hi all
iam not able use read command in the while loop in the following program

while read line
do
echo $line
echo "enter name"
read name
echo "your have entered $name"
done < work.txt
THE READ COMMAND INSIDE THE WHILE LOOP IS NOT WORKING, IS ANY OTHER WAY TO SOLVE THIS PROBLEM

thanks to every one :confused:

Since read gets that file work.txt spooled in, it get's it's answers from it. Anyway maybe explain what you want to do - maybe there is an alternative way. I see no useful use :eek: of work.txt in this script.

Hope this helps:

TTY=`tty`

while read line
do
echo $line
echo "enter name"
read name < $TTY
echo "your have entered $name"
done < work.txt

Or just:
TTY=`/dev/tty`

just wanted to add that the reason it's not working is because
you are reading from stdin in 2 places:

while read....

and read...

that's what's causing the problem.

$ TTY=`/dev/tty`
bash: /dev/tty: Permission denied

I think you meant:

TTY='/dev/tty'

Or

TTY=`tty`
