Finally, use `bat --list-themes` to check if the new themes are available.
### Using a different pager
`bat` uses the pager that is specified in the `PAGER` environment variable. If this variable is not
set, `less` is used by default. If you want to use a different pager, you can either modify the
`PAGER` variable or set the `BAT_PAGER` environment variable to override what is specified in
`PAGER`.
If you want to pass command-line arguments to the pager, you can also set them via the
`PAGER`/`BAT_PAGER` variables:
```bash
export BAT_PAGER="less -RF"
```
Instead of using environment variables, you can also use `bat`s [configuration file](https://github.com/sharkdp/bat#configuration-file) to configure the pager (`--pager` option).
**Note**: By default, if the pager is set to `less` (any no command-line options are specified),
`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.
## Configuration file
`bat` can also be customized with a configuration file. The location of the file is dependent
on your operating system. To get the default path for your system, call
```
bat --config-file
```
Alternatively, you can use the `BAT_CONFIG_PATH` environment variable to point `bat` to a
non-default location of the configuration file:
```bash
export BAT_CONFIG_PATH="/path/to/bat.conf"
```
### Format
The configuration file is a simple list of command line arguments. Use `bat --help` to see a full list of possible options and values. In addition, you can add comments by prepending a line with the `#` character.
Example configuration file:
```bash
# Set the theme to "TwoDark"
--theme="TwoDark"
# Show line numbers, Git modifications and file header (but no grid)
--style="numbers,changes,header"
# Use italic text on the terminal (not supported on all terminals)
--italic-text=always
# Add mouse scrolling support in less (does not work with older
# versions of "less")
--pager="less -FR"
# Use C++ syntax (instead of C) for .h header files
--map-syntax h:cpp
# Use "gitignore" highlighting for ".ignore" files
--map-syntax .ignore:.gitignore
```
## Using `bat` on Windows
`bat` mostly works out-of-the-box on Windows, but a few features may need extra configuration.
### Paging
Windows only includes a very limited pager in the form of `more`. You can download a Windows binary
for `less` [from its homepage](http://www.greenwoodsoftware.com/less/download.html) or [through
Chocolatey](https://chocolatey.org/packages/Less). To use it, place the binary in a directory in
your `PATH` or [define an environment variable](#using-a-different-pager).
### Colours
Windows 10 natively supports colours in both `conhost.exe` (Command Prompt) and PowerShell since
[v1511](https://en.wikipedia.org/wiki/Windows_10_version_history#Version_1511_(November_Update)), as
well as in newer versions of bash. On earlier versions of Windows, you can use
[Cmder](http://cmder.net/), which includes [ConEmu](https://conemu.github.io/).
**Note:** The Git and MSYS versions of `less` do not correctly interpret colours on Windows. If you
don’t have any other pagers installed, you can disable paging entirely by passing `--paging=never`
or by setting `BAT_PAGER` to an empty string.
### Cygwin
`bat` on Windows does not natively support Cygwin's unix-style paths (`/cygdrive/*`). When passed an absolute cygwin path as an argument, `bat` will encounter the following error: `The system cannot find the path specified. (os error 3)`
This can be solved by creating a wrapper or adding the following function to your `.bash_profile` file:
