# Learning Jenkins, 02-01: Your First Jenkins Job
In this lesson you create your first job.

Use the console to create a freestyle job with one build step.

# MacOS, Linux, and Docker
If you are running Jenkins on MacOS, Linux, or Docker:

1. Select the `Execute shell` build step.
2. Enter the following for the command:
```
echo "Hello, Jenkins"
```

# Troubleshooting Errors
If you select the `Execute Windows batch command` build step, you will see an error similar to the following:
```
Building in workspace /var/jenkins_home/workspace/hello
[hello] $ cmd /c call /tmp/jenkins3248756842772121939.bat

Build step 'Execute Windows batch command' marked build as failure
Finished: FAILURE
```

This is because the program Jenkins uses with the `Execute Windows batch command` build step is not available on your system.

To fix this error, use the `Execute shell` build step as described above.
