bash-3.00$ nawk -F"," '{ for (i=1;i<=NF;i++) {if(i==NF) {printf("%s\n",$NF)} else printf ("%s",$i)}}' /tmp/myfile

bash-3.00$ cat /tmp/myfile

read each word (seperated by comma) and just print it. If it is the last word, then print new line character ("\n")

Hey thanks, but both are not working
Below is the code.
In the code I am asking the user to enter the Location Code and Account number and status, then I am using Loaction and Account Number to match into a inputFile.txt and then writing the data to an output file. Also I have to write 400, date and status at the end of the line.

echo "Input Location Code"
read locationCode

echo "Input the Account number"
read accountNumber

echo "Input the Status"
read status

chmod 777 outFile.txt
chmod 777 outputFile.txt
egrep -i "$locationCode" inputFile.txt > tempFile.txt
grep -i "$accountNumber" tempFile.txt > outFile.txt

rm tempFile.txt

echo "400" >> outFile.txt
date "+%y/%m/%d" >> outFile.txt
echo $status >> outFile.txt

awk 'ORS=NR%1?RS:","' RS="\n" outFile.txt >> outputFile.txt

sed 's/,//g' outputFile.txt

cat outputFile.txt >> outputFilefinal.txt

echo "Processes Completed successfully"

Kindly look at the code and tell me where is the error.

Thank You very very much. It worked. Smilie Smilie

I just wanted to ask one thing more.
If suppose I wanted to read the file until I encounter a comma, then write that data into another file. How will I do that?
