Zsh, also known as Z shell, is a powerful command-line interpreter for Unix and Linux systems. It offers improved functionality and customization options compared to the traditional Bash shell. In this blog post, we will explore some sample Zsh command scripts to give you a better understanding of its capabilities.

1. Hello World Script

Let’s start with a simple “Hello World” script in Zsh:

#!/bin/zsh

echo "Hello, World!"

Save the above script in a file called hello.zsh. Make it executable using the chmod +x hello.zsh command. Then, run the script using ./hello.zsh, and you should see the output: “Hello, World!”.

2. Loop Script

Zsh supports various looping constructs. Here’s an example of a for loop that iterates over a list of numbers:

#!/bin/zsh

for i in {1..5}
do
    echo "Number: $i"
done

Save the above script in a file called loop.zsh, make it executable, and run it. You will see the output:

Number: 1
Number: 2
Number: 3
Number: 4
Number: 5

3. Command Line Arguments

Zsh allows you to pass arguments to your scripts from the command line. Here’s an example:

#!/bin/zsh

echo "Script Name: $0"
echo "First Argument: $1"
echo "Second Argument: $2"

Save the above script in a file called args.zsh, make it executable, and run it with two arguments: ./args.zsh Hello World. You will see the output:

Script Name: ./args.zsh
First Argument: Hello
Second Argument: World
