FASTFETCH(1) Fastfetch man page FASTFETCH(1) NAME fastfetch - A maintained, feature-rich and performance oriented, neo- fetch like system information tool SYNOPSIS fastfetch [OPTIONS] WIKI Fastfetch github wiki : https://github.com/fastfetch-cli/fast- fetch/wiki/Configuration CONFIGURATION Fetch Structure The structure of a fetch describes the modules that should be included in the output. It consists of a string of modules, separated by a colon (:). To list all available modules, use --list-modules. Config Files Fastfetch uses JSONC based format for configuration. Fastfetch doesn't generate config file automatically; it should be generated manually by --gen-config. The config file will be saved in ~/.config/fast- fetch/config.jsonc by default. A JSONC config file is a JSON file that also supports comments with (// and /* */). Those files must have the extension '.jsonc'. The specified configuration/preset files are searched in the following order: 1. relative to the current working directory 2. relative to ~/.local/share/fastfetch/presets/ 3. relative to /usr/share/fastfetch/presets/ Fastfetch provides some default presets. List them with --list-presets. OPTIONS Parsing is not case sensitive. E.g. --logo-type is equal to --LOGO- TYPE. If a value is between square brackets, it is optional. An optional boolean value defaults to true if not specified. More detailed help messages for each options can be printed with -h <option_without_dash_prefix>. All options can be made permanent with command fastfetch <options> --gen-config.
