Trigger – run a shell command repeatedly on file changes

In plain words

Trigger is a command-line tool that monitors files for changes and automatically executes a shell command whenever a change is detected. It is designed for developers who want to automate repetitive tasks during development, such as recompiling code or running tests without manual intervention. The tool watches specified files and directories, running custom commands each time modifications occur, making it useful for streamlining development workflows.

It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.
