You can just use <code>exec</code> to replace your current shell with a new shell:

Switch to <code>bash</code>:

<pre><code>exec bash
</code></pre>

Switch to <code>zsh</code>:

<pre><code>exec zsh
</code></pre>

This won't affect new terminal windows or anything, but it's convenient.

zsh has a builtin command <code>emulate</code> which can emulate different shells by setting the appropriate options, although csh will never be fully emulated.

<pre><code>emulate bash
perform commands
emulate -R zsh
</code></pre>

The -R flag restores all the options to their default values for that shell.

In Mac OS Catalina default interactive shell is zsh. 
To change shell to zsh from bash:

<pre><code>chsh -s /bin/zsh
</code></pre>

Then you need to enter your Mac password. Quit the terminal and reopen it. To check whether it's changed successfully to ssh, issue the following command.

<pre><code>echo $SHELL
</code></pre>

If the result is /bin/zsh, your task is completed.

To change it back to bash, issue the following command on terminal.

<pre><code>chsh -s /bin/bash
</code></pre>

Verify it again using <code>echo $SHELL</code>. Then result should be /bin/bash.

You should be able just to type <code>bash</code> into the terminal to switch to bash, and then type <code>zsh</code> to switch to zsh. Works for me at least.

I'm learning to develop in Rails, and have discovered the power of <code>zsh</code>. However, for some of my other tasks, I wish to use normal <code>bash</code>.
Although they are the same, I just feel comfortable with the layout of <code>bash</code> in some situations.
How do I switch back and forth, or turn <code>zsh</code> on and off?

Switching from zsh to bash on OS X, and back again?

我正在学习在Rails中进行开发，并发现了zsh的强大功能。然而，对于我的其他一些任务，我希望使用普通的bash。虽然它们是一样的，但我只是在某些情况下对bash的布局感到舒服。如何来回切换，或打开和关闭zsh？
