   esac
done

You miss the pipeline character between ls and while statements

Code:

nsec=1
while [[ "$(date +%H%M)" -lt 2340 ]]
do
   ls $DatafilesDir/[Uu][Pp][Ll][Oo][Aa][Dd].[0-9][0-9][0-9][0-9] 2>/dev/null | \
   while read filename
   do
      fileExtension=${fileName#*.}
      is_file_arrived "$fileName"
      if [ $arrived = 0 ]; then
         if [ ! -f "$TempDir/poll_$fileExtension.txt" ]; then
            nsec=1
            processFile $fileName $fileExtension
         else
            log_it "Store $fileExtension is already in process"
         fi
      fi
   done
   sleep $nsec
   case $nsec in
      1)   nsec=15;;
      15)  nsec=45;;
      45)  nsec=90;;
      90)  nsec=300;;
      300) nsec=600;;
      *) nsec=900;;
   esac
done

initscript

INITSCRIPT(5)						Linux System Administrator's Manual					     INITSCRIPT(5)

NAME

       initscript - script that executes inittab commands.

SYNOPSIS

       /bin/sh /etc/initscript id runlevels action process

DESCRIPTION

       When  the  shell  script /etc/initscript is present, init will use it to execute the commands from inittab.  This script can be used to set
       things like ulimit and umask default values for every process.

EXAMPLES

       This is a sample initscript, which might be installed on your system as /etc/initscript.sample.

	      #
	      # initscript   Executed by init(8) for every program it
	      # 	     wants to spawn like this:
	      #
	      # 	     /bin/sh /etc/initscript <id> <level> <action> <process>
	      #

		# Set umask to safe level, and enable core dumps.
		umask 022
		ulimit -c 2097151
		PATH=/bin:/sbin:/usr/bin:/usr/sbin
		export PATH

		# Increase the hard filedescriptor limit for all processes
		# to 8192.  The soft limit is still 1024, but any unpriviliged
		# process can increase it's soft limit up to the hardlimit
		# with "ulimit -Sn xxx" (needs a 2.2.13 or later Linux kernel).
		ulimit -Hn 8192

		# Execute the program.
		eval exec "$4"

FILES

       /etc/inittab, /etc/initscript.
