Shell steps (sh, bat) in Jenkins - Mini Project: Build & Apply

Using Shell Steps in Jenkins Pipeline

📖 Scenario: You are setting up a Jenkins pipeline to automate simple shell commands. This will help you understand how to run shell scripts inside Jenkins jobs.

🎯 Goal: Build a Jenkins pipeline script that runs shell commands using sh steps on Linux or macOS, and bat steps on Windows agents.

📋 What You'll Learn

Create a Jenkins pipeline script with a pipeline block

Use a stage named Setup to run shell commands

Use sh step to run a Linux/macOS shell command

Use bat step to run a Windows batch command

Print the output of the commands in the Jenkins console

💡 Why This Matters

🌍 Real World

Jenkins pipelines automate software builds and deployments by running shell commands on build agents.

💼 Career

Knowing how to use <code>sh</code> and <code>bat</code> steps is essential for DevOps engineers to automate tasks across different operating systems.

1

Create a Jenkins pipeline with a pipeline block

Write a Jenkins pipeline script starting with a pipeline block and an empty agent any section.

Jenkins

pipeline {
    agent any
    // Your code here
}

Need a hint?

Start with pipeline { and add agent any inside it.

2

Add a stage named Setup

Inside the pipeline block, add a stages block with one stage named Setup.

Jenkins

pipeline {
    agent any
    stages {
        // Your code here
    }
}

Need a hint?

Add stages {} and inside it a stage('Setup') { steps { } } block.

3

Add a sh step to run echo Hello from Linux

Inside the steps block of the Setup stage, add a sh step that runs the command echo Hello from Linux.

Jenkins

pipeline {
    agent any
    stages {
        stage('Setup') {
            steps {
                // Your code here
            }
        }
    }
}

Need a hint?

Use sh 'echo Hello from Linux' inside steps {}.

4

Add a bat step to run echo Hello from Windows

Below the sh step inside the steps block, add a bat step that runs the command echo Hello from Windows.

Jenkins

pipeline {
    agent any
    stages {
        stage('Setup') {
            steps {
                sh 'echo Hello from Linux'
                // Your code here
            }
        }
    }
}

Need a hint?

Add bat 'echo Hello from Windows' below the sh step.
