Hi,

below is the code i am using

Code:
#!/usr/bin/bash

while read each_line
do
var_tcode=`echo $each_line | awk -F',' '{print $1}'`

done < WPA_20131120_APP0000108.csv

echo "Value:: "$var_tcode

i have a file "WPA_20131120_APP0000108.csv" having below data
Code:
CE2DD,00000000108,00000000108,,20.11.2013,2.38.00.00.100010,20.00,MVR,Web Payment

when i run the above script it does not print any thing but when i open the same .csv file in vi editor and exit with :wq option and i run the script it prints CE2DD

Is there some problem in .csv file format or permission??
