scripting headache... loops & variables
Surely there's an easier way to do this, lets see if anyone knows! I am new to scripting so go easy on me!

I have the following script and at the moment it doesn't work and I believe the problem is that I am using a while loop within a while loop. When I run the script using sh -x I can see that it is grepping each $DAACFILE but gets no result, so I think $IP has no value set when running this part of the script, which results in the file, gettrack, containg no data... so the result is that MSISDN.out is empty. Any help much appreciated.

LOGDIR=/usr/local/tibco/adapters/DAAC/bin/archive/
TEMPDIR=/usr/local/tibco/adapters/DAAC/bin/archive/temp/

rm $TEMPDIR/getMSISDN.sh
rm $TEMPDIR/MSISDN.out
touch $TEMPDIR/getMSISDN.sh
chmod +x $TEMPDIR/getMSISDN.sh

echo "Enter the month (e.g Jan) you wish to extract MSISDN's for : "
read MONTH
echo "Enter the number of the day (1-31) you wish to extract MSISDN's for : "
read DAY

DAYLOG=$TEMPDIR"$MONTH$DAY"

#CREATES MSISDN.OUT BY COPYING RELEVANT DAYS LOG FILES TO TEMP LOG DIRECTORY, EXTRACTS IP FROM extract??.EST.txt AND GREPS DAAC LOGS FOR MSISDN BASED ON IP ADDRESS AND TRACKINGID.

echo "DMS transactions by MSISDN" > $TEMPDIR/MSISDN.out
ls $DAYLOG > $TEMPDIR/list_files
# exec < $TEMPDIR/list_files
# while read DAACFILE
cat $TEMPDIR/list_files | while read DAACFILE
do
{
#awk '{print $7}' $TEMPDIR/extract$DAY.EST.txt|while read IP
awk '{print $7}' $TEMPDIR/extract22.EST.txt|while read IP
do
# grep $IP $DAYLOG$DAACFILE | grep tracking > $TEMPDIR/gettrack;
grep $IP $DAYLOG$DAACFILE | grep tracking >> $TEMPDIR/gettrack;
awk '{print$15}' $TEMPDIR/gettrack| sed 's/tracking=/grep "/' | sed "s/zzw\#/\" $DAACFILE \| grep \"MSISDN :\"/" >> $TEMPDIR/getMSISDN.sh;
$TEMPDIR/getMSISDN.sh | awk '{print $1, $2, $3, $4, $5, $6, $12, $13}' >> $TEMPDIR/MSISDN.out
done
}
# rmdir $DAYLOG
done

rredtool

RREDTOOL(1)							     REPREPRO							       RREDTOOL(1)

NAME

       rredtool - merge or apply a very restricted subset of ed patches

SYNOPSIS

       rredtool --help

       rredtool [ options ] --merge patches...

       rredtool [ options ] --patch file-to-patch patches...

       rredtool directory newfile oldfile mode

DESCRIPTION

       rredtool  is  a	tool to handle a subset of ed patches in a safe way.  It is especially targeted at ed patches as used in Packages.diff and
       Sources.diff.  Is also has a mode supposed to be called from reprepro as Index Hook to generate and update a Packages.diff/Index file.

MODI

       One of the following has to be given, so that rredtool know that to do.

       --version
	      Print the version of this tool (or rather the version of reprepro which it is coming with).

       --help Print a short overview of the modi.

       --patch
	      The first argument of rredtool is the file to patch, the other arguments are ed patches to apply on this one.

       --merge
	      The arguments are treated as ed patches, which are merged into a single one.

       --reprepro-hook (or no other mode flag)
	      Act as reprepro index hook to manage a Packages.diff/index file.	That means it expects to get exactly 4 arguments  and  writes  the
	      names of files to place into filedescriptor 3.

	      If neither --patch nor --merge is given, this mode is used, so you can just put

	       DebIndices: Packages Release . .gz /usr/bin/rredtool

	      into  reprepro's	conf/distributions  file  to  have a Packages.diff directory generated.  (Note that you have to generate an uncom-
	      pressed file (the single dot).  You will need to have patch, gzip and gunzip available in your path.)

OPTIONS

       --debug
	      Print intermediate results or other details that might be interesting when trying to track down bugs in rredtool but not	intresting
	      otherwise.

       --max-patch-count=count
	      When generating a Packages.diff/Index file, put at most count patches in it (not counting possible apt workaround patches).

       -o|--output
	      Not yet implemented.

ENVIRONMENT

       TMPDIR, TEMPDIR
	      temporary files are created in $TEMPDIR if set, otherwise in $TMPDIR if set, otherwise in /tmp/.
