You can use a **Run** step to run commands or scripts in a CI pipeline. Here are some examples of different ways you can use **Run** steps. {% tabs %} {% tab title="Run tests" %} This example runs `pytest`, includes [code coverage](/continuous-integration/3.0/use-harness-ci/use-harness-ci/run-tests/code-coverage.md), and produces a report in JUnit XML format. ```yaml - step: type: Run name: Run pytest identifier: Run_pytest spec: connectorRef: YOUR_IMAGE_REGISTRY_CONNECTOR image: python:latest shell: Sh command: |- echo "Welcome to Harness CI" uname -a pip install pytest pip install pytest-cov pip install -r requirements.txt pytest -v --cov --junitxml="result.xml" test_api.py test_api_2.py test_api_3.py echo "Done" reports: type: JUnit spec: paths: - "**/*.xml" ``` {% hint style="info" %} In Harness CI, you can [use test splitting (parallelism)](/continuous-integration/3.0/use-harness-ci/use-harness-ci/run-tests/speed-up-ci-test-pipelines-using-parallelism.md) to improve test times for any language or test tool. {% endhint %} {% endtab %} {% tab title="Install dependencies" %} This example installs Go dependencies. ```yaml - step: type: Run identifier: dependencies name: Dependencies spec: shell: Sh command: |- go get example.com/my-go-module ``` {% endtab %} {% tab title="Specify versions" %} This example uses a **Run** step to select a version of Xcode. ```yaml - step: type: Run name: set_xcode_version identifier: set_xcode_version spec: shell: Sh command: |- sudo xcode-select -switch /Applications/Xcode_15.1.0.app xcodebuild -version ``` {% endtab %} {% tab title="Clone a repo" %} This example clones a GitHub repository. ```yaml - step: type: Run identifier: clone name: clone spec: shell: Sh command: |- git clone https://GH_PERSONAL_ACCESS_TOKEN@github.com/ACCOUNT_NAME/REPO_NAME.git ``` To use this command, you would replace: * `ACCOUNT_NAME` with your GitHub account name. * `REPO_NAME` with the name of the GitHub repo to clone. * `PERSONAL_ACCESS_TOKEN` with a [GitHub personal access token](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token) that has pull permissions to the target repository. Additional permissions may be necessary depending on the Action's purpose. Store the token as a [Harness secret](/harness-platform/3.0/harness-platform-resources/secrets.md) and use a variable expression, such as `<+secrets.getValue("YOUR_TOKEN_SECRET")>`, to call it. {% endtab %} {% tab title="Run scripts" %} **Run** steps are highly versatile, and you can use them to run all manner of individual commands or multi-line scripts. For example, this step produces [output variables](#output-variables) from Terraform value. This step is from the [Terraform notifications trigger tutorial](/harness-platform/3.0/harness-platform-resources/triggers/tutorial-terraform-cloud-notification-trigger.md), and these output variables are used by another step later in the same pipeline. ```yaml - step: type: Run name: Terraform Outputs identifier: tf_outputs spec: connectorRef: YOUR_IMAGE_REGISTRY_CONNECTOR image: kameshsampath/kube-dev-tools shell: Sh command: |- cd /harness/vanilla-gke/infra terraform init GCP_PROJECT=$(terraform output -raw project-name) GCP_ZONE=$(terraform output -raw zone) GKE_CLUSTER_NAME=$(terraform output -raw kubernetes-cluster-name) envVariables: TF_TOKEN_app_terraform_io: <+secrets.getValue("terraform_cloud_api_token")> TF_WORKSPACE: <+trigger.payload.workspace_name> TF_CLOUD_ORGANIZATION: <+trigger.payload.organization_name> outputVariables: - name: GCP_PROJECT - name: GCP_ZONE - name: GKE_CLUSTER_NAME imagePullPolicy: Always description: Get the outputs of terraform provision ``` {% hint style="info" %} Consider [creating plugins](/continuous-integration/3.0/use-harness-ci/use-harness-ci/use-drone-plugins/custom-plugins.md) for scripts that you reuse often. {% endhint %} {% endtab %} {% tab title="Connect with SSH" %} This example demonstrates how to set up SSH authentication in a **Run** step, such as when connecting to a private Git server or remote machine. The SSH private key must be stored in Harness as a **File-type Secret** to be used securely in the pipeline. ```yaml - step: type: Run name: SSH setup and build identifier: SSH_Build spec: shell: Sh command: |- mkdir -p ~/.ssh echo '<+secrets.getValue("account.your-ssh-private-key")>' > ~/.ssh/id_rsa chmod 600 ~/.ssh/id_rsa export GIT_SSH_COMMAND="ssh -o StrictHostKeyChecking=no" git clone git@github.com:your-org/private-repo.git ./build.sh ``` {% hint style="info" %} * Replace `account.your-ssh-private-key` with your actual secret reference. * The `StrictHostKeyChecking=no` flag disables host verification. For production pipelines, consider managing known hosts instead. * Ensure your build image has OpenSSH tools (ssh, git, etc.) installed. {% endhint %} {% endtab %} {% tab title="Annotations" %} ```yaml - step: identifier: build_and_test type: Run name: Build and Test spec: connectorRef: my-k8s-connector image: harness/ci-addon:latest shell: Bash command: |- # Step 1: Create markdown content for our reports # A comprehensive build report cat > build-results.md << 'EOF' # ๐Ÿš€ Build Pipeline Results ![Build Status](https://img.shields.io/badge/build-passing-brightgreen.svg) > **Note:** View full build logs [here](https://example.com). ## ๐Ÿงช Test Summary - **Total Tests:** 247 - **Passed:** โœ… **245** - **Failed:** โŒ **2** - **Coverage:** **92.4%** EOF # Step 2: Publish the annotations using hcli # Publish the main build report with a WARNING style and high priority hcli annotate --context "build-validation" --style "warning" --summary-file "build-results.md" --priority 8 # Step 3: Append additional notes to an existing context echo "Flaky tests have been quarantined." > extra-notes.md hcli annotate --context "build-validation" --summary-file "extra-notes.md" --mode "append" ``` {% hint style="info" %} Go to [Pipeline Annotations](https://app.gitbook.com/s/3F2TpHXhur2QtQnORSM9/harness-platform-resources/pipelines/harness-annotations) to learn more about how you could summarize critical pipeline metrics. {% endhint %} {% endtab %} {% endtabs %} ### Add the Run step You need a [CI pipeline](/continuous-integration/3.0/use-harness-ci/use-harness-ci/prep-ci-pipeline-components.md) with a [Build stage](/continuous-integration/3.0/use-harness-ci/use-harness-ci/set-up-build-infrastructure/ci-stage-settings.md) where you'll add the **Run** step. In order for the **Run** step to execute your commands, the build environment must have the necessary binaries for those commands. Depending on the stage's build infrastructure, **Run** steps can use binaries that exist in the build environment or pull an image, such as a public or private Docker image, that contains the required binaries. For more information about when and how to specify images, go to the [Container registry and image settings](#container-registry-and-image). {% tabs %} {% tab title="Visual" %} 1. Go to the **Build** stage in the pipeline where you want to add the **Run** step. 2. On the **Execution** tab, select **Add Step**, and select the **Run** step from the Step Library. 3. Configure the [Run step settings](#run-step-settings) and then select **Apply Changes** to save the step. {% endtab %} {% tab title="YAML" %} In Harness, go to the pipeline where you want to add the `Run` step. In the `CI` stage, add a `Run` step and configure the [Run step settings](#run-step-settings). ```yaml - step: type: Run name: run pytest # Specify a name for the step. identifier: run_pytest # Define a step ID, usually based on the name. spec: connectorRef: YOUR_IMAGE_REGISTRY_CONNECTOR image: python:latest # Specify an image, if required. shell: Sh command: |- # Provide your commands pytest test_main.py --junit-xml=output-test.xml ``` {% endtab %} {% endtabs %} ### Run step settings The CI **Run** step has the following settings. {% hint style="info" %} Depending on the stage's build infrastructure, some settings might be unavailable or optional. Settings specific to containers, such as **Set Container Resources**, are not applicable when using the step in a stage with VM or Harness Cloud build infrastructure. {% endhint %} #### Metadata * **Name:** Enter a name summarizing the step's purpose. Harness automatically assigns an [ID](/harness-platform/3.0/harness-platform-resources/references/entity-identifier-reference.md) based on the **Name**. * **Description:** Optional text string describing the step's purpose. #### Container Registry and Image **Container Registry** and **Image** ensure that the build environment has the binaries necessary to execute the commands that you want to run in this step. For example, a cURL script may require a cURL image, such as `curlimages/curl:7.73.0`.
When are Container Registry and Image required? The stage's build infrastructure determines whether these fields are required or optional: * [Kubernetes cluster build infrastructure](/continuous-integration/3.0/use-harness-ci/use-harness-ci/set-up-build-infrastructure/k8s-build-infrastructure/set-up-a-kubernetes-cluster-build-infrastructure.md): **Container Registry** and **Image** are always required. * [Local runner build infrastructure](/continuous-integration/3.0/use-harness-ci/use-harness-ci/set-up-build-infrastructure/define-a-docker-build-infrastructure.md): **Run** steps can use binaries available on the host machine. The **Container Registry** and **Image** are required if the machine doesn't have the binary you need. * [Self-managed AWS/GCP/Azure VM build infrastructure](/continuous-integration/3.0/use-harness-ci/use-harness-ci/set-up-build-infrastructure/vm-build-infrastructure.md): **Run** steps can use binaries that you've made available on your build VMs. The **Container Registry** and **Image** are required if the VM doesn't have the necessary binaries. These fields are located under **Optional Configuration** for stages that use self-managed VM build infrastructure. * [Harness Cloud build infrastructure](/continuous-integration/3.0/use-harness-ci/use-harness-ci/set-up-build-infrastructure/use-harness-cloud-build-infrastructure.md): **Run** steps can use binaries available on Harness Cloud machines, as described in the [image specifications](/continuous-integration/3.0/use-harness-ci/use-harness-ci/set-up-build-infrastructure/use-harness-cloud-build-infrastructure.md#platforms-and-image-specifications). The **Container Registry** and **Image** are required if the machine doesn't have the binary you need. These fields are located under **Optional Configuration** for stages that use Harness Cloud build infrastructure.
#### Shell and Command Use these fields to define the commands that you need to run in this step. For **Shell**, select the shell type. Options include: **Bash**, **PowerShell**, **Pwsh** (PowerShell Core), **Sh**, and **Python**. If the step includes commands that aren't supported for the selected shell type, the build fails. Required binaries must be available on the build infrastructure or through a specified [Container Registry and Image](#container-registry-and-image). In the **Command** field, enter [POSIX](https://en.wikipedia.org/wiki/POSIX) shell script commands for this step. The script is invoked as if it were the entry point. If the step runs in a container, the commands are executed inside the container. {% tabs %} {% tab title="Bash" %} For Bash, set the `shell` to `Bash` and enter your Bash script in `command`. For example, the following step runs a Bash script that checks the Java version: ```yaml - step: ... spec: shell: Bash command: |- JAVA_VER=$(java -version 2>&1 | head -1 | cut -d'"' -f2 | sed '/^1\./s///' | cut -d'.' -f1) if [[ $JAVA_VER == 17 ]]; then echo successfully installed $JAVA_VER else exit 1 fi ``` {% endtab %} {% tab title="PowerShell" %} For PowerShell, set the `shell` to `Powershell` and enter your PowerShell script in `command`, for example: ```yaml - step: ... spec: shell: Powershell command: Wait-Event -SourceIdentifier "ProcessStarted" ``` {% hint style="info" %} You can run PowerShell commands on Windows VMs running in AWS build farms. {% endhint %} {% endtab %} {% tab title="Pwsh (PowerShell Core)" %} You can run PowerShell Core commands in pods or containers that have `pwsh` installed. For PowerShell Core, set the `shell` to `Pwsh` and enter your PowerShell Core script in `command`. For example, this step runs `ForEach-Object` over a list of events. ```yaml - step: ... spec: shell: Pwsh command: |- $Events = Get-EventLog -LogName System -Newest 1000 $events | ForEach-Object -Begin {Get-Date} -Process {Out-File -FilePath Events.txt -Append -InputObject $_.Message} -End {Get-Date} ``` {% endtab %} {% tab title="Sh" %} You can use the `Sh` option to run any shell script, provided the necessary binaries are available. For example, this step pulls the latest `python` image and then executes a shell script (`Sh`) that runs `pytest` with code coverage. ```yaml - step: ... spec: connectorRef: YOUR_IMAGE_REGISTRY_CONNECTOR image: python:latest shell: Sh command: |- echo "Welcome to Harness CI" uname -a pip install pytest pip install pytest-cov pip install -r requirements.txt pytest -v --cov --junitxml="result.xml" test_api.py test_api_2.py test_api_3.py ``` {% endtab %} {% tab title="Python" %} For Python, set the `shell` to `python` and enter your Python commands in `command`, for example: ```yaml steps: - step: ... spec: shell: Python command: |- print('Hello, world!') ``` {% endtab %} {% endtabs %} **Reference background services** You can reference services started in [Background steps](/continuous-integration/3.0/use-harness-ci/use-harness-ci/manage-dependencies/background-step-settings.md) by using the Background step's **Id** in your Run step's **Command**. For example, a cURL command could call `BackgroundStepId:5000` where it might otherwise call `localhost:5000`. The exact format depends on your build infrastructure. For more information, go to [Background step settings - Name and ID](/continuous-integration/3.0/use-harness-ci/use-harness-ci/manage-dependencies/background-step-settings.md#name-and-id) and [Background step settings - Port Bindings](/continuous-integration/3.0/use-harness-ci/use-harness-ci/manage-dependencies/background-step-settings.md#port-bindings). If the Background step is inside a step group, you must include step group ID, such as `StepGroupId_BackgroundStepId:5000`, even if both steps are in the same step group. **Scripts that produce output variables** If your script produces an output variable, you must declare the output variable in the Run step's [Output Variables](#output-variables). For example, the following step runs a `python` script that defines an output variable called `OS_VAR`, and `OS_VAR` is also declared in the `outputVariables`. ```yaml - step: type: Run name: Run_2 identifier: Run_2 spec: shell: Python command: |- import os os.environ["OS_VAR"] = value outputVariables: - name: OS_VAR ``` **Images without a shell** To support Docker images without a shell, the **Command** field is optional. You must provide either **Image**, **Command**, or both. If you provide only **Image**, Harness runs the image entrypoint. If **Command** is empty or omitted, then Harness ignores **Shell**. The default value for **Shell** is `Sh`; however the presence of **Shell** doesn't require **Command**. #### Report Paths If relevant to the commands in your Run step, you can specify one or more paths to files that store [test results in JUnit XML format](/continuous-integration/3.0/use-harness-ci/use-harness-ci/run-tests/test-report-ref.md). You can add multiple paths. If you specify multiple paths, make sure the files contain unique tests to avoid duplicates. [Glob](https://en.wikipedia.org/wiki/Glob_\(programming\)) is supported. This setting is required for the Run step to be able to [publish test results](/continuous-integration/3.0/use-harness-ci/use-harness-ci/run-tests/viewing-tests.md). For example, this step runs `pytest` and produces a test report in JUnit XML format. ```yaml - step: type: Run name: Pytest identifier: Pytest spec: shell: Sh command: |- pytest test_main.py --junit-xml=output-test.xml reports: type: JUnit spec: paths: - output-test.xml ``` #### Environment Variables You can inject environment variables into the step container and use them in the commands executed in this step. You must input a **Name** and **Value** for each variable. You can reference environment variables by name in commands. For example, a Bash script would use `$var_name` or `${var_name}`, and a Windows PowerShell script would use `$Env:varName`. Variable values can be [fixed values, runtime inputs, or expressions](/harness-platform/3.0/harness-platform-resources/variables-and-expressions/runtime-inputs.md). For example, if the value type is expression, you can input a value that references the value of some other setting in the stage or pipeline. {% hint style="info" %} **STAGE VARIABLES** [Stage variables](/harness-platform/3.0/harness-platform-resources/overview/overview.md) are inherently available to steps as environment variables. {% endhint %} #### Output Variables **Scoping output variables using aliases** To prevent variable name conflicts, you can use **Publish Variable Names (Alias)** to scope output variables to different entities. 1. **Export the variables:** Use **Output Variables** to export the variables. 2. **Define an alias:** In **Publish Variable Names (Alias)**, enter an alias to use to reference the exported output variables. 3. **Select a scope:** In **Scope**, select the scope for the exported output variable. The following screenshot shows the output alias configured with **Stage** scope: The following screenshot shows the output alias configured with **Pipeline** scope: You can scope output variables to the following entities: * **Step group:** * The output variable must be used in the same step group, including nested child step groups. * The format for referencing an exported step group output variable using its alias is: ``` <+exportedVariables.getValue("stepGroup.ALIAS_NAME.OUTPUT_VARIABLE_NAME")> ``` * **Stage:** * The output variable can be used anywhere in the same stage, including step groups in the same stage. It cannot be used outside of the same stage. * The format for referencing an exported stage output variable using its alias is: ``` <+exportedVariables.getValue("stage.ALIAS_NAME.OUTPUT_VARIABLE_NAME")> ``` * **Pipeline:** * The output variable can be used anywhere in the same pipeline but not in a [chained pipeline](/harness-platform/3.0/harness-platform-resources/overview/overview/blank-canvas/chained-pipeline.md). * The format for referencing an exported pipeline output variable using its alias is: ``` <+exportedVariables.getValue("pipeline.ALIAS_NAME.OUTPUT_VARIABLE_NAME")> ``` To reference a map of exported output variables, reference the alias in the format `<+exportedVariables.getValue("SCOPE.ALIAS_NAME")>`, like `<+exportedVariables.getValue("stepGroup.info")>`. {% hint style="info" %} **IMPORTANT NOTES** * Exported variables are immutable. * Variables cannot be exported in looping strategies. * Exported variables are not supported in pipeline chaining. * All output variables are exported. You cannot select a subset. {% endhint %}

For more information, go to [Scoping output variables using aliases](/continuous-delivery/use-continuous-delivery/cd-building-blocks/cd-steps/utilities/shell-script-step.md#scoping-output-variables-using-aliases) in the Shell Script step documentation. #### Additional container settings Settings specific to containers are not applicable in a stages that use VM or Harness Cloud build infrastructure. **Privileged** Enable this option to run the container with escalated privileges. This is equivalent to running a container with the Docker `--privileged` flag. **Image Pull Policy** If you specified a [Container Registry and Image](#container-registry-and-image), you can specify an image pull policy: * **Always**: The kubelet queries the container image registry to resolve the name to an image digest every time the kubelet launches a container. If the kubelet encounters an exact digest cached locally, it uses its cached image; otherwise, the kubelet downloads (pulls) the image with the resolved digest, and uses that image to launch the container. * **If Not Present**: The image is pulled only if it is not already present locally. * **Never**: The image is assumed to exist locally. No attempt is made to pull the image. **Run as User** If you specified a [Container Registry and Image](#container-registry-and-image), you can specify the user ID to use for running processes in containerized steps. For a Kubernetes cluster build infrastructure, the step uses this user ID to run all processes in the pod. For more information, go to [Set the security context for a pod](https://kubernetes.io/docs/tasks/configure-pod-container/security-context/#set-the-security-context-for-a-pod). **Set Container Resources** Maximum resources limits for the resources used by the container at runtime: * **Limit Memory:** Maximum memory that the container can use. You can express memory as a plain integer or as a fixed-point number with the suffixes `G` or `M`. You can also use the power-of-two equivalents, `Gi` or `Mi`. Do not include spaces when entering a fixed value. The default is `500Mi`. * **Limit CPU:** The maximum number of cores that the container can use. CPU limits are measured in CPU units. Fractional requests are allowed. For example, you can specify one hundred millicpu as `0.1` or `100m`. The default is `400m`. For more information, go to [Resource units in Kubernetes](https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/#resource-units-in-kubernetes). #### Timeout Set the timeout limit for the step. Once the timeout limit is reached, the step fails and pipeline execution continues. To set skip conditions or failure handling for steps, go to: * [Step Skip Condition settings](/harness-platform/3.0/harness-platform-resources/overview/strategy/conditional-execution.md) * [Step Failure Strategy settings](/harness-platform/3.0/harness-platform-resources/overview/strategy/on-failure.md) ### Run step logs and test results During and after pipeline runs, you can find step logs on the [Build details page](/continuous-integration/3.0/use-harness-ci/use-harness-ci/viewing-builds.md). If your pipeline runs tests, you can [view test reports](/continuous-integration/3.0/use-harness-ci/use-harness-ci/run-tests/viewing-tests.md) on the Build details page. ### Run step and Pipeline Annotations Pipeline Annotations allow you to publish rich, structured insights directly into the Harness pipeline execution page. Instead of sifting through thousands of lines of logs to find critical information like test summaries, security scan results, or deployment notes, you can use the `hcli annotate` command to push this data to a dedicated **Annotations** tab in the Harness UI. For more information visit [Pipeline Annotations](https://app.gitbook.com/s/3F2TpHXhur2QtQnORSM9/harness-platform-resources/pipelines/harness-annotations) ### Hidden/Invisible Characters Customers may occasionally encounter unexplained behavior in their scripts caused by hidden or invisible characters. These characters often appear when copying and pasting from non-plain-text sources and can lead to unexpected script errors. Harness includes a feature to display invisible characters, which is enabled by default. When invisible characters are present, users will see a highlighted space in their scripts. They can hover over the highlight to view the character and click "Adjust settings" to manage the display. If a selection was accidentally made, the user can right-click within the script area and open the **Command Palette**. A dialog box will appear, allowing the user to search for and toggle the setting that controls how invisible characters are highlighted. ### Troubleshoot script execution (Run steps) Go to the [CI Knowledge Base](/continuous-integration/3.0/troubleshooting-and-resources/ci-articles-and-faqs/continuous-integration-faqs.md) for questions and issues related to script execution and using Run steps, such as: * [Can I use an image that doesn't have a shell in a Run step?](/continuous-integration/3.0/troubleshooting-and-resources/ci-articles-and-faqs/continuous-integration-faqs.md#can-i-use-an-image-that-doesnt-have-a-shell-in-a-run-step) * [Is a Docker image required to use the Run step on local runner build infrastructure?](/continuous-integration/3.0/troubleshooting-and-resources/ci-articles-and-faqs/continuous-integration-faqs.md#is-a-docker-image-required-to-use-the-run-step-on-local-runner-build-infrastructure) * [When attempting to export an output variable from a Run step using a Python shell, the step fails with "no such file or directory"](/continuous-integration/3.0/troubleshooting-and-resources/ci-articles-and-faqs/continuous-integration-faqs.md#when-attempting-to-export-an-output-variable-from-a-run-step-using-a-python-shell-the-step-fails-with-no-such-file-or-directory) * [What does the "Failed to get image entrypoint" error indicate in a Kubernetes cluster build?](/continuous-integration/3.0/troubleshooting-and-resources/ci-articles-and-faqs/continuous-integration-faqs.md#what-does-the-failed-to-get-image-entrypoint-error-indicate-in-a-kubernetes-cluster-build) * [Does the Harness Run step overwrite the base image container entry point?](/continuous-integration/3.0/troubleshooting-and-resources/ci-articles-and-faqs/continuous-integration-faqs.md#does-the-harness-run-step-overwrite-the-base-image-container-entry-point) * [Why is the default entry point not running for the container image used in the Run step?](/continuous-integration/3.0/troubleshooting-and-resources/ci-articles-and-faqs/continuous-integration-faqs.md#why-is-the-default-entry-point-not-running-for-the-container-image-used-in-the-run-step) * [How do I start a service started in a container that would usually be started by the default entry point?](/continuous-integration/3.0/troubleshooting-and-resources/ci-articles-and-faqs/continuous-integration-faqs.md#since-the-default-entry-point-isnt-executed-for-the-container-image-used-in-the-run-step-how-do-i-start-a-service-started-in-a-container-that-would-usually-be-started-by-the-default-entry-point) * [How do I run the default entry point of the image used in the Run step?](/continuous-integration/3.0/troubleshooting-and-resources/ci-articles-and-faqs/continuous-integration-faqs.md#how-do-i-run-the-default-entry-point-of-the-image-used-in-the-run-step) * [Does CI support running Docker-in-Docker images?](/continuous-integration/3.0/troubleshooting-and-resources/ci-articles-and-faqs/continuous-integration-faqs.md#does-ci-support-running-docker-in-docker-images) * [Can't connect to Docker daemon with Docker-in-Docker Background step.](/continuous-integration/3.0/troubleshooting-and-resources/ci-articles-and-faqs/continuous-integration-faqs.md#cant-connect-to-docker-daemon) * [Concatenated variable values in PowerShell scripts print to multiple lines](/continuous-integration/3.0/troubleshooting-and-resources/ci-articles-and-faqs/continuous-integration-faqs.md#concatenated-variable-values-in-powershell-scripts-print-to-multiple-lines) {% @harness-feedback/feedback %}
