Since I am going to run the all the jobs parallely and there is high possiblity of updating the status and END TIME parallely in a file.

It has to update only one record in file without any temporary file to miss the latest updation.

It will be grateful if you could help me out to get sort out my requirement?

Thanks,

what have you tried till now??

Hi vidyadhar85,

I tried with below script, but the problem when I schedule this script multple times to run at a same time to update different record in a file it is not working properly,

input_path='/isscrmetl/data001/script test/file_upd'
list_file=$1
sess_name=$2
if [ ! -f "$input_path"/"$list_file" ]
then
echo "List file not found"
else

IFS=" "
touch "$input_path"/$2_temp_file
cat "$input_path"/"$list_file" | while read session_name load_type freq end_time prev_stat
do

if [ "$session_name" = "$sess_name" ]
then
load_type='INCREMENTAL'
freq='DAILY'
#end_time=`date +%m%d%Y` date +/%m%d%y.%H%M%S'.
#end_time=`date +%d-%h-%Y %t`
end_time=`date`
prev_stat='SUCCEEDED'
fi
echo "$session_name $load_type $freq $end_time $prev_stat"
echo "$session_name $load_type $freq $end_time $prev_stat" >>"$input_path"/$2_temp_file
done
#echo "Temp File"
#cat "$input_path"/$2_temp_file
mv "$input_path"/$2_temp_file "$input_path"/"$list_file"

#rm -f "$input_path"/$1_temp_file
fi

exit 0;

Pls. assist me to get this done.

Thanks,
