Question
You're writing a Bash script that should repeatedly prompt the user for input until they enter "quit" to exit. Which code snippet correctly implements this behavior using a while loop?1.0 Markswhile [ "input" != "quit" ]; doread -p "Enter a value (type 'quit' to exit): " inputdonewhile [ "input" == "quit" ]; thenbreakfidonewhile true; doread -p "Enter a value (type 'quit' to exit): " inputif [ "$input" == "quit" ]; thenbreakfidone
Solution
The correct code snippet that implements this behavior using a while loop is:
while true; do
read -p "Enter a value (type 'quit' to exit): " input
if [ "$input" == "quit" ]; then
break
fi
done
This script will continuously prompt the user to enter a value until they type 'quit'. The 'true' in the while loop condition makes the loop run indefinitely until 'break' is encountered. When the user types 'quit', the if condition becomes true and 'break' is executed, which terminates the loop.

You're developing a Bash script that reads lines from a text file. If a line contains the word "error," the script should display an error message and continue reading the next line. If a line contains the word "success," it should display a success message and break out of the loop. For all other lines, it should display a generic message.
