child processes

Welcome to another deep dive into the Linux operating system’s bash capabilities, where we focus today on handling the SIGCHLD signal to monitor child processes asynchronously. By understanding and using SIGCHLD, you can enhance your scripts to manage child processes more effectively, particularly in complex bash scripts involving multiple child processes. A1: SIGCHLD is a signal sent to a parent process whenever one of its child processes terminates or stops. The primary use of this signal is to notify the parent about changes in the status of its child processes.
