fish_prompt - define the appearance of the command line prompt
function fish_prompt
...
end
The fish_prompt function is executed when the prompt is to be shown, and
the output is used as a prompt.
The exit status of commands within fish_prompt will not
modify the value of $status outside of the fish_prompt function.
fish ships with a number of example prompts that can be
chosen with the fish_config command.
A simple prompt:
function fish_prompt -d "Write out the prompt"
# This shows up as USER@HOST /home/user/ >, with the directory colored
# $USER and $hostname are set by fish, so you can just use them
# instead of using `whoami` and `hostname`
printf '%s@%s %s%s%s > ' $USER $hostname \
(set_color $fish_color_cwd) (prompt_pwd) (set_color normal)
end
