Dining philosophers

Hi.
I`m writng script solving problem of dining philosophers but it does not work.
PHILOSOPHER SRIPT:

Code:

#!/bin/bash

./start.conf

cd stol
a=$1
#echo a$a
#echo ilosc$ilosc
#echo dziel$(($[a+1]%$ilosc))

if [ $a -eq $ilosc ] ; then 
   #next=$[$[a+1]%$ilosc]
   next=1
else
   next=$[a+1]
fi

#echo next $next
#echo $'\r'

zjedzonych=0
while  [ $zjedzonych -lt $jedz ] ; do

if [ $(($a%2)) -eq 1 ] ; then
   lockfile -1 -r 1 widelec$1

   if [ $? == 0 ] ; then
   echo $'\r'`date` - Filozof $a  podni�sł widelec $a

   	lockfile -1 widelec$next
   	echo `date` - Filozof $a podni�sł widelec $next

   	echo `date` - Filozof $a ucztuje
   	sleep $sleep

   	rm -f widelec$next
   	echo `date` - Filozof $a odłożył widelec $next

   	rm -f widelec$1
   	echo `date` - Filozof $a odłożył widelec $a
   	((zjedzonych++))
   else
        echo `date` - Filozof $a rozmyśla
        sleep $rozm
   fi

fi

done

START SCRIPT:

Code:

#!/bin/bash

./start.conf
mkdir stol

#x=1
while [ $x -le $ilosc ]; 
do

./filozof.sh $x &

#echo $ilosc
#echo $x

((x++))

done;

in the directory are three files. File "start.conf" contains the variables.
Please of little help !

To avoid deadlock, I used a possible solution. The odd numbered philosophers grab the right and then the left while even numbered philosophers grap the chopsticks in the reverse order. Implement this solution using pthread mutual exclusion lock. Please look at my code, although it works,but the...

NAME

       XmScrollVisible -- A ScrolledWindow function that makes an invisible
	descendant of a ScrolledWindow work area visible

SYNOPSIS

       #include <Xm/ScrolledW.h>
       void XmScrollVisible(
       Widget scrollw_widget,
       Widget widget,
       Dimension left_right_margin,
       Dimension top_bottom_margin);

DESCRIPTION

       XmScrollVisible makes an obscured or partially obscured widget or gadget descendant of a ScrolledWindow work area visible. The function re-
       positions the work area and sets the specified margins between the widget and the nearest viewport boundary. The widget's location relative
       to  the	viewport determines whether one or both of the margins must be adjusted. This function requires that the XmNscrollingPolicy of the
       ScrolledWindow widget be set to XmAUTOMATIC.

       scrollw_widget
		 Specifies the ID of the ScrolledWindow widget whose work area window contains an obscured descendant.

       widget	 Specifies the ID of the widget to be made visible.

       left_right_margin
		 Specifies the margin to establish between the left or right edge of the widget and the associated edge  of  the  viewport.   This
		 margin is established only if the widget must be moved horizontally to make it visible.

       top_bottom_margin
		 Specifies  the  margin  to  establish between the top or bottom edge of the widget and the associated edge of the viewport.  This
		 margin is established only if the widget must be moved vertically to make it visible.
