Options
-c: Clear the screen before invoking the utility.-r: Reload a persistent child process (e.g., a server).-s: Evaluate the first argument using the interpreter specified bySHELL.
Examples

find src/ -name "*.c" | entr make
Run tests when JS files change:
git ls-files | grep '.js$' | entr npm test

Agent Notes
entr blocks the terminal. When using it as an agent:
1. Use process tool to run it in the background if you need to do other things.
2. Or use it for a quick "watch mode" session where you intend to monitor output for a while.
