Problem in while loop
Code:
date=$1

function convert_date
{
        cube_date=$1
        v_length=`echo $cube_date | awk '{print length}'`
        if [[ $v_length -ne 8 ]];then
                echo " Wrongly entered parameter , please enter date format as YYYYMMDD"
                exit 1
        fi
        YYYY=$(expr substr "$cube_date" 1 4 )
        MM=$(expr substr "$cube_date" 5 2)
        DD=$(expr substr "$cube_date" 7 2 )
        cal $DD $MM $YYYY >/dev/null 2>&1
        if [[ $? -ne 0 ]];then
                echo "Invalid date entry."
                exit 1
        fi

        case $2 in
        "eu" ) v_date=$YYYY$MM$DD ;;
        "us" ) v_date=$MM$DD$YYYY ;;
        *)      echo "Not valid date format "
                exit 1;;
        esac
}

while read system maskleft maskright folder_prd floder_uat datetype Region
do
        if [[ ${env} -eq "PRD" ]]; then
                case "${datetype}" in
                "eu" ) v_date=`convert_date ${date} ${datetype}`;;
                "us" ) v_date=`convert_date ${date} ${datetype}`;;
                *)      echo "invalid date format for ${system}/${maskleft}/${maskright}/$env"
                        exit 1;;
                esac
                date=$v_date
                filename=${maskleft}${v_date}${maskright}

i think it is due to first 4 lines in the config file...
try after removing those lines

I need to keep those #(s) in my reading file.
before reading the line I can remove thiose #(s) and store in tmp file and then read tmp file. But this way I'm taking longer way to extract the records.and in real case the file can be as big as possible with #(s) so any other way reading this records , so that it will be quicker?
