When it comes to shell scripting on Unix-like operating systems, two shells dominate: Bash (Bourne Again Shell) and Zsh (Z Shell). If you are a programmer or system administrator, choosing one of the two significantly affects work efficiency and productivity.

Understanding the differences and similarities between these two shells will help you optimize your command line process. In addition, by understanding the characteristics of each shell, you can easily make wise decisions.

What are Bash and Zsh?

Bash is a popular system on both Linux and macOS. It is a powerful tool that you can use to interact with the operating system and run commands. You can also use Bash for shell commands, which automate tasks by writing scripts that contain more than one command.

Zsh (Z shell) is an extended version of Bash but with more features. It is the default shell on macOS, which is also increasingly popular on Linux systems.

 

How to switch from Bash to Zsh

If you're on a Linux system and want to switch to Zsh, start by using the package manager to install it. For example, on Debian or Ubuntu, use the following command:

sudo apt install zsh

After installing Zsh on the system, switch to it by running the following command:

chsh -s $(which zsh)

If you are using macOS, Zsh is already installed. To switch to it, run the following command:

chsh -s /bin/zsh

To switch back to Bash, replace Zsh with Bash in the command above.

To check which shell you are using, run the following command:

echo $SHELL

This helps confirm that you are using the desired shell.

In bash, key binding is done using '.inputrc' and 'bind buildin'.

Data binding is done using 'bindkey builtin'.

Things to consider when choosing between Zsh and Bash

  1. Compatibility and portability : Bash is the default shell on many Unix-based systems. This makes it a safer choice for cross-platform scripting. If you need a script to run on a large range of systems without modification, Bash is a better choice.
  2. Complexity and advanced features : Zsh offers advanced features such as associative arrays, expandable patterns, and advanced parameter expansion. This simplifies complex scripting tasks. If your script needs advanced string editing or data structures, Zsh is a better choice.
  3. Community and plugin ecosystem : Both Bash and Zsh have active communities, but Zsh has a stronger community and a scalable plugin and theme ecosystem. If you value customization, support from a vibrant community and plugins can benefit you significantly.
  4. Easy to learn : If you're new to shell scripting, Bash is a more accessible starting point. It has extensive documentation and resources ready for beginners. This makes learning the basics of shell scripting easier.
