Bash script scenarios to handle SIGINT correctly when running multiple background jobs
I'm working on a project and hit a roadblock. I'm deploying to production and I'm having trouble with I'm converting an old project and I recently switched to I'm confused about I'm working with an scenario where my Bash script does not behave as expected when I try to interrupt it with Ctrl+C while it has multiple background jobs running..... The script is supposed to gracefully terminate all background processes, but instead, it seems to just exit without cleaning up. Here's a simplified version of my script: ```bash #!/bin/bash # Function to clean up background jobs cleanup() { echo "Cleaning up..." kill 0 # This sends SIGTERM to all jobs in the current process group } # Trap SIGINT to call cleanup rap cleanup SIGINT # Start multiple background jobs for i in {1..5}; do (sleep 10; echo "Job $i done") & done wait # Wait for all background jobs to finish ``` When I run this script and press Ctrl+C, I would expect it to call the `cleanup()` function and terminate all background jobs. However, what I see in the terminal is just that the script exits without any cleanup message. I've tried different variations of the `trap` command and even using `trap 'cleanup; exit' SIGINT`, but the behavior remains the same. I also checked my terminal settings to ensure that Ctrl+C is indeed sending SIGINT, and it is working fine in other circumstances. I'm using Bash version 5.1 on Ubuntu 20.04. Could anyone point out what I'm missing or how to ensure that my cleanup function is executed upon receiving a SIGINT signal? Any ideas what could be causing this?
