```bash
#!/bin/bash
less --tabs 4 -RF "$@"
less --tabs 4 -R "$@"
```
**Note**: By default, if the pager is set to `less`, `bat` will pass the following command line
options to the pager: `-R`/`--RAW-CONTROL-CHARS`, `-F`/`--quit-if-one-screen` and `-X`/`--no-init`.
The first (`-R`) is needed to interpret ANSI colors correctly. The second option (`-F`) instructs
less to exit immediately if the output size is smaller than the vertical size of the terminal.
This is convenient for small files because you do not have to press `q` to quit the pager. The
third option (`-X`) is needed to fix a bug with the `--quit-if-one-screen` feature in old versions
of `less`. Unfortunately, it also breaks mouse-wheel support in `less`. If you want to enable
mouse-wheel scrolling, you can either pass just `-R` (as in the example above, this will disable
the quit-if-one-screen feature), or you can use a recent version of `less` and pass `-RF` which
will hopefully enable both quit-if-one-screen and mouse-wheel scrolling.
If scrolling still doesn't work for you, you can try to pass the `-S` option in addition.
## Using `bat` on Windows
`bat` mostly works out-of-the-box on Windows, but a few features may need extra configuration.
