Red Hat Bugzilla 1358245 0 low CLOSED repoquery: valid use of stderr and stdout, use stdout only for requested data 2023-02-23 11:13:09 UTC

Description Zbigniew Jędrzejewski-Szmek 2023-02-23 11:13:10 UTC
Description of problem:
Program logs and error messages must be written to fd 2 (i.e. stderr), and the actual output to fd 1 (i.e. stdout). Doing anything else makes it very hard to use the program in a pipeline. dnf5 repoquery writes log messages to stdout.

$ dnf5 repoquery 2>/dev/null | grep Repositories
Repositories loaded.

"Repositories loaded." is obviously not a package name.
