如何使 .bash_prompt 更改永久生效

Question

我无法正确设置提示。目前，我的主目录中有以下与点文件关联的符号链接。我假设我需要 source 才能.bash_prompt使此更改持久，但仍然没有结果。

我是不是链接的方向错误了？

.bash_profile .bash_profile -> Documents/Dotfiles/.bash_profile

export PATH=/usr/local/bin:/usr/local/sbin:$PATH

source ~/.bashrc

if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi

function http(){
  curl http://httpcode.info/$1;
}

alias fuck='eval $(thefuck $(fc -ln -1)); history -r'

complete -o "nospace" -W "Contacts Calendar Dock Finder Mail Safari iTunes SystemUIServer Terminal Twitter" killall;

.bashrc

source .bash_prompt

.bash_prompt .bash_prompt -> Documents/Dotfiles/.bash_prompt

#!/bin/bash

# Shell prompt based on the Solarized Dark theme.

# Heavily inspired by @necolas’s prompt: https://github.com/necolas/dotfiles
# iTerm → Profiles → Text → use 13pt Monaco with 1.1 vertical spacing.

Tl;dr，使用source .bash_prompt内部.bash_profile工作得很好，并解决了不相关的启动问题。
