ping fish 色

brew install grc

~/.config/fish/config.fish
source /usr/local/etc/grc.fish

これやると

export CLICOLOR=1 export LSCOLORS="GxFxCxDxBxegedabagaced" とかで ls(ll）のフォルダの色を変更していた場合　にフォルダの色がつかなくなるので

下記からlsを外しておく

vim /usr/local/etc/grc.fish

#!/usr/bin/env fish
#
# To load in ~/.config/fish/fish.conf or a new file in
# ~/.config/fish/conf.d add:
# source /etc/grc.fish (path may depend on install method)
