Loop counter resets by itself
Hi!

Can anyone explain this? The counter CDR_count should go on forever, but it suddenly resets at every step of the FOR loop (I know this because $_file has exactly 378 records). However, the counter reset is OUTSIDE the FOR loop. What's going on??

Code:
#!/bin/bash

if [ "$1" = "" ] || [ "$2" = "" ]; then
   echo
   echo "USAGE: ./CCN_CDR_parser.sh <CCN CDR files - path & wildcard allowed> <MSISDN>"
   echo
   exit
fi

echo
echo "Searching CDRs for MSISDN $2 in:"
echo "$1"
echo

file_count=0
file_total=`ls -1 $1 | wc -l | tr -d " "`
CDR_count=0
CDR_match=0
echo > CDR.tmp

for _file in `ls -1 $1`
do
  echo -ne "Files processed: $file_count / $file_total       CDRs match : $CDR_match / $CDR_count"\\r
  file_count=`expr $file_count + 1`

     cat $_file | while read _line
     do

             if [ "$_line" = "CDRCCN.ChargingDataOutputRecord.onlineCreditControlRecord" ]; then

                CDR_count=`expr $CDR_count + 1`
                echo "Files processed: $file_count / $file_total       CDRs match : $CDR_match / $CDR_count"

                if [ "`grep "servedAccount : '$2'" CDR.tmp`" != "" ]; then
                   CDR_match=`expr $CDR_match + 1`
                   mv CDR.tmp CDR$CDR_match.txt
                   echo -ne "Files processed: $file_count / $file_total       CDRs match : $CDR_match / $CDR_count"\\r
                fi

                CDR_start="true"
             else
                CDR_start="false"
             fi


             if [ "$CDR_start" = "true" ]; then
                echo $_line > CDR.tmp
             else
                echo $_line >> CDR.tmp
             fi

      done
done

echo
echo

Code:
Files processed: 23 / 1192       CDRs match : 0 / 373
Files processed: 23 / 1192       CDRs match : 0 / 374
Files processed: 23 / 1192       CDRs match : 0 / 375
Files processed: 23 / 1192       CDRs match : 0 / 376
Files processed: 23 / 1192       CDRs match : 0 / 377
Files processed: 23 / 1192       CDRs match : 0 / 378
Files processed: 24 / 1192       CDRs match : 0 / 1
Files processed: 24 / 1192       CDRs match : 0 / 2
Files processed: 24 / 1192       CDRs match : 0 / 3
Files processed: 24 / 1192       CDRs match : 0 / 4
