更改 .bashrc 和 .bash_profile 后终端无法正确更新

Question

I'm just trying to update my.bashrc and.bash_profile file on my new mac. My files look like so:

//.bash_rc

orange=$(tput setaf 166);
yellow=$(tput setaf 228);
green=$(tput setaf 71);
white=$(tput setaf 15);
bold=$(tput bold);
reset=$(tput sgr0);

PS1="\[${bold}\]\n";
PS1+="\[${orange}\]\u";  # username
PS1+="\[${white}\] at ";
PS1+="\[${yellow}\]\h";  # host
PS1+="\[${white}\] in ";
PS1+="\[${green}\]\W :";   # working directory
PS1+="\n";
PS1+="\[${white}\]\$ \[${reset}\]"; # '$' and reset color
export PS1;

//.bash_profile

if [ -f ~/.bashrc ]; then
    source ~/.bashrc
fi

My terminal looks like this:

I can't figure out what I've entered wrong. Any help appreciated. Thanks

Answer 1

First, you are using zsh , not bash ; prompts are configured entirely differently.

Second, you need not export PS1 , as any process that cares about its value will be sourcing .zshrc .

The following should work, placed in .zshrc :

# The variables aren't necessary, but retained for
# ease of updating. You could specify %F{15} directly
# for %F{$white}, e.g.
orange=166
yellow=228
green=71
white=15

PS1=$'%B\n'
PS1+="%F{$orange}%n"
PS1+="%F{$white} at "
PS1+="%F{$yellow}%m";
PS1+="%F{$white} in "
PS1+="%F{$green}%~ :"
PS1+=$'\n'
PS1+="%F{$white}%# %f%b"

%B and %b turn bold on and off, respectively. %F{...} changes the current foreground color; %f resets to the terminal default. The \ escapes from bash are replaced with % escapes. You don't need the zsh equivalent of \[...\] anywhere, because you aren't using any raw byte sequences to control formatting.

The entire thing could be reduced to a single line:

PS1=$'%B\n%F{166}%n%F{15} at %F{228}%m%F{15} in %F{71}%~ :\n%F{15}%# %f%b'

though the longer version is more maintainable.

Finally, note that (unlike bash ) zsh sources .zshrc for all interactive shells. If it's also a login shell, it sources .zprofile , before, not instead of, .zshrc .
