Shell Programming and Scripting

Hi all,

ok here is my problem, my program below is reading lines in from a file (one at a time) and printing them out. my problem is that i want it to only print out 3 lines at a time on the screen, but the "read value" command in my code isnt working. Whats wrong? & what can i do to get this working?

Thanks all for you replies in advance.

IFS=^
clear
counter=0
file=$1
cat $file |
while read line
do
counter=`expr $counter + 1`
set $line
echo -e "\t\t------------------------------------------------"
echo -e "\t\t| Name: $1 \r\t\t\t\t\t\t\t\t|"
echo -e "\t\t| Address : $2 \r\t\t\t\t\t\t\t\t|"
echo -e "\t\t| $3 \r\t\t\t\t\t\t\t\t|"
echo -e "\t\t| $4 \r\t\t\t\t\t\t\t\t|"
echo -e "\t\t| PhoneNumber: $5 \r\t\t\t\t\t\t\t\t|"
echo -e "\t\t| Fax Number: $6 \r\t\t\t\t\t\t\t\t|"
echo -e "\t\t| E-mail: $7 \r\t\t\t\t\t\t\t\t|"
echo -e "\t\t| Website: $8 \r\t\t\t\t\t\t\t\t|"
echo -e "\t\t| |"
echo -e "\t\t| o o |"
echo -e "\t\t------------------------------------------------"
echo " "

if [ $counter = 3 ]
then
echo "Hit Enter to continue..."
read value
fi

Code:

IFS=^
clear
counter=0
file=$1
cat $file |
while read line
do
        counter=`expr $counter + 1`
        set $line
        echo -e "\t\t------------------------------------------------"
        echo -e "\t\t|  Name: $1 \r\t\t\t\t\t\t\t\t|"
        echo -e "\t\t|  Address : $2 \r\t\t\t\t\t\t\t\t|"
        echo -e "\t\t|            $3 \r\t\t\t\t\t\t\t\t|"
        echo -e "\t\t|            $4 \r\t\t\t\t\t\t\t\t|"
        echo -e "\t\t|  PhoneNumber: $5 \r\t\t\t\t\t\t\t\t|"
        echo -e "\t\t|  Fax Number: $6 \r\t\t\t\t\t\t\t\t|"
        echo -e "\t\t|  E-mail: $7 \r\t\t\t\t\t\t\t\t|"
        echo -e "\t\t|  Website: $8 \r\t\t\t\t\t\t\t\t|"
        echo -e "\t\t|                                               |"
        echo -e "\t\t|                o              o               |"
        echo -e "\t\t------------------------------------------------"
        echo " "

        if [ $counter = 3 ]
        then
                echo "Hit Enter to continue..."
                read value < /dev/tty
                counter=0
        fi

done

Since read command used here indicates that its input is from a file,
a further read within a while loop will not work.

Hence when using a read within a while loop explicitly mention from where read should get the input
Within the while loop read command value is read from terminal /dev/tty
