How to enforce interactive keytool?

Shell Programming and Scripting
1

i am reading line by line from a file as below

while IFS= read -r var
do
...
...
...
done < "hello.txt"

I added the keytool command in the do while loop as below.

while IFS= read -r var
do
...
keytool -genkey -alias $fname -keyalg RSA -keystore $fname.jks -keysize 2048
...
done < "hello.txt"

But instead asking user to input the details the keytool is reading input from hello.txt and fails with the below error.

Can you help me fix this problem ?

while read LINE
do
        something-that-needs-terminal < /dev/tty
done < inputfile

I'm a little surprised keytool doesn't do this automatically, though. Usually things that read passwords absolutely insist on using the terminal. But if it's a bulk generation tool it makes sense.

Well, yes, you redirect stdin from "hello.txt", and keytool reads from stdin (c.f. man keytool )... Try opening "hello.txt" on another file descriptor.

Thank you @Corona .... Resolved.
