The article explains using the `timeout` command in Linux for process management, focusing on sending `SIGTERM` followed by `SIGKILL`. It describes `SIGTERM` as a grace period shutdown and `SIGKILL` as a forceful process termination. The command syntax is detailed with examples to demonstrate effective process control, ensuring resources are not consumed unnecessarily by lingering processes.

The article offers insights on forwarding trapped UNIX signals, like `SIGTERM`, to child processes in Bash scripts, crucial for ensuring graceful terminations in Linux systems. It explains signal trapping and outlines how to use the `kill` command to send signals to a child process identified by PID, including practical script examples.

The blog discusses how to handle the SIGTERM signal in Bash scripts to prevent abrupt termination during critical cleanup operations. Using the `trap` command, the article illustrates how to catch and manage SIGTERM to ensure vital tasks are completed successfully, thus avoiding data loss and promoting robust system behavior.

The article discusses how to use the `timeout` command in Linux to set execution limits on system processes and integrate cleanup operations using a signal trap for SIGTERM. This ensures graceful process termination, enhancing system stability and preventing resource leaks. Examples and a script demonstrate the application of these techniques effectively.

This article delves into Linux signal handling using `trap` and `kill -TERM $!` in Bash scripts, explaining methods to manage inter-process communication such as `SIGINT` and `SIGTERM`. It covers setting traps in parent scripts to catch signals and forward them via `kill` to a child process, ensuring that scripts can handle unexpected terminations gracefully.
