Current Behavior

Trying to redirect the log file output to GitHub Job Summaries.

      - uses: github/super-linter/slim@v6
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          CREATE_LOG_FILE: true
          # /snip
      - if: always()
        run: cat super-linter.log >> $GITHUB_STEP_SUMMARY

But catting the logfile gives a permissions error.

Expected Behavior

I'd expect subsequent steps to have access to the log file that is created.

Super-Linter version

slim-v6.4.1

Relevant log output

Run cat super-linter.log >> $GITHUB_STEP_SUMMARY
  cat super-linter.log >> $GITHUB_STEP_SUMMARY
  shell: /usr/bin/bash -e {0}
cat: super-linter.log: Permission denied
Error: Process completed with exit code 1.

Steps To Reproduce

on github actions
run while creating log file
attempt to read log file after step is complete

Anything else?

Hi @jasonkarns ! This is currently expected and not a bug because we don't create a user within the container image.

This came up in the past (#1861), so it might be a valid request, also considering that is a recommended best practice.

Feel free to send a PR to implement this, we'll happily review it.
