Let's follow the logic here.

Code:

cnt=0
while [ $cnt -lt 600 ]
 do

    while [ $cnt -lt 300 ]
     do
      echo .
      # Instead of opening pinglog$$.txt n/15 times, redirect the
      # while loop itself, so you only open it once.
      ping -c 3 not_connected_IP#>>/tmp/pinglog$$.txt
      sleep 13
      ((cnt=cnt+15))
      # Jumps back up to the top of the loop if cnt is less than 300.
     done >> /tmp/pinglog$$.txt

    # to reach here, the while loop must have ended.  Therefore, 
    # cnt is already >= 300.  So this next while loop never happens.
    while [ $cnt -lt 300 ]
     do
      echo -n "Minutes since start = " > divres
      echo "scale=2; $cnt/60" | bc >> divres

#      this is a Useless Use of Cat.  http://partmaps.org/era/unix/award.html
#      grep doesn't need cat's help.
#
#      You should also use grep -q so grep doesn't try print matching lines.
#      Also:  Are you trying to match a literal dot?  dots mean 'any character'
#      grep.  Escape it with a backslash to make it match only the dot char.
#      if cat divres | grep .00
       if grep -q "\.00" < divres
       then
        echo
        cat divres
      fi
     done

     # Loops back to the beginning of the first while loop whenever
     # cnt is less than 600.
     # But cnt will never be greater than 300 because your inner
     # while loops stop doing anything past 300.
     # so this becomes an infinite loop!
 done
rm -r /tmp/pinglog$$.txt

I don't know how to simplify or fix a lot of this since I don't know what you were actually trying to do with it either.

NAME

       gnotime - GnoTime - a time tracker

SYNOPSIS

       gnotime [--display displayname] [--geometry geometry]

DESCRIPTION

       GnoTime is a simple combination of a stopwatch, a to-do-list organizer and time-keeping/billing system.

       In its simplest mode of operation, as a stopwatch, it simply counts the number of elapsed seconds while the timer is running.  Unlike ordi-
       nary stopwatches, it will keep a log of each time that the timer was started and stopped.  The log, or 'journal',  can  be  annotated  with
       comments, allowing a diary of events to be kept.

       GnoTime functions as a billing system by allowing you to assign a value to an hour's worth of time.  You can specify overtime, double-over-
       time rates and fixed flat-fees.	Individual chunks of time as 'billable', 'not-billable', 'no-charge', 'hold', and so on.

       GnoTime can also be used as a simple to-do list tracker.  You can assign an urgency as well as an importance to a given project, assign	an
       estimated  start  and end date, specify a sizing and a percent-complete value.  Clicking on column headings will sort the list in the order
       of that column.

       Custom reports can be created using standard HTML enhanced with embedded Scheme (a LISP -like programming language).

OPTIONS

       --display
	      specifies the X server that gnotime should connect to. Refer to the X(1x) manual page for more info.

       --geometry
	      specifies the geometry of the main window. The syntax [WIDTHxHEIGHT][(+|-)X(+|-)Y] is just like the X toolkit option geometry.   See
	      X(1x) for more info.

OTHER TYPES OF DOCUMENTATION

       You  can  find  more  information about GnoTime and its functions in the Gnome help system.  Just select Contents from the Help menu to get
       there.
