Zsh vs. Bash — What's the Difference?

Difference Between Zsh and Bash


Key Differences

Zsh (Z Shell) is known for its interactive features and customization options, making it popular among users who prefer a rich interface. Bash (Bourne Again SHell), on the other hand, is renowned for its efficiency and widespread use, particularly in scripting and programming environments.
Zsh offers advanced features like better auto-completion, spell correction, and theme support, enhancing user experience. Bash is more focused on script execution and backward compatibility, often used in programming and system administration due to its stability and predictability.
While Zsh provides a more user-friendly and customizable experience, Bash is known for its scripting capabilities, being the default shell in many Unix-like systems. Zsh's syntax is quite similar to Bash but includes additional features and enhancements.
Bash has a wider presence in the Linux community due to its default inclusion in many distributions and its reputation for script compatibility. Zsh, although gaining popularity, especially with its inclusion as the default shell in macOS, is more often chosen for interactive use rather than scripting.
In terms of scripting, Bash scripts are generally more portable and widely supported across different systems, whereas Zsh scripts may not be as universally compatible due to Zsh's extended feature set.
