Want to turn your plain log file output into a colorful format for easier reading? Try bat instead of cat:
```
cat /path/to/app.log # old
bat /path/to/app.log # wow
```

BTW, the `bat` or `batcat` is written in Rust lang and needs to be installed using your favorite package manager like APT, DNF, APK, PKG, port, etc on your Linux, macOS or Unix.
