What is the most optimal way to do an infinite loop in bash?

  • 772

I get something like:

# Quiero que se ejecute un daemon hasta que se pulse control + c 
trap 'handle_exit 0' SIGINT

# El ciclo solo es para esperar que pulsen ctrl + c
while true
do
    sleep 1000000
done

Now, I want to know if there is a cleaner way to do that loop.

bash

    Just make it run forever by running a non-action:

    trap 'handle_exit 0' SIGINT

# El ciclo solo es para esperar que pulsen ctrl + c
while true
do
    :  # <--- esto no hace nada, es como un "pass" en Python
done
