From db86ea9bcadd58197db54da7a9b7c3d5e5c52cf8 Mon Sep 17 00:00:00 2001 From: Ed Santiago Date: Tue, 15 Sep 2020 14:25:32 -0600 Subject: podman version and --version: fix format, exit Three unrelated fixes to version output: * podman version --format json: was missing a newline * podman version --format TEMPLATE: had too many newlines * podman --version: would neither display version nor exit if followed by a subcommand ('podman --version ps') The first two were easy: I used my best tweezers to delicately pluck and transfer the misplaced \n and place it where needed. The third was a doozy of a rabbit hole. As best I can tell, a workaround was added in root.go to override cobra's built-in Version handling, apparently to avoid having cobra add "-v" as an alias for "--version". As best I can tell, cobra only does this if the "-v" shortcut is not already taken (at least as of Nov 2019: https://github.com/spf13/cobra/pull/996 ). Also as best I can tell that workaround is purely vestigial, and removing it is safe. I've manually tested "-v" in podman run, system df, and rm. I've run system tests.
