Learn to handle `SIGCHLD` signals in Bash for asynchronous monitoring of background processes. Utilize the `trap` command to set up real-time alerts on process completion, enabling efficient cleanup and updates within your scripts. This technique improves responsiveness and is ideal for managing multiple concurrent tasks.

This blog article examines using `SIGCHLD` for asynchronous child process monitoring in bash. It explains how `SIGCHLD` helps manage child processes by notifying the parent process about their status changes. Utilizing the `trap` command, the blog demonstrates setting handlers for `SIGCHLD`, enabling efficient clean-up and processing after a child process ends, thus enhancing script robustness in handling multiple child processes.
