fish is empty by default. To create a custom prompt create a file ~/. config/fish/functions/fish_prompt. fish and fill it with your prompt.
Configuration. To store configuration write it to a file called ~/. config/fish/config. fish .
To be able to run fish scripts from your terminal, you have to do two things. Add the following shebang line to the top of your script file: #!/usr/bin/env fish . Mark the file as executable using the following command: chmod +x <YOUR_FISH_SCRIPT_FILENAME> .
Switching to fish? If you wish to use fish (or any other shell) as your default shell, you need to enter your new shell's executable /usr/local/bin/fish in two places: add /usr/local/bin/fish to /etc/shells. change your default shell with chsh -s to /usr/local/bin/fish.
The comment sign is #, as glenn jackman suggested.
