diein

diein is a command-line utility that allows users to specify files and directories to be watched for changes. When a change is detected in any of the specified paths, diein can be configured to execute a command. This is useful for automating tasks that need to be performed in response to file modifications, such as recompiling code, restarting a server, or running tests.

The utility works by monitoring file system events. When a file is created, deleted, modified, or moved within the watched directories, diein triggers the predefined action. The user typically provides a list of paths and the command to execute as arguments to the diein command. This makes it a flexible tool for developers and system administrators seeking to streamline their workflows.

diein is designed to be simple and efficient. It does not require complex configuration files and can be easily integrated into shell scripts or build processes. Its primary purpose is to automate repetitive tasks, saving time and reducing the potential for human error. The tool is often used in development environments for tasks like live reloading web pages or triggering automated builds upon code commits.
