Bash script not terminating background processes on exit
I just started working with I'm wondering if anyone has experience with I've searched everywhere and can't find a clear answer... I'm sure I'm missing something obvious here, but I'm working with an scenario with a Bash script where I spawn several background processes, but they continue running even after the script has terminated. I expected that using `trap` to handle the `EXIT` signal would clean them up, but it doesn't seem to be working as intended. Here’s a simplified version of my script: ```bash #!/bin/bash # Function to kill background processes cleanup() { echo "Cleaning up..." kill 0 # Kills all background jobs } trap cleanup EXIT # Start a long-running background process (sleep 60 &) # Another long-running process (sleep 120 &) # Simulating some work echo "Main script is doing work..." sleep 10 echo "Main script finished. Exiting..." ``` When I run this script, I see the `Cleaning up...` message, but the background processes are still running after the main script exits. I’ve tried replacing `kill 0` with `kill $(jobs -p)` to specifically target the background jobs, but that doesn't change the outcome. I've also checked the `set -m` option, which is supposed to enable job control in the shell, but it was already set by default. I'm running this in a standard Ubuntu 22.04 environment with Bash version 5.1. I would appreciate any insights on why the background jobs are not terminating as expected and how to fix this scenario without resorting to process monitoring or manual cleanup outside of the script. Any help would be great! For context: I'm using Bash on Ubuntu. My development environment is Linux. Any ideas what could be causing this? I'm coming from a different tech stack and learning Bash. For context: I'm using Bash on Ubuntu 20.04. Am I approaching this the right way?
