Updating a field in a File without creating temp file's

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;

cscope-indexer

cscope-indexer(1)					      General Commands Manual						 cscope-indexer(1)

NAME

       cscope-indexer - Script to index files for cscope

SYNOPSIS

       cscope-indexer [-v] [-f database_file] [-i list_file] [-l] [-r]

DESCRIPTION

       This  script  generates	a list of files to index (cscope.out), which is then (optionally) used to generate a cscope database.  You can use
       this script to just build a list of files, or it can be used to build a list and database.  This script is not used to just build  a  data-
       base (skipping the list of files step), as this can be simply done by just calling "cscope -b".

       Normally,  cscope will do its own indexing, but this script can be used to force indexing.  This is useful if you need to recurse into sub-
       directories, or have many files to index (you can run this script from a cron job, during the night).  It is especially	useful	for  large
       projects,  which  can  contstantly  have source files added and deleted; by using this script, the changing sources files are automatically
       handled.

       Currently, any paths containing "/CVS/" or "/RCS/" are stripped out (ignored).

OPTIONS

       -f database_file
	      Specifies the cscope database file (default: cscope.out).

       -i list_file
	      Specifies the name of the file into which the list of files to index is placed (default: cscope.files).

       -l     Suppress the generation/updating of the cscope database file.  Only a list of files is generated.

       -r     Recurse into subdirectories to locate files to index.  Without this option, only the current directory is searched.

       -v     Be verbose.  Output simple progress messages.
