Simply type source ~/.bash_profile
只需输入 source ~/.bash_profile
Alternatively, if you like saving keystrokes you can type . ~/.bash_profile
或者，如果你喜欢保存击键，你可以输入 . ~/.bash_profile

. ~/.bash_profile
Just make sure you don't have any dependencies on the current state in there.
只要确保你对那里的当前状态没有任何依赖。

Simply type:
只需键入：
. ~/.bash_profile
However, if you want to source it to run automatically when terminal starts instead of running it every time you open terminal, you might add . ~/.bash_profileto ~/.bashrcfile.
但是，如果您想让它在终端启动时自动运行而不是每次打开终端时都运行它，您可以添加. ~/.bash_profile到~/.bashrc文件中。
Note:
笔记：
When you open a terminal, the terminal starts bash in (non-login) interactive mode, which means it will source ~/.bashrc.
当您打开终端时，终端会以（非登录）交互模式启动 bash，这意味着它将提供 .bashrc 文件~/.bashrc。
~/.bash_profileis only sourced by bash when started in interactive login mode. That is typically only when you login at the console (Ctrl+Alt+F1..F6), or connecting via ssh.
~/.bash_profile仅在以交互登录模式启动时由 bash 提供。这通常是只有当你登录在控制台（Ctrl+ Alt+ F1... F6），或通过连接ssh。

I like the fact that after you have just edited the file, all you need to do is type:
我喜欢这样一个事实，即在您刚刚编辑文件后，您需要做的就是输入：
. !$
This sources the file you had just edited in history. See What is bang dollar in bash.
这是您刚刚在历史记录中编辑的文件的来源。请参阅什么是 bash 中的 bang 美元。

You can also use this command to reload the ~/.bash_profile for that user. Make sure to use the dash.
您还可以使用此命令为该用户重新加载 ~/.bash_profile。确保使用破折号。
su - username

If you don't mind losing the history of your current shell terminal you could also do
如果您不介意丢失当前 shell 终端的历史记录，您也可以这样做
bash -l
bash -l
That would fork your shell and open up another child process of bash. The -lparameter tells bash to run as a login shell, this is required because .bash_profile will not run as a non-login shell, for more info about this read here
这将 fork 你的 shell 并打开另一个 bash 子进程。该-l参数告诉 bash 作为登录 shell 运行，这是必需的，因为 .bash_profile 不会作为非登录 shell 运行，有关此的更多信息，请阅读此处
If you want to completely replace the current shell you can also do:
如果要完全替换当前的 shell，还可以执行以下操作：
exec bash -l
exec bash -l
The above will not fork your current shell but replace it completely, so when you type exitit will completely terminate, rather than dropping you to the previous shell.
以上不会分叉您当前的 shell 而是完全替换它，因此当您键入exit它时，它将完全终止，而不是让您回到以前的 shell。

Add alias bashs="source ~/.bash_profile"in to your bash file.
So you can call bashsfrom next time
添加alias bashs="source ~/.bash_profile"到您的 bash 文件中。这样你bashs下次就可以打电话了
