Zsh (Z shell) is a powerful and feature-rich shell for Unix-like systems, including Linux. It is known for its enhanced command-line completion, customization options, and scripting capabilities. In this blog post, we will explore how to execute commands within Zsh scripts in Linux.

Creating a Zsh Script

To begin, let’s create a simple Zsh script. Open a text editor and create a new file, let’s call it my_script.zsh. Alternatively, you can use the terminal to create the file:

$ touch my_script.zsh
$ nano my_script.zsh

In the my_script.zsh file, we can add the commands we want to execute. For example, let’s write a script that prints “Hello, World!” to the terminal:

#!/bin/zsh

echo "Hello, World!"

Save and exit the text editor.

Making the Script Executable

Before executing the Zsh script, we need to make it executable. In the terminal, run the following command:

$ chmod +x my_script.zsh

This grants the execute permission to the file.

Executing the Zsh Script

To execute the Zsh script, simply run the following command in the terminal:

$ ./my_script.zsh

The script will be executed using the Zsh interpreter specified in the shebang (the #!/bin/zsh line at the beginning of the script) and the output “Hello, World!” will be displayed in the terminal.

Passing Arguments to the Script

Zsh scripts can also accept command-line arguments. Let’s modify our script to take a name as an argument and display a personalized greeting. Update the my_script.zsh file as follows:

#!/bin/zsh

name=$1
echo "Hello, $name!"

Save the file and make it executable using the chmod command mentioned earlier.

To execute the updated script and pass an argument, use the following command:

$ ./my_script.zsh John

The script will greet the provided name, and the output will be “Hello, John!”.

Conclusion

Executing commands within Zsh scripts in Linux is a simple and straightforward process. We can create scripts, make them executable, and run them using the Zsh interpreter. Zsh’s scripting capabilities allow for more complex automation and customization tasks. Experiment with Zsh scripts to optimize your command-line workflow and boost productivity.
