• Description:
  A freestyle job in Jenkins allows you to execute basic automation tasks such as running shell scripts, compiling code, copying files, or performing simple build operations. In this task, we create a Freestyle project and configure a simple Shell command that prints a message to verify that Jenkins is working correctly.

•  Step 1 — Open the Jenkins dashboard
   Start Jenkins and open a browser to http://localhost:8080 (or your Jenkins server URL). You should see the Jenkins home page.
•  Step 2 — Create a new job
   On the left menu click New Item to begin creating a new job.
•  Step 3 — Name the job
   In the Enter an item name field type first-project.
•  Step 4 — Choose job type
   Select Freestyle project and click OK.
•  Step 5 — Find the Build section
   On the job configuration page scroll down until you reach the Build section.
•  Step 6 — Add an “Execute shell” build step
   Click Add build step and choose Execute shell from the dropdown.
•  Step 7 — Enter the shell command
   In the shell text box type the command:
   echo "Hello Jenkins!"
•  Step 8 — Save the job
   Scroll to the bottom and click Save to store the job configuration.
•  Step 9 — Run the job
   On the job page click Build Now (left panel) to start a new build.
•  Step 10 — Open the console output
   In the Build History area click the newest build (it appears as a # number), then click Console Output to view logs.
•  Step 11 — Verify the output
   In the console output you should see the line:
   Hello Jenkins!
   This confirms the Freestyle job ran successfully.
