Zsh外壳是最受欢迎的外壳之一。也称为“ Z壳”。尽管bash shell和Zsh shell都被称为功能强大的shell，但它们也根据用户的喜好有要求。
由于这两个外壳程序都在积极开发中，因此在这里过分具体是不明智的。 Zsh和Bash之间的一些重要区别如下：
| Zsh | Bash |
|---|---|
| Zsh provides advanced tab-completion features which are much faster and smarter (supports case insensitive completion with smart defaults). | Bash lacks some completion features comparatively to Zsh and is not as fast as Zsh. |
| Zsh is not installed by default in most of the Linux/UNIX machines. | Bash is a built-in shell in most of the Linux/UNIX machines, which makes it portable across different systems. |
| Zsh supports recursive path expansion. It means if there is only one path (let’s assume: /usr/local/bin), then we can type “cd /u/l/b” and press the tab button to access that path. | Bash does not provide support for recursive path expansion. However, there are some alternative ways like using vim or command completion (compgen -c). |
| Zsh has built-in spelling correction and approximate completion feature for the typing mistakes in directory names or command names. | Bash does not support spelling correction and completion features by default. |
| Zsh provides supports for several plugin frameworks and themes. | Bash has limited support for the plugin frameworks and themes. |
| In Zsh, ‘which command’ will reveal the definition of an alias, the source for a function, and the location of a command. | In Bash, ‘which command’ only reveals the location of a command. |
这就是我们可以区分Zsh和Bash的方式。
