Description of problem: The man page for yum lists the --quiet option to disable output, but the option does not fully work when used with the check-update command Version-Release number of selected component (if applicable): 3.4.3-152 How reproducible: 100% Steps to Reproduce: 1. yum --quiet check-update Actual results: outputs a list of packages to be updated Expected results: there should be no output Additional info: The --quiet option is disabling some of the output -- it prevents the "Loaded plugins" from being listed, but does not prevent the list of packages to be updated from being listed. A script may only be interested in the exit status, so check-update should respect the --quiet option by disabling output.
This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
This issue also exists in dnf and Fedora 22.
According to "man yum" you're right - it should not print output at all. "Run without output. Note that you likely also want to use -y." I don't know how the option was originally designed but it makes sense to me to behave as it is. You basically use this option from scripts for parsing the plain output. The real semantic is: "In combination with non-interactive command (list, info, repoquery, ...) it shows just relevant content. It suppress messages notifying about current state or actions of DNF." I am considering this as a feature not a bug. What would be the benefit of using -q instead of `1>/dev/null` In PR [1] documentation of DNF --quiet was extended.
