official GitHub Actions runner GITHUB_OUTPUT duplicate output names last value environment file parsing

💡 Result:

<search_synthesis>
When multiple lines defining the same output key are written to the GITHUB_OUTPUT environment file within a single step, the GitHub Actions runner processes these lines sequentially, and the final value of that output key will be the last one defined [1][2]. The GITHUB_OUTPUT file operates as a simple append-only log for workflow commands during the execution of a step [3][4][1]. The runner parses this file after the step completes to populate the step&#39;s outputs [5][4]. Because the parser processes the file from top to bottom, subsequent definitions for the same key will overwrite the values of any previous definitions for that same key [1][2]. Key technical considerations include: 1. Consistency: Always use the append operator (>>) when writing to GITHUB_OUTPUT to ensure you are adding to the file rather than overwriting its entire contents, which would result in losing all previously defined outputs for that step [1]. 2. Parsing Logic: While the runner only interprets the first &#39;=&#39; as the key-value separator (allowing values to contain additional &#39;=&#39; signs) [1], duplicating the key itself simply results in the last-written value being the one made available in the steps.<id>.outputs context [1][2]. 3. Step Isolation: Remember that GITHUB_OUTPUT files are unique to each step [5][6]. If you are encountering unexpected behavior where you cannot find an output, ensure you are referencing the correct step ID [7] and that the step has actually executed [7]. To avoid confusion or bugs related to output values, it is best practice to define each unique output key exactly once per step [7]. If you need to produce multiple values or conditional outputs, consider using separate steps or logic within your script to generate a single, final value before writing it to the environment file [7][2].

<title>How to Fix &`#39`;Error: Unable to process file command &`#39`;output&`#39`; successfully&`#39`; in GitHub Actions: Replacing Deprecated set-output with GITHUB_OUTPUT for Multiline Values — codestudy.net</title> https://www.codestudy.net/blog/how-to-fix-or-avoid-error-unable-to-process-file-command-output-successfully/ To address these issues, GitHub introduced the`GITHUB_OUTPUT` file. This file is automatically managed by the GitHub Actions runner and is accessible via the environment variable`$GITHUB_OUTPUT`. ... Instead of printing commands to`stdout`, steps now write outputs directly to the`GITHUB_OUTPUT` file in a simple`key=value` format. This approach is: ... To define an output, write a line in the format`key=value` to`$GITHUB_OUTPUT`. For example: ... echo "my_output=Hello, World!" "$ ... The operator appends the line to the file (use only if overwriting all previous outputs in the step). ... Multiline values (e.g., code blocks, lists, or formatted text) were notoriously tricky with`set-output`.`GITHUB_OUTPUT` simplifies this using a heredoc-style syntax to define values with newlines. ... To handle multiline values with`GITHUB_OUTPUT`, use the syntax: ... ``` echo "key<<DELIMITER" "$GITHUB_OUTPUT" echo "value_line_1" "$GITHUB_OUTPUT" echo "value_line_2" "$GITHUB_OUTPUT" echo "DELIMITER" "$GITHUB_OUTPUT" ``` ... Here,`DELIMITER` is a unique string (e.g.,`EOF`,`END_MULTILINE`) that marks the end of the value. ... Problem: Using(overwrite) instead of(append) erases previous outputs in the same step. Fix: Always use to append to`GITHUB_OUTPUT`: ... ``` # Bad: Overwrites the file (loses previous outputs) echo "key1=value1" "$GITHUB_OUTPUT" # Good: Appends to the file (preserves previous outputs) echo "key1=value1" "$GITHUB_OUTPUT" echo "key2=value2" "$GITHUB_OUTPUT" ``` ... Problem: The delimiter (e.g.,`EOF`) appears in the multiline value, causing the runner to truncate the output early. Fix: Use a unique delimiter (e.g.,`MY_UNIQUE_DELIMITER_123`): ... ``` echo "log<<MY_UNIQUE_DELIMITER_123" "$GITHUB_OUTPUT" echo "This output contains EOF but not MY_UNIQUE_DELIMITER_123" "$GITHUB_OUTPUT" echo "MY_UNIQUE_DELIMITER_123" "$GITHUB_OUTPUT" ... ### Issue 3: Special Characters Breaking key ... value Format# ... Problem: Values with`=`(equals signs) cause parsing issues (e.g.,`key=foo=bar` is interpreted as`key=foo` and`bar` as invalid syntax). Fix:`GITHUB_OUTPUT` automatically handles this! The runner parses only the first`=` as the key-value separator. For`key=foo=bar`, the output will be`key: "foo=bar"`. <title>Duplicated output capture on the latest (1.2.3) version.</title> GitHub issue 397 in appleboy/ssh-action (link omitted to avoid creating a cross-reference) # Duplicated output capture on the latest (1.2.3) version. - State: closed - Author: complynx - Created: 2025-12-04T11:05:05Z - Updated: 2026-01-28T07:58:23Z - Repository: appleboy/ssh-action - Number: `#397` - Assignees: appleboy ## Labels - bug --- ## Describe the bug I&`#39`;m using capture_stdout, and prior to 1.2.3, it was captured only once, but latest duplicates output. ## Yaml Config ```yaml jobs: run-script: runs-on: ubuntu-latest outputs: stdout: ${{ steps.set-output.outputs.stdout }} steps: - name: Run script on complynx.net id: run-script uses: appleboy/ssh-action@v1.2.2 env: ... with: host: complynx.net username: complynx key: ${{ secrets.SERVER_SSH_KEY }} capture_stdout: ${{ inputs.capture_stdout }} command_timeout: 60m envs: > ... script: ${{ inputs.script }} - name: Set output if: ${{ inputs.capture_stdout }} run: | echo "${{ steps.run-script.outputs.stdout }}"|grep -v &`#39`;output: &`#39`; output_filtered=$(echo "${{ steps.run-script.outputs.stdout }}" | grep &`#39`;output: &`#39`; | sed &`#39`;s/^output: //&`#39`;) echo "stdout=$output_filtered" >> $GITHUB_OUTPUT id: set-output ``` latest: 1.2.2: ## Timeline - appleboy was assigned - complynx added label "bug" **appleboy** commented on 2025-12-05T01:53:17Z: > `@complynx` Please help to try v1 or v1.2.4 (latest version) > > > > https://github.com/appleboy/ssh-action/actions/runs/19767607937/job/56644140125 - complynx mentioned - complynx subscribed **complynx** commented on 2025-12-05T18:32:42Z: > Checked right now, seems to work again. - complynx closed **complynx** commented on 2025-12-09T09:33:37Z: > Once again, got the same issue on the latest. 1.2.2 again worked fine. - complynx reopened **appleboy** commented on 2025-12-09T09:59:36Z: > I will take it. - dominikhajduk subscribed **mathieutu** commented on 2026-01-06T14:39:29Z: > Also `@appleboy`, would it be possible to remove the > ``` > =============================================== > ✅ Successfully executed commands to all hosts. > =============================================== > ``` > > message when capturing output? > > If the option is set, it&`#39`;s probably to reuse the stdout in another step, so having this message is just noise to handle. > > Thanks for your amazing work! - appleboy mentioned - appleboy subscribed - Referenced by PR `#403`: fix: prevent stdout duplication when capture_stdout is enabled **cyril23** commented on 2026-01-24T23:09:40Z: > I&`#39`;ve identified the root cause and submitted a fix in PR `#403`. > > **Root cause:** The bug was introduced in PR `#374` (commit b6690ee) during a refactoring.

As a result two new files and environment variables containing their paths are available (`GITHUB_STATE` and `GITHUB_OUTPUT`). These file commands expect a `{name}={value}` format and they support heredoc syntax for multiline strings. An example of a valid file (would work for both `save-state` and `set-output`): ``` MY_NAME=MY_VALUE MY_NAME2=<<EOF this is a multiline string EOF ``` Changes to [toolkit](https://github.com/actions/toolkit) to add support for these coming shortly. ### Saving state for an action using the file command ```bash $ echo "color=yellow" >> $GITHUB_STATE ``` This will make the `STATE_color` environment variable available in all following steps, only for the action that saved that state. ### Setting an output from within a step ```bash $ echo "fruit=banana" >> $GITHUB_OUTPUT ``` Note: all steps setting an output should have an ID set for the output to be retrievable later on. --- ### Timeline **Francesco Renzi** pushed commit `0bb298b`: Add save-state file command · Sep 12, 2022 at 12:12pm **Francesco Renzi** pushed commit `7490f6e`: Add set-output file command · Sep 12, 2022 at 12:34pm **Francesco Renzi** pushed commit `0ac3c43`: Add support for heredoc syntax to save-state file command · Sep 12, 2022 at 4:27pm **Francesco Renzi** pushed commit `f5dc44d`: Add support for heredoc syntax to set-output file command · Sep 12, 2022 at 4:55pm **Francesco Renzi** pushed commit `f7652c9`: Fix copy pasta mistakes in tests · Sep 12, 2022 at 5:01pm **thboop** reviewed: commented · Sep 12, 2022 at 5:50pm **Francesco Renzi** pushed commit `55d63f1`: Refactor reading env files · Sep 13, 2022 at 10:03am **rentziass** marked this as ready for review; requested review from team **actions-runtime** · Sep 13, 2022 at 10:39am **rentziass** mentioned this in PR [`#1178`: Add save-state and set-output file commands](https://github.com/actions/toolkit/pull/1178) · Sep 13, 2022 at 4:58pm **thboop** reviewed: commented · Sep 13, 2022 at 7:15pm **thboop** reviewed: commented · Sep 13, 2022 at 7:16pm **`@thboop`** commented · Sep 13, 2022 at 7:20pm > **Review (commented):** > Left a few nit thoughts! **Francesco Renzi** pushed commit `67d66d7`: Move try/catch into EnvfileKeyValuePairs · Sep 14, 2022 at 9:28am **ChristopherHX** mentioned this in issue [`#1347`: Issue with `-n` dry run](https://github.com/nektos/act/issues/1347) · Sep 15, 2022 at 4pm **thboop** reviewed: commented · Sep 19, 2022 at 7:09pm **`@thboop`** commented · Sep 22, 2022 at 6:18pm > **Review (approved):** > lgtm **rentziass** merged this pull request; closed this; deleted the branch · Sep 26, 2022 at 9:17am **GMNGeoffrey** mentioned this in issue [`#10547`: Adopt GitHub runner output files instead of weird echo commands by 2023-05-31](https://github.com/iree-org/iree/issues/10547) · Sep 26, 2022 at 6:45pm **rlespinasse** mentioned this in PR [`#42`: fix(test): set hard version of core to avoid issue with setoutput](https://github.com/sfeir-open-source/sfeir-school-github-action-dev/pull/42) · Oct 4, 2022 at 12:04pm **rlespinasse** mentioned this in issue [`#45`: Update toolkit/core to latest version](https://github.com/sfeir-open-source/sfeir-school-github-action-dev/issues/45) · Oct 5, 2022 at 9:45pm <title>Search code, repositories, users, issues, pull requests...</title> https://github.com/github/docs/blob/main/content/actions/writing-workflows/choosing-what-your-workflow-does/workflow-commands-for-github-actions.md Actions can communicate with the runner machine to set environment variables, output values used by other actions, add debug messages to the output logs, and other tasks.

<search_synthesis>
GitHub Actions handles process lifecycle and GITHUB_TOKEN permissions according to specific security and operational designs. Process Tree Cleanup and Orphans The GitHub Actions runner manages job termination by tracking processes to ensure clean exits [1][2]. When a job completes or is cancelled, the runner attempts to terminate all child processes and the entire process tree associated with the job [1]. - Tracking Mechanism: The runner identifies processes to terminate by monitoring the RUNNER_TRACKING_ID environment variable [2]. Processes that inherit this variable are considered part of the job&#39;s process tree [2]. - Bypass: Historically, some users have bypassed this cleanup by clearing the RUNNER_TRACKING_ID variable before starting a background process (e.g., export RUNNER_TRACKING_ID=""), though this behavior is not officially supported and may be unreliable across different runner OS environments [2][3]. - Termination Signals: Upon job cancellation, the runner typically sends signals (e.g., SIGINT, followed by SIGTERM, and finally SIGKILL) to the top-level process of a step [1]. Since signals do not automatically propagate down process trees in all environments, child processes may not receive these signals unless the top-level process explicitly forwards them [1]. GITHUB_TOKEN and Fork Pull Requests The GITHUB_TOKEN is a unique, short-lived authentication token created for each workflow job [4]. Its permissions and behavior change significantly when a workflow is triggered by a pull request from a fork [5][6]. - Security Restriction: To prevent unauthorized code from mutating a repository, GitHub automatically downgrades the GITHUB_TOKEN to read-only for pull requests originating from forks [5][6][7]. This occurs regardless of the permissions defined in the workflow file or the repository settings [5][7]. - Write Access: Because of this read-only restriction, any write operations—such as adding comments, creating labels, or pushing commits—will fail with a 403 error (Resource not accessible by integration) [6][7]. - Recommended Workarounds: To perform actions requiring write permissions for fork-based contributions, organizations often use: - workflow_run triggers: A separate, trusted workflow configured to run on the base repository after the main CI workflow completes [6][7]. - pull_request_target: This trigger runs in the context of the base repository and has access to secrets and a writable token [6][7]. It must be used with extreme caution to avoid checking out and executing untrusted PR code, which could lead to security vulnerabilities [6][7].

<title>ringerc/github-actions-signal-handling-demo</title> https://github.com/ringerc/github-actions-signal-handling-demo **TL;DR**: unless special care is taken, child processes don&`#39`;t get any signal delivered to them before they&`#39`;re hard-destroyed when a github actions job is cancelled. As a workaround, `if: always()` blocks can be used to do necessary cleanup steps as they run on cancel. Or for simple cases you can `exec` your process, so it becomes the top-level process for a step and does receive signals on cancel. ... * [`cancel-test-exec-child-ignore ... sigquit.yaml`](.github/workflows/cancel-test-exec-child-ignore-sigquit ... `exec ... script](./signaller.py) that ignores ` ...

It then runs any `if: always()` steps after destroying all processes running in the killed step ... * [`cancel-test-exec-child.yaml`](.github/workflows/cancel-test-exec-child.yaml): `exec`&`#39`;s the same script, but only ignores `SIGINT`, so the child process will terminate on the subsequent `SIGTERM`. This is more realistic, and the subsequent test cases do the same thing. Since it checks the process tree in the `if: always()` cleanup step, this test also shows that github destroys all processes under the step recursively before it begins any cleanup steps. It must be keeping track of all processes. * [`cancel-test-shell-plain.yaml`](.github/workflows/cancel-test-shell-plain.yaml): Represents the "normal" case of a github actions step using a bash shell that runs a child process as a blocking command within the shell. You will see that the child process (the same script as the above demo) *does not* receive any `SIGINT` or `SIGTERM`. The bash leader process does, but you can&`#39`;t see that because bash defers `trap` execution until child process exit when blocking waiting for a child process, and the whole lot gets `SIGKILL`&`#39`;d before the child process exits to return control to bash. This means that the workload running in the inner script got no chance to clean up its work. ... * [`cancel-test-shell-sigfwd.yaml`](.github/workflows/cancel-test-shell-sigfwd.yaml): Demonstrates that it is possible to use a top-level shell with job control enabled as a process-group leader that forwards signals to its child processes. It&`#39`;s *ugly* though. Because of deferred traps, every subcommand that needs a chance to handle signals must be run as a background job with `&` then `wait`ed for, and there&`#39`;s plenty of fiddling about to make it work. See comments in [`signal_forwarding_wrapper.sh`](./signal_forwarding_wrapper.sh) for details. ... end of the containing ... everything running under a ... run after cancellation of ... **On cancel, github actions delivers a `SIGINT` only to the top-level process for the current step of each active job**. Then 7.5s later it delivers a `SIGTERM`, again to the top-level process only. 2.5s later it sends a `SIGKILL` (presumably to everything in the process tree). You&`#39`;d think that&`#39`;s fine. But **signals don&`#39`;t propagate down process trees**, so child processes running under the top-level step process won&`#39`;t see a signal unless the top-level process explicit forwards it. ... A typical Github actions job will be a `run` step with `shell: bash` that invokes some task as a child process of the step&`#39`;s top-level shell.

Any process with this variable set is treated as a child of the runner and will be stopped. Note On GitHub-hosted runners, this is usually not a concern since the entire virtual machine is discarded after the job ends. To keep a process running after the job completes, start it without the `RUNNER_TRACKING_ID` environment variable.

You can use the `GITHUB_TOKEN` to authenticate in the workflow job. When you enable GitHub Actions, GitHub installs a GitHub App on your repository. The `GITHUB_TOKEN` secret is a GitHub App installation access token. You can use the installation access token to authenticate on behalf of the GitHub App installed on your repository. The token&`#39`;s permissions are limited to the repository that contains your workflow. For more information, see Workflow syntax for GitHub Actions. Before each job begins, GitHub fetches an installation access token for the job. The `GITHUB_TOKEN` expires when the job finishes or after its effective maximum lifetime. The effective maximum lifetime of the token depends on the type of runner: - GitHub-hosted runners The maximum job execution time is 6 hours, so the `GITHUB_TOKEN` can live for a maximum of 6 hours. - Self-hosted runners The maximum job execution time is 5 days. However, because the `GITHUB_TOKEN` is an installation access token, it can only be refreshed for up to 24 hours. If your job runs longer than 24 hours, use a personal access token or other authentication method instead. The token is also available in the `github.token` context. For more information, see Contexts reference. ## When `GITHUB_TOKEN` triggers workflow runs When you use the repository&`#39`;s `GITHUB_TOKEN` to perform tasks, events triggered by the `GITHUB_TOKEN` will not create a new workflow run, with the following exceptions: - `workflow_dispatch` and `repository_dispatch` events always create workflow runs. - `pull_request` events with the `opened`, `synchronize`, or `reopened` activity types: when a workflow using `GITHUB_TOKEN` creates or updates a pull request, the resulting `pull_request` event creates workflow runs in an approval-required state. The pull request displays a banner in the merge box, and a user with write access to the repository can start the runs by selecting Approve workflows to run. Other `pull_request` activity types (such as `labeled`, `edited`, or `closed`) do not create workflow runs. This prevents recursive workflow runs while still allowing CI workflows to run on pull requests created by automation. For more information about approving workflow runs, see Approving workflow runs from forks. For all other events, this behavior prevents you from accidentally creating recursive workflow runs. For example, if a workflow run pushes code using the repository&`#39`;s `GITHUB_TOKEN`, a new workflow will not run even when the repository contains a workflow configured to run when `push` events occur. > [!NOTE] > If you need workflow runs from workflow-created pull requests to execute without requiring approval, use a GitHub App installation access token or a personal access token instead of `GITHUB_TOKEN` when creating or updating the pull request. Commits pushed by a GitHub Actions workflow that uses the `GITHUB_TOKEN` do not trigger a GitHub Pages build. ## Next steps - Use GITHUB_TOKEN for authentication in workflows - Workflow syntax for GitHub Actions <title>GitHub Actions permissions: Every Scope</title> https://latchkey.dev/learn/github-actions/github-actions-permissions-reference GitHub Actions permissions: Every Scope # GitHub Actions permissions: Every Scope and What Needs It By Kaveh Alemi· Latchkey Declaring a `permissions:` block replaces the defaults entirely rather than adding to them, so an incomplete block breaks steps that worked yesterday. The `GITHUB_TOKEN` is minted per job with a permission set. It comes from repository or organisation defaults unless the workflow declares its own, and the moment it does, the declaration is the complete set. That replacement behaviour is the single most common cause of a permissions failure appearing right after someone tightened security: the block lists the scope they were thinking about and silently drops the ones that were previously default. ## Every scope | Scope | Grants | Needed for | | --- | --- | --- | | `actions` | Workflows and runs | Cancelling runs, reading artifacts via API | | `attestations` | Artifact attestations | Provenance and supply-chain attestation | | `checks` | Check runs and suites | Publishing test results as checks | | `contents` | Repository contents | Checkout, pushing commits, creating releases | | `deployments` | Deployments | Creating deployment records | | `discussions` | Discussions | Commenting on discussions | | `id-token` | OIDC token | Cloud auth via OIDC. Must be `write` | | `issues` | Issues | Creating, labelling, commenting on issues | | `packages` | GitHub Packages | Pushing to GHCR | | `pages` | GitHub Pages | Deploying Pages | | `pull-requests` | Pull requests | Commenting, labelling, requesting review | | `repository-projects` | Projects | Updating project boards | | `security-events` | Code scanning | Uploading SARIF results | | `statuses` | Commit statuses | Setting commit status | Each is `read`, `write`, or `none`. Shorthand `permissions: read-all` and `write-all` set every scope, and `permissions: {}` removes all of them. Latchkey runs these workflows on managed runners at $0.0025/min against the $0.006 GitHub-hosted rate, and repairs transient failures automatically. ## The replacement rule .github/workflows/ci.yml ``` # Before: repository defaults, whatever they are # (no permissions block) # After: contents is the ONLY permission this job has. # A step that used to comment on a PR now fails with 403. permissions: contents: read # Correct: list everything the job needs permissions: contents: read pull-requests: write checks: write ``` Declare permissions at the job level rather than the workflow level where you can. A workflow-level grant applies to every job, including ones that only run tests and should not hold write scopes. ## What no permissions block can grant - Fork pull requests. A `pull_request` event from a fork gets a read-only token and no access to secrets, by design and regardless of any `permissions:` declaration. - Cross-repository access.`GITHUB_TOKEN` is scoped to the repository running the workflow. Another repository needs a PAT or a GitHub App token. - Anything above the repository or organisation default. If the default is restricted to read, a workflow cannot grant itself write. - Triggering another workflow. Events created using `GITHUB_TOKEN` do not start new workflow runs, which is a loop-prevention rule rather than a permission. ## Common combinations .github/workflows/ci.yml ``` # push a container image to GHCR permissions: contents: read packages: write # authenticate to a cloud provider with OIDC permissions: contents: read id-token: write # comment on a PR and publish check results permissions: contents: read pull-requests: write checks: write # upload code scanning results permissions: contents: read security-events: write ``` ## Diagnose it: what token do you actually have? Permission failures in Actions are almost never about your repository settings alone. Three things combine: the default `GITHUB_TOKEN` permission set for the repo or organization, the `permissions:` block in the workflow, and whether the event is a fork pull request, which downgrades the token to...

Keep failure_reason out of JavaScript source.

The direct pytest process exits before the checker writes its literal. However, PR-controlled test code can start a descendant that inherits GITHUB_OUTPUT and appends after _write_github_output() while the step is still running. GitHub Actions uses the last duplicate output value. The workflow then inserts that value into a JavaScript template literal, where backticks and statements can alter the github-script source. Fork pull requests receive a read-only token, but this does not make the interpolation safe.

Pass the value through the environment:

Handle other_failure without waiver guidance.

.github/scripts/check_all_skip.py writes failure_reason=other_failure for zero-collected and setup/teardown failures when no unwaived all-skip violation exists. This else branch treats that value, and an empty output, as an all-skip result. Authors then receive waiver instructions for failures that a waiver cannot resolve. Branch explicitly on reason === 'all_skip' and use a generic failure message otherwise.
