How to Create a Jenkins Job that Reads and Prints Environment Variables During a Build?| S-Logix

Description:
Jenkins automatically provides several environment variables during a build, such as $JENKINS_HOME, $WORKSPACE, and $BUILD_NUMBER. These variables help you identify the Jenkins home directory, the job workspace, and the build number. By printing them in a job, you can verify the environment setup and use these variables in scripts or pipelines.

Step 1 — Open Jenkins Dashboard
Go to your browser and enter your Jenkins URL, e.g., http://localhost:8080
Step 2 — Create a New Job
Click New Item on the left menu
Enter Job Name: env-test
Select Freestyle Project → Click OK
Step 3 — Add a Build Step
Scroll to the Build section
Click Add build step → Execute shell

Step 4 — Enter Shell Script
In the shell command box, type:

echo "Jenkins Home: $JENKINS_HOME"
echo "Workspace: $WORKSPACE"
echo "Build Number: $BUILD_NUMBER"

Step 5 — Save the Job
Click Save at the bottom of the configuration page
Step 6 — Run the Job
Click Build Now on the left panel
Jenkins will execute the shell script
Step 7 — View the Build Output
Under Build History, click the latest build → Console Output
You should see something like:
```
Jenkins Home: /var/lib/jenkins
Workspace: /var/lib/jenkins/workspace/env-test
Build Number: 1
Finished: SUCCESS
```
Goal
The job successfully prints key Jenkins environment variables, which can be used for debugging, scripting, or dynamic configuration in builds.
