Shell Programming and Scripting

Hi,

When i am running the following shell scripting then i am getting the following output..

echo "sunita"
echo "now date is: `date`"
echo "enter command"
read command
read command
read command
read command
echo "command is: $command"
if [ "$command" = "" ]
then
echo "command is blank"
else
count=1
echo "count is $count"
((count=$count++1))
echo "it is enterred only $count times"
fi

Output is:
sunita
now date is: tuesday 20 40:9
count is 1
it is enterred only 2 times ---> here i need the 4 times(because i have entered 4 times in $command)

Can anybody tell me that how shell i get it??????
It is very urgent.....
can anybody help me???????

You read input four times. Each time, storing to the same variable name.
Then, you check on its status.
Print a 1 as count variable
add 1 to count
print out count again
Thus, the program is executing exactly as you wrote it.

You want to:
--store each variable to a distinct name
--loop through the variables when done (not a one-time if)

I got it but can you please tell me with the example...
