FASTFETCH(1) FASTFETCH FASTFETCH(1) 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 Any combination of options can be made permanent by generating a configuration file: fastfetch --gen-config Informative -h, --help [command] Show this help message or help for a specific command -v, --version Show the full Fastfetch version --version-raw Show the raw version string (major.minor.patch) --list-config-paths List search paths for config files --list-data-paths List search paths for presets and logos --list-logos List available logos --list-modules List available modules --list-presets List available presets Presets can be loaded with "--config " --list-features List the supported features that fastfetch was compiled with Mainly for development --print-logos Show available logos --print-structure Show the default structure --format enum Set the output format -j, --json [bool] Enable or disable JSON output Shortcut for `--format json` --dynamic-interval num Keep Fastfetch running and refresh the output every milliseconds Set to 0 (default) to disable this behavior; does not work with --json -w, --watch [num] Alias of dynamic-interval, but the value is in seconds instead of milliseconds. If no value is provided, it defaults to 1 second Config -c, --config config Specify the config file or preset to load The file is searched in the order shown by "fastfetch --list- config-paths". Use "-" to read config from stdin, or "none" to disable further config loading. See also https://github.com/fastfetch-cli/fastfetch/wiki/Configuration for details --gen-config [path] Interactively generate a config file at the specified path Opens an interactive configuration UI when run in a terminal. Falls back to non-interactive generation when env-var `$NO_COLOR` is set or stdin/stdout is not a TTY. Defaults to "~/.config/fastfetch/config.jsonc".
