It seems that I do not have it active, since I get

Run the following code, for instance to change your shell to the newest Bash installed by MacPorts
运行以下代码，例如将您的 shell 更改为 MacPorts 安装的最新 Bash
chsh -s /opt/local/bin/bash
If that gives you the message,
如果这给了你信息，
"
non-standard shell"
“
non-standard shell”
you will need to add
你需要添加
/opt/local/bin/bash
to
到
/etc/shells
Note that /etc/shellsis just a text file, so you can edit it directly if you authenticate as root. You can programmatically change it by the command
请注意，这/etc/shells只是一个文本文件，因此如果您以 root 身份进行身份验证，则可以直接编辑它。您可以通过命令以编程方式更改它
sudo -s
Password:
# echo /opt/local/bin/bash >> /etc/shells
If your first chsh command failed, run it now again if you managed to change the above file.
如果您的第一个 chsh 命令失败，如果您设法更改了上述文件，请立即再次运行它。

I'm guessing it's installed but not being used as your login shell.
我猜它已安装但未用作您的登录外壳。
You can change the shell using dscl on the command line.
您可以在命令行上使用 dscl 更改外壳。
At the dscl prompt type the following:
在 dscl 提示符下键入以下内容：
list Local/Default/Users
read Local/Default/Users/<your username here>
change Local/Default/Users/<your username here> UserShell /bin/bash /opt/local/bin/bash
I have another example of dscl use on my blogif it helps.
如果有帮助，我的博客上还有另一个使用 dscl 的示例。

You can switch your login shell, from your existing Mac OS X login shell (by default its /bin/bashshipped with Mac OS X), to MacPorts /opt/local/bin/bashjust by using the following shell script:
只需使用以下 shell 脚本，您就可以将登录 shell 从现有的 Mac OS X 登录 shell（默认情况下/bin/bash随 Mac OS X 一起提供）切换到 MacPorts /opt/local/bin/bash：
#!/opt/local/bin/bash
if [ `grep /opt/local/bin/bash /etc/shells` ];
then
echo /opt/local/bin/bash | chsh -s /opt/local/bin/bash;
else
echo /opt/local/bin/bash | sudo tee -a /etc/shells;
chsh -s /opt/local/bin/bash;
fi
