Switching from zsh to bash on OSX, and back again?
提问by vpoola88
So Im learning to develop in Rails, and have discovered the power of zsh. However, for some of my other tasks, I wish to use normal Bash. Although they are the same, I just feel comfortable with the lay out of bash in some situations. How do I switch back and forth, or turn zsh on and off? Thanks!
所以我正在学习在 Rails 中开发，并且发现了 zsh 的强大功能。但是，对于我的其他一些任务，我希望使用普通的 Bash。虽然它们是相同的，但我只是在某些情况下对 bash 的布局感到满意。如何来回切换，或打开和关闭 zsh？谢谢！

You can just use execto replace your current shell with a new shell:
您可以使用exec新外壳替换当前外壳：
Switch to bash:
切换到bash：
exec bash
Switch to zsh:
切换到zsh：
exec zsh
This won't affect new terminal windows or anything, but it's convenient.
这不会影响新的终端窗口或任何东西，但很方便。

you can try chsh -s /bin/bashto set the bash as the default,
or chsh -s /bin/zshto set the zsh as the default.
您可以尝试chsh -s /bin/bash将bash设置为默认值，或者chsh -s /bin/zsh将zsh设置为默认值。

I switch between zsh and bash somewhat frequently. For a while, I used to have to source my bash_profile every switch. Then I found out you can (typically) do
我经常在 zsh 和 bash 之间切换。有一段时间，我曾经不得不在每次切换时获取我的 bash_profile。然后我发现你可以（通常）做
exec bash --login
or just
要不就
exec bash -l

if it is just a temporary switch
如果只是临时切换
you can use exec as mentioned above, but for more of a permanent solution.
您可以使用上面提到的 exec ，但更多的是永久解决方案。
you can use chsh -s /bin/bash(to switch to bash) and chsh -s /bin/zsh(to switch to zsh)
您可以使用chsh -s /bin/bash（切换到 bash）和chsh -s /bin/zsh（切换到 zsh）

zsh has a builtin command emulatewhich can emulate different shells by setting the appropriate options, although csh will never be fully emulated.
zsh 有一个内置命令emulate，它可以通过设置适当的选项来模拟不同的 shell，尽管 csh 永远不会被完全模拟。
emulate bash
perform commands
emulate -R zsh
The -R flag restores all the options to their default values for that shell.
-R 标志将所有选项恢复为该 shell 的默认值。

You should be able just to type bashinto the terminal to switch to bash, and then type zshto switch to zsh. Works for me at least.
您应该能够bash在终端中键入以切换到 bash，然后键入zsh以切换到 zsh。至少对我有用。
