Conceptually simple: include, where applicable, a brief
description of command-line options for each subcommand.

Hi @edsantiago. Thanks for your PR.

I'm waiting for a containers or openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

VERY LOW PRIORITY. And I realize of course that I'll need to rebase after (if) #2452 is merged.

I also realize it'll be tedious to review. I'm sorry. Possible suggestions:

$ git log -1 -p | egrep '^\+\s' |less
[shows a brief summary of each added line]

$ egrep -r 'Use: *"[a-z]+"' cmd/podman
[shows the ones I omitted or missed.]
FIXME: I'd like suggestions for 'trust'

@baude PTAL but again very low priority

[edsantiago]

CI failure: gating: because I added DisableFlagsInUseLine (to avoid a misleading addition of "[flags]" to the use string). Someone isn't happy with the indentation. Should I update that in init instead?

@edsantiago i think this looks great... given it is outward facing, would like thumb up from @rhatdan and @mheon . i pulled the PR and really like how it looks. Adding example for the fellas here:

sudo podman attach --help
The podman attach command allows you to attach to a running container using the container's ID or name, either to view its ongoing output or to control it interactively.

Usage:
  podman attach [flags] CONTAINER
...
sudo podman create --help
Creates a new container from the given image or storage and prepares it for running the specified command. The container ID is then printed to stdout. You can then start it at any time with the podman start <container_id> command. The container will be created with the initial state 'created'.

Usage:
  podman create [flags] IMAGE [COMMAND [ARG...]]
