11/04/2022, 3:58 PM Copy code
$ ./pants peek :: > peek.stdout 2> peek.stderr
$ wc -l peek.stdout
61755 peek.stdout
$ wc -l peek.stderr
0 peek.stderr
$ # Makes sense, peek emits to stdout
$
$ ./pants peek :: > peek.stdout
$ wc -l peek.stdout
0 peek.stdout
$ wc -l peek.stderr
0 peek.stderr
$ # What? Where did the output go?happy-kitchen-89482

11/04/2022, 6:22 PMAh, thanks. I noticed that peek output went to stderr the other day, just haven’t gotten around to report it yet.

11/04/2022, 6:29 PMI don’t think it goes to stderr so much as it gets swallowed somehow?

11/04/2022, 6:34 PMwell, this gives me no output:

11/04/2022, 6:35 PMYeah but look at my example above where no output at all happens…

11/04/2022, 6:35 PMMm… ok, maybe not exactly the same, but related

11/04/2022, 6:38 PMindeed, I repro your case too, and if I redirect stderr, I get the peek output on stdout properly
