Shell Programming and Scripting

I have a line in my script which reads as

Code:

exec >> $LOG 2>&1

However I am required to get input from the user somewhere in between as follows.

Code:

read var?"Enter a value:" < /dev/tty

The execution of the script puts the prompt of the read command to the log file rather than the console, since I am redirecting the output in the begining.

I would like for the read prompt to appear in the console/display as well as go to the $LOG file.
After the user input is read from the console, the subsequent stdout and std err should go to the $LOG files. How can I achieve this? Please advise. Thanks

read var?"Enter a value:" < /dev/tty > /dev/tty 2>&1

Perderabo,

The above snippet has the same effect as before when I did not have the additional

Code:

> /dev/tty 2>&1

The prompt only appears in the log file and I do not see it on the screen.
Thanks

Perderabo,

following your guideline I had changed the code to the following and it seems to work.

Code:

exec >> ./logfile 2>&1
while read line
do
        echo $line
        read var?"Enter a value:" < /dev/tty > `tty` 2>&1
        echo $var
done < testfile

Thanks for your input.

Just retried it. It continues to work for me. You must have a typo or something.
