Two, fish configuration

Fish does not load ~/.bash_profile, there are two ways to add environment variables

1. Input fish_configwill open the configuration page, add in abbreviations
   
2. vi ~/.config/fish/config.fish, Regardless of whether this file exists or not. The syntax for adding is not the same, such as modifying my original one php, adding set -x PATH /usr/local/Cellar/[email protected]/7.1.26/bin $PATH, and re-entering after exiting fish.
3. If it is only a remote server and cannot open the browser, you can use fish_promptmethods to modify the cursor style, for example:

   function fish_prompt
       set_color $fish_color_cwd
       echo -n (basename $PWD)
       set_color normal
       echo -n ' ) '
   end
