NAME
fastfetch - A fast and feature-rich system information tool similar to neofetch
SYNOPSIS
fastfetch [OPTIONS...]
DESCRIPTION
Fastfetch is a tool for displaying system information in a visually appealing way. Written primarily in
C, it focuses on performance and customizability while providing functionality similar to neofetch. It
supports Linux, Android, FreeBSD, macOS, and Windows 7 or newer.
CONFIGURATION
Fetch Structure
The structure defines which modules to display and in what order. It consists of module names separated
by colons (:). For example: title:separator:os:kernel:uptime
To list all available modules, use --list-modules
Config Files
Fastfetch uses JSONC (JSON with Comments) for configuration files. These files must have the .jsonc
extension.
You can generate a default config file using --gen-config. By default, the config file is saved at
~/.config/fastfetch/config.jsonc.
The configuration/preset files are searched in the following locations (in order):
1. Relative to the current working directory
2. Relative to ~/.local/share/fastfetch/presets/
3. Relative to /usr/share/fastfetch/presets/
For detailed information on logo options, module configuration, and formatting, visit:
https://github.com/fastfetch-cli/fastfetch/wiki/Configuration
Fastfetch provides several built-in presets. List them with --list-presets.
JSON Schema
A JSON schema is available for editor intelligence when editing the configuration file. Add the following
line at the beginning of your config file:
"$schema": "https://github.com/fastfetch-cli/fastfetch/raw/dev/doc/json_schema.json"
OPTIONS
Options are parsed in a case-insensitive manner. For example, --logo-type and --LOGO-TYPE are treated
identically.
Arguments in square brackets are optional. Optional boolean arguments default to 'true' when specified
without a value.
For more detailed information about a specific option, use: fastfetch -h <option_name_without_dashes>
Any combination of options can be made permanent by generating a configuration file: fastfetch <options>
--gen-config
