FASTFETCH(1) FASTFETCH FASTFETCH(1) NAME fastfetch - A fast and feature-rich system information tool similar to neo- fetch SYNOPSIS fastfetch [OPTIONS...] DESCRIPTION Fastfetch is a tool for displaying system information in a visually appeal- ing way. Written primarily in C, it focuses on performance and customiz- ability 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 con- sists of module names separated by colons (:). For example: title:separa- tor: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 format- ting, 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 config- uration file. Add the following line at the beginning of your config file: "$schema": "https://github.com/fastfetch-cli/fast- fetch/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 de- fault 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 configura- tion file: fastfetch <options> --gen-config Informative -h, --help [command] Display this help message or help for a specific command -v, --version Show the full version of fastfetch --version-raw Display 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 presets that fastfetch knows about Presets can be loaded with "--config <preset-name>" --list-features List the supported features that fastfetch was compiled with Mainly for development --print-logos Display available logos --print-structure Display the default structure --format enum Set output format -j, --json [bool] Enable or disable JSON output Shortcut for `--format json` --dynamic-interval num Keep fastfetch open and update the output every <num> milliseconds 0 (default) to disable the behavior; don't work with --json Config -c, --config config Specify the config file or preset to load The file will be searched according to the order shown by "fast- fetch --list-config-paths". Use "-" to read config from stdin or "none" to disable further config loading.
