# Usage
# 1. Set colors and/or icons to your liking
# 2. preview-tui-ext uses the script to prepend icon to directory listings
# 3. Aditionally you can consider adding it to your PATH and/or FZF_DEFAULT_COMMAND to
# make it work with various fzf plugins (make sure you also add --ansi to your FZF_DEFAULT_OPTS)
# 2. Pipe any directory listing to iconlookup and it will output prepended icons
# 3. preview-tui-ext uses the script to prepend icon to directory listings
# 4. Aditionally you can consider adding it to your PATH and/or FZF_DEFAULT_COMMAND to
# make it work with various fzf plugins (make sure you also add --ansi to your FZF_DEFAULT_OPTS)
