I'd vote for removing the COMMAND column instead. I don't think it's very useful. It would keep things simpler not thave this column at all.

[tealtail]

@aaronlehmann okay, yeah, that's much simpler :) I'll update this PR soon to remove the column

[thaJeztah]

We should think about adding a --format flag, so that users can customize the output. I'll check if there's an issue for that already, otherwise open one

locally tests pass but the builds triggered by push here failed with

18:33:21 Error response from daemon: No such container: docker-pr-exp26009

@tealtail looks like this is the actual failure;

20:58:29 ---> Making bundle: validate-vet (in bundles/1.13.0-dev/validate-vet)
20:58:29 cli/command/service/list.go:112: missing argument for Fprintf("%s"): format reads arg 5, have only 4 args
20:58:29 cli/command/service/list.go:120: missing argument for Fprintf("%s"): format reads arg 5, have only 4 args
20:58:29 exit status 1

[tealtail]

ohhh thanks @thaJeztah okay, so I'm thinking the problem is that listItemFmt would need 1 less %s now? I'm running tests after making that change and will update the PR again tonight

[tealtail]

all builds are passing now 👍

[thaJeztah]

Awesome!

design LGTM, but a quick check with @aluzzardi if he agrees

[aluzzardi]

LGTM

We actually discussed removing this column a few days ago as it was consuming precious screen real estate with no meaningful use, so 👍

[aaronlehmann]

LGTM

[thaJeztah]

docs changes here LGTM, but ping @mstanleyjones as it's possible other parts of the docs have some example output that needs to be updated

[mdlinville]

Does it also affect service update, service rm, service inspect, etc?

[tealtail]

@mstanleyjones yes! some of those still have COMMAND output included in examples. Update incoming.

[tealtail]

@mstanleyjones I've updated this PR with the changes you requested

[mdlinville]

LGTM. cc @allencloud please sync #27710 with this change.
