I am looking to do some processing of pylint output, which would be much easier if it were written to a file. I can give pylint an --output or --output-format option, which will write to a file, but I suspect this will not work well with pants' concurrency. Ideally there would be some way I could insert the current execution slot into the file name, like with pytest. But that would require having support for that env variable in pylint and a way to use it.

We do not mention Pylint, but this should work to too https://www.pantsbuild.org/docs/python-linters-and-formatters#bandit-and-flake8-report-files

Good to know, but my output is a bit unexpected-

$ ls dist/lint/pylint/
