Fastfetch is a [neofetch](https://github.com/dylanaraps/neofetch)-like tool for fetching system information and displaying it prettily. It is written mainly in C, with performance and customizability in mind. Currently, Linux, Android, FreeBSD, macOS, SunOS and Windows 7+ are supported.
* Debian / Ubuntu: Download `fastfetch-linux-<proper architecture>.deb` from [Github release page](https://github.com/fastfetch-cli/fastfetch/releases/latest) and double-click it (for Ubuntu 20.04 or newer and Debian 11 or newer).
If fastfetch is not packaged for your distro or an outdated version is packaged, [linuxbrew](https://brew.sh/) is a good alternative: `brew install fastfetch`
You may also download the program directly from [the GitHub releases page](https://github.com/fastfetch-cli/fastfetch/releases/latest) in the form of an archive file.
* Run it with [all supported modules](https://github.com/fastfetch-cli/fastfetch/wiki/Support+Status#available-modules) and find what interests you: `fastfetch -c all.jsonc`
Fastfetch uses the JSONC (or JSON with comments) for configuration. [See Wiki for detail](https://github.com/fastfetch-cli/fastfetch/wiki/Configuration). There are some premade config files in [`presets`](presets), including the ones used for the screenshots above. You can load them using `-c <filename>`. Those files can serve as examples of the configuration syntax.
3. Fastfetch has a greater number of features, though by default fastfetch only has a few modules enabled; use `fastfetch -c all` to find what you want.
4. Fastfetch is more configurable. You can find more information in the Wiki: <https://github.com/fastfetch-cli/fastfetch/wiki/Configuration>.
5. Fastfetch is more polished. For example, neofetch prints `555 MiB` in the Memory module and `23 G` in the Disk module, whereas fastfetch prints `555.00 MiB` and `22.97 GiB` respectively.
A local IP (10.x.x.x, 172.x.x.x, 192.168.x.x) has nothing to do with privacy. It only makes sense if you are on the same network, for example, if you connect to the same Wi-Fi network.
Actually the `Local IP` module is the most useful module for me personally. I (@CarterLi) have several VMs installed to test fastfetch and often need to SSH into them. I have fastfetch running on shell startup and I never need to type `ip addr` manually.
If you really don't like it, you can disable the `Local IP` module in `config.jsonc`.
`Fastfetch` does not generate config file automatically. You can use `fastfetch --gen-config` to generate one. The config file will be saved in `~/.config/fastfetch/config.jsonc` by default. See [Wiki for detail](https://github.com/fastfetch-cli/fastfetch/wiki/Configuration).
This is an example that [changes size prefix from MiB / GiB to MB / GB](https://github.com/fastfetch-cli/fastfetch/discussions/1014). Editor used: [helix](https://github.com/helix-editor/helix)
[Here is the documentation](https://github.com/fastfetch-cli/fastfetch/wiki/Json-Schema). It is generated from [JSON schema](https://github.com/fastfetch-cli/fastfetch/blob/dev/doc/json_schema.json) but you won't like it.
Fastfetch uses `format` to generate output. For example, to make the `GPU` module show only the GPU name (leaving other information undisplayed), you can use
### Q: Fastfetch runs in white and black on shell startup. Why?
This issue usually happens when using fastfetch with `p10k`. There are known incompatibility between fastfetch and p10k instant prompt.
The p10k doc clearly states that you should NOT print anything to stdout after `p10k-instant-prompt` is initialized. You should either put `fastfetch` before initialization of `p10k-instant-prompt` (recommended)
You can always use `fastfetch --pipe false` to force fastfetch running in colorful mode.
### Q: Fastfetch shows less dpkg packages than neofetch, is it a bug?
Neofetch incorrectly counts `rc` packages ( the package has been removed, but that the configuration files remain ). Bug https://github.com/dylanaraps/neofetch/issues/2278
Try upgrading `pci.ids`: Download <https://pci-ids.ucw.cz/v2.2/pci.ids> and overwrite file `/usr/share/hwdata/pci.ids`. For AMD GPUs, you should also upgrade `amdgpu.ids`: Download <https://gitlab.freedesktop.org/mesa/drm/-/raw/main/data/amdgpu.ids> and overwrite file `/usr/share/libdrm/amdgpu.ids`
Alternatively, you may try to use `fastfetch --gpu-driver-specific`, so that `fastfetch` will try to ask the driver for GPU name if supported.
### Q: I want feature A / B / C. Will fastfetch support it?
Fastfetch is a system information tool. We only accept hardware or system level software feature requests. For most personal uses, I recommend using `Command` module to detect it yourself, which can be used to grab output from a custom shell script:
```jsonc
// This module shows the default editor
{
"modules": [
{
"type": "command",
"text": "$EDITOR --version | head -1",
"key": "Editor"
}
]
}
```
