File processing line by line
Hi,

I am doing file processing line by line. while reading each line at a specified location I am searching for a particular character and then write that line to another file.

Problem is while writing to another file it was supressing the spaces, which I don't want to do.

Any help is appreciable.


the code I used is

processLine(){
line="$@" # get all args
type=`echo $line | cut -c37`
if [ $type = 'A' ] ; then
atlr=`expr $atlr + 1`
echo $line
echo $line >> trana
fi
}

example :
abc1234 XXX40 1100
it was writing to file as
abc1234 XXX40 1100

Thanks in advance

Code:
atlr=0
while  read record
do
    echo "$record" | cut -c37 | read char
    if [[ "$char" = "A" ]] ; then
         echo "$record"
         atlr=$((atlr + 1 ))
    fi
done < infile > outfile
echo "$atlr lines found"
