Randomly select fastfetch config

[doctorfree]

I have several fastfetch configs and wrote a simple script to randomly select among them. To use this script the configuration files must be named ~/.config/fastfetch/config-<name>.jsonc. Without arguments ffetch displays using the default config. To select a random config, run ffetch -r. To specify a config, run ffetch -c config-<name>.

Enjoy!

#!/usr/bin/env bash
#
# ffetch - Display system info using fastfetch or neofetch
#          Random configuration selection assumes configs are named:
#            'config-*` in ~/.config/fastfetch/ or ~/.config/neofetch/
#          Use fastfetch if found, otherwise use neofetch

#
# Usage: ffetch [-c config] [-r] [-u]
# Where:
# 	-c 'config' specifies a configuration file to use
# 	  'config' can be the full path or name of a configuration
# 	-r indicates select configuration file randomly
# 	-u displays this usage messge and exits

You may want to replace CONFDIR="${HOME}/.config/${FETCH}" for CONFIGDIR="${XDG_CONFIG_HOME:-$HOME/.config}/${FETCH}"" as fastfetch is XDG Base dir compliant.

Yes I have XDG Vigilante as my nickname lol.

Done (with slight corrections). Good suggestion. Folks might also need to worry about my use of xterm-kitty as TERM.

The ffetch script, fastfetch configs, and other user configuration are maintained in yadm repos at https://github.com/doctorfree/dotfiles-macbookpro and https://github.com/doctorfree/dotfiles-linux

bravo

I used this:

I could make it more robust by listing from fastfetch --list-data-paths
and then listing all files find $(fastfetch --list-data-paths) -type f, then shuffling. But I like one liners

Get a random preset

fastfetch --config $(printf "%s\n" examples/{6,7,9,13,17,20,21,22} | shuf -n 1)
