I have to filter out data from a file based on the value of first three characters of each record I have used the following logic
FIN=$LOC/TEST2.TXT
FEEDFILE=$LOC/TEST1.TXT
while read FDROW
do
FEEDROW=$FDROW;
DTYPE=`echo $FEEDROW |cut -c 1-3`
if [ $DTYPE -eq 300 ] ; then
echo $FEEDROW >> $FIN
fi
done < $FEEDFILE
However there is one problem thats occuring in this caseRecords are shrinking as while reading the file when the data (record) is getting stored in $FDROW variable blank spaces within record are being truncated and this is creating problems as the base file/output file, that I am using is a flat file and hence field positions are getting disturbed in the output file TEST2.txt, is there a way to prevent this or is there any other way this can be done?
