thanks Guys,

the requirement changed a little, we will read from file1, and use field1 and field2 find record in file2 and get filename and file content from file2.

I tried to write with while loop, it works. just wondering if the code can be improved.
I saw all answers use awk.

I know a little bit of awk. I will check the doc to fully understand the syntax, otherwise I will have problem if I just copy and paste.

Code:
 
 #!/bin/ksh
IFS=","
 error_cnt=0
while read zone feed date
do
echo $zone, $feed, $date
        exist_flag=0
        while read zone1 feed1 fname fct
                do
                        if [ $zone == $zone1 ] && [ $feed == $feed1 ]; then
                                echo "export ${fct}=${date}" > ${fname}
                                exist_flag=1
                                break
                        fi
                done<metapull.txt
        if [ exist_flag -eq 0 ]; then
                echo $zone, $feed " doesn't exisit in meta file" >> miss_records.txt
                error_cnt=1
        fi
done<sample.txt
 if [ error_cnt -ne 0 ]; then
        echo "Some feeds missing detail information, please check file " miss_records.txt
        exit 1
fi

rtc

rtc(1M) 						  System Administration Commands						   rtc(1M)

NAME

       rtc - provide all real-time clock and GMT-lag management

SYNOPSIS

       /usr/sbin/rtc [-c] [-z zone-name]

DESCRIPTION

       On x86 systems, the rtc command reconciles the difference in the way that time is established between UNIX and MS-DOS systems. UNIX systems
       utilize Greenwich Mean Time (GMT), while MS-DOS systems utilize local time.

       Without arguments, rtc displays the currently configured time zone string. The currently configured time zone string is based on  what  was
       last recorded by rtc-z zone-name.

       The  rtc  command  is  not normally run from a shell prompt; it is generally invoked by the system. Commands such as date(1) and rdate(1M),
       which are used to set the time on a system, invoke /usr/sbin/rtc -c to ensure that daylight savings time (DST) is corrected for properly.

OPTIONS

       -c	       This option checks for DST and makes corrections if necessary. It is normally run once a day by a cron job.

		       If there is no RTC time zone or /etc/rtc_config file, this option will do nothing.

       -z zone-name    This option, which is normally run by the system at software installation time, is used to specify the time zone  in  which
		       the  RTC is to be maintained. It updates the configuration file /etc/rtc_config with the name of the specified zone and the
		       current GMT lag for that zone. If there is an existing rtc_config file, this command will update it. If not,  this  command
		       will create it.

FILES

       /etc/rtc_config	       The data file used to record the time zone and GMT lag. This file is completely managed by /usr/sbin/rtc, and it is
			       read by the kernel.
