In Linux, the Zsh shell (Z shell) offers a wide range of built-in functions that provide convenience and enhance productivity for users. These functions are already included in the Zsh shell, eliminating the need for external commands. In this blog post, we will explore some useful and commonly used Zsh built-in functions.

1. cd

The cd function is used to change the current working directory. It allows you to navigate to different directories in your system. Here’s an example:

cd /path/to/directory

2. echo

The echo function is used to display text or messages on the terminal. It is often used for printing variable values or displaying simple information. Here’s an example:

echo "Hello, World!"

3. alias

The alias function allows you to create your own custom commands or abbreviations for frequently used commands. It helps to save time by reducing the need to type lengthy commands repeatedly. Here’s an example:

alias ll="ls -alF"

Now, whenever you type ll on the terminal, it will be replaced by ls -alF command.

4. source

The source function is used to execute commands from a file in the current shell session. It is commonly used to load environment variables or configuration files. Here’s an example:

source ~/.bashrc

The command above will load the ~/.bashrc file in the current shell session.

5. history

The history function displays a list of previously executed commands. It is helpful for finding and re-executing commands without retyping them. Here’s an example:

history

6. jobs

The jobs function lists the currently running jobs or tasks in the background. It is useful for managing and controlling background processes. Here’s an example:

jobs

Conclusion

Zsh built-in functions offer a powerful set of tools and capabilities that make the Linux command line experience more efficient and convenient. From changing directories to creating custom commands, these functions help streamline your workflow and improve productivity. Experiment with these functions and explore the vast possibilities they provide within the Zsh shell.
