I use this script, saved as \`rerun\`, to automatically re-execute a command whenever a file in the current directory changes:

```bash
 #!/usr/bin/sh

    while true; do
        reset;
        \"$@\";
        inotifywait -e MODIFY --recursive .
    done 
```

For example, if you invoke \`rerun make test\` then \`rerun\` will run \`make test\` whenever you save a file in your editor.
