Using GNUparallelinside a Bashforloop provides an efficient way to handle tasks that require both sequential and parallel processing. Here’s a self-explanatory example where aforloop goes through a series of iterations, and within each iteration, GNUparallelspeeds up a job calledprocess_task: ...
If you want to create an infinite while loop instead, then you can create it as follows: while [ true ]; do [COMMANDS] done Awesome! This brings us to the end of this tutorial in the Bash Beginner Series. I hope you have enjoyed making looping around in bash!
