0` ${USER} "failed to cd into ${CFGFILE}"
    exit 9
 fi
 #
 # Remove files that are older than specified age
 #
 while read FILE_PATH;
 do
    read DAYS
       for FILE in $FILE_PATH/*; do
          for TIME in $DAYS/*; do
             if [ -f $FILE ]; then
                if [ "$(find $FILE -mtime +$DAYS -print)" ]; then
                   rm -f $FILE
                   echo "Deleted $FILE"
                fi
             fi
       done
 done < hkeep_hera_cfg
 #
 if [[ $? -ne 0 ]]
    then
    echo `date +%d\ %b\ %H:%M` `basename $0` ${USER} "failed to remove file"
    exit 9
 fi
 #
 echo `date +%d\ %b\ %H:%M` `basename $0` ${USER} "Job Completed"
 #
 exit 0

Output;

12 Jul 11:44 hkeep_hera_draft jaqst Job started
+ cd /export/home/jaqst/training
+ [[ 0 -ne 0 ]]
+ 0< hkeep_hera_cfg
+ read FILE_PATH
+ read DAYS
+ 0< hkeep_hera_cfg
+ [ -f FILE_PATH=/export/home/jaqst/training/testdir_1 ]
+ [ -f FILE_PATH=/export/home/jaqst/training/testdir_1 ]
+ [ -f DAYS='7/*' ]
+ [ -f DAYS='7/*' ]
+ [[ 0 -ne 0 ]]
+ read FILE_PATH
+ date '+%d %b %H:%M'
+ basename ./hkeep_hera_draft
+ echo 12 Jul 11:44 hkeep_hera_draft jaqst 'Job Completed'
12 Jul 11:44 hkeep_hera_draft jaqst Job Completed
+ exit 0

From the output it also looks like it is only reading the first line in the CFG file.

I have tried a mixture of WHILE and FOR loop combinations and started to look into using the AWK command to see if this would allow the script to read the file easier.

I have also tried this method below but it errored out with the message - [52] [: argument expected

while read FILE_PATH; do 
   read DAYS
   for FILE in $FILE_PATH/*; do
   for TIME in $DAYS/*; do
   mod_time=$(stat -c %Y $FILE)
   current_time=$(date +%s)
   age=$(( (current_time - mod_time) / (24 * 60) ))
 if [ $age -gt $DAYS ]
    then 
    rm $FILE
 fi
 if [[ $? -ne 0 ]] 
    then
    echo `date +%d\ %b\ %H:%M` `basename $0` ${USER} "failed to remove file"
    exit 9
 fi
 done < hkeep_hera_cfg

Answer 1

This is what I eventually ended up using to over come the issue of the script not reading the CFG correctly.

CFG EXAMPLE

TESTDIR1,/u01/home/dir1/dir2/test1,.txt,7

TESTDIR2,/u01/home/dir1/dir2/test2,.csv,7

SCRIPT

while IFS=, read ID FILE_PATH EXT DAYS ;
do
if [[ -z "${ID}" || -z "${FILE_PATH}" || -z "${EXT}" || -z "${DAYS}" ]];
then
  echo `date +%d\ %b\ %H:%M` `basename $0` ${USER} "Failed to set up, please check config file." >> ${ERRLOG}
  mail_err
  exit 9
fi
#
cd ${FILE_PATH}
if [[ $? -ne 0 ]]
then
   echo `date +%d\ %b\ %H:%M` `basename $0` ${USER} "failed to cd into ${FILE_PATH}" >> ${ERRLOG}
   mail_err
   exit 9
fi
#
find . \( -name ${EXT} \) -mtime +${DAYS} -exec rm -r {} 2>/dev/null \;
if [[ $? -ne 0 ]]
then
  echo `date +%d\ %b\ %H:%M` `basename $0` ${USER} "failed to remove ${EXT} from ${FILE_PATH}" >> ${ERRLOG}
  mail_err
  exit 9
fi 
done < ${CFGFILE}
