Bash script hangs while waiting for user input after executing a background process
I'm experiencing an scenario with a Bash script where it hangs after executing a background process, specifically when I wait for user input. My script is designed to run a command in the background and then prompt the user for input. However, it seems to get exploring after the background process starts and doesn't reach the input prompt. Here’s a simplified version of my script: ```bash #!/bin/bash # Start a long-running background process long_running_process() { sleep 10 echo "Process finished." } long_running_process & # Prompt for user input read -p "Please enter your name: " name echo "Hello, $name!" ``` When I run this script, it appears to hang indefinitely after starting the `long_running_process`. I can see the sleep command is executing in the background, but the script does not reach the `read` prompt until I send an interrupt (Ctrl+C). I've tried using `wait` to synchronize the background process, but it seems unnecessary since I want the user input to be available while that process runs. Is there something wrong with how I'm handling the background process, or is there a better approach to achieve this? I’m running this on Bash version 5.0.17 on Ubuntu 20.04. I've also tested it in a non-interactive shell, and it behaves the same way. Any insights on why this might be happening would be appreciated. I'm working with Bash in a Docker container on Debian. Is this even possible?
