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

LEARN ABOUT PHP

session_name

SESSION_NAME(3) 							 1							   SESSION_NAME(3)

session_name - Get and/or set the current session name

SYNOPSIS

       string session_name ([string  $name])

DESCRIPTION

       session_name(3) returns the name of the current session. If $name is given, session_name(3) will update the session name and return the old
       session name.

	The session name is reset to the default value stored in session.name at request startup time. Thus, you need to call session_name(3)  for
       every request (and before session_start(3) or session_register(3) are called).

PARAMETERS

	      o $name
		- The session name references the name of the session, which is used in cookies and URLs (e.g.	PHPSESSID). It should contain only
		alphanumeric characters; it should be short and descriptive (i.e. for users with enabled cookie warnings). If $name is	specified,
		the name of the current session is changed to its value.

	      Warning

		      The  session name can't consist of digits only, at least one letter must be present. Otherwise a new session id is generated
		     every time.

RETURN VALUES

	Returns the name of the current session. If $name is given and function updates the session name, name of the old session is returned.

EXAMPLES

       Example #1

	      session_name(3) example

	      <?php

	      /* set the session name to WebsiteID */

	      $previous_name = session_name("WebsiteID");

	      echo "The previous session name was $previous_name<br />";
	      ?>

SEE ALSO

	The session.name configuration directive .
