Hammer & Screwdriver Unable to set Global variable outside while loop
Below is my code:
Code:
 
count=0
if 
...
...
else
...
find * -prune -type d | sort -r -n |  while read d; do
count=1
 if [ "$count" == "1" ]; then
 echo "Count1:$count"
 ...
 ...
 break 2;
 fi
...
done 
...
fi
echo "Count2:$count"
if [ "$count" != "1" ]; then
echo "Problem"
fi

Output:
Count1:1
Count2:0
Problem

I did not expect "Problem" to be printed as i was expecting Count2:1.
I tried putting "( while read d; do" but i am not sure where should i close ")" to get it working.
Where am i going wrong and how should i resolve this.

tping

TPING(1)							   LAM COMMANDS 							  TPING(1)

NAME

       tping - Send echo messages to LAM nodes.

SYNOPSIS

       tping [-hv] [-c count] [-d delay] [-l length] nodes

OPTIONS

       -h	     Print the command help menu.

       -v	     Turn OFF verbose mode.

       -c count      Send count messages.

       -d delay      Delay delay seconds between each message.

       -l length     Each message is length bytes long.

DESCRIPTION

       The  tping  command  sends  messages  to,  and  collects replies from, a list of nodes, via the LAM echo server.  It is similar to the UNIX
       ping(8) command, and is used as a quick diagnosis of the LAM network.

       Unless options are specified, tping sends a 1 byte message an infinite number of times, displaying the roundtrip time of each message as it
       completes,  with  a delay of 1 second between roundtrips.  After the loop is broken (with keyboard interrupt, eg: ^C), tping prints statis-
       tics about all roundtrip messages.

EXAMPLES

       tping h
	   Echo messages to the local node.

       tping -v n7 -l 1000 -c 10
	   Echo 1000 byte messages to node 7.  Stay silent while working.  Stop after 10 roundtrips and report statistics.

BUGS

       There is no built-in timeout and tping will wait forever to receive an echo.  If no echo is received, due to a dead  link  or  node,  tping
       hangs.	Stop  the  process  with  a  keyboard suspend signal (eg: ^Z) and terminate LAM with lamhalt(1) or lamwipe(1) (although the use of
       lamwipe(1) is deprecated).
