[seepine]

like output.txt, it has multiple lines of text

install success
compile success
actions ci finish

I try, but failure

        id: log
        run: |

Hi @seepine

You can use the body-path input to specify the path to a comment body.

      - name: Create or update comment
        uses: peter-evans/create-or-update-comment@v3
        with:
          issue-number: ${{ github.event.pull_request.number }}
          body-path: output.txt
