Thanks Don and all.

Sorry to come with addional requirement in same thread. I need to check for a triggering file say trigger_20170801(which is in YYYYMMDD) to trigger the subsequent scripts. Basically i would require to watch the file in particular directory before the start of the main_script in next day.

To be clear
main_Script.sh is scheduled everday 10:00PM
i need to check for the trigger file till 09:00 PM next day.

if i find the trigger file then proceed with script1.sh and so on
at the successful execution i will make the file as trigger_20170801_success else trigger_20170801_failed

At next day run i will check if success file present for that month i will just come out of the main script stating already completed for this month. If failed file present then exit stating failed for this month.

Using same approach of Don

Code:

echo "Checking for trigger file"
while true;
do
    if [ !-f $trigger_dir/trigg]
    do
   
    sleep 10
	else 

if [ -f $trigger_dir/trigg_success ]
then
echo "Previous run already completed"
exit 0;
fi 
[ -f status ] || date '+0 %c' > status

read job datestamp < status

if [ $job -eq 0 ]
then	if sh -x script1.sh > script1.log
	then	job=$((job + 1))
		date "+$job %c" > status
	else	echo "Failed due to some reason"
	mv $trigger_dir/trigg > $trigger_dir/trigg_failed
		exit 1
	fi
fi

if [ $job -eq 1 ]
then	if sh -x script2.sh > script2.log
	then	job=$((job + 1))
		date "+$job %c" > status
	else	echo "Failed due to some reason"
	mv $trigger_dir/trigg > $trigger_dir/failed
		exit 2
	fi
fi

if sh -x script3.sh > script3.log
then	job=0
	date "+$job %c" > status
	mv $trigger_dir/trigg > $trigger_dir/trigg_success
else	echo "Failed due to some reason"
mv $trigger_dir/trigg > $trigger_dir/trigg_failed
	exit 3
fi
fi
done

I need to validate for that month run trigger file and act. Also check for the trigger file till 09:00 PM next day

service

service(8)						      System Manager's Manual							service(8)

NAME

       service - run a System V init script

SYNOPSIS

       service SCRIPT COMMAND [OPTIONS]

       service --status-all

       service --help | -h | --version

DESCRIPTION

       service	runs a System V init script in as predictable an environment as possible, removing most environment variables and with the current
       working directory set to /.

       The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT.  The  supported  values  of  COMMAND  depend  on  the
       invoked	script.  service passes COMMAND and OPTIONS to the init script unmodified.  All scripts should support at least the start and stop
       commands.  As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start  com-
       mand.

       service --status-all runs all init scripts, in alphabetical order, with the status command.

EXIT CODES

       service calls the init script and returns the status returned by it.

FILES

       /etc/init.d
	      The directory containing System V init scripts.

ENVIRONMENT

       LANG, TERM
	      The only environment variables passed to the init scripts.

SEE ALSO

       /etc/init.d/skeleton,
       update-rc.d(8),
       init(8),
       invoke-rc.d(8).
