Add flag to list all lambda functions currently in account by name only

[xkjjx]

Describe the feature

Something like aws lambda list-functions that will result in:

my-function-1
my-function-2
my-function-3

Use Case

Can see what functions I have on my account easily instead of navigating lengthy JSONs.

Proposed Solution

Add a --name-only or --concise flag to the list-functions command to implement the functionality I described.

Hello @xkjjx, thanks for reaching out. Would this be the same as your request by adding --query parameter:
aws lambda list-functions --query 'Functions[].FunctionName' --output text

As per the CLI doc for list-functions, you could use --query to filter response.

Hi @adev-code - yes that is a good point. However, I think it is intuitive that something called list-functions should have the option I suggested as default, because the phrase "list" generally doesn't entail that every single detail about the object also be included. However I know this might be too built-in to change, which is why I was suggesting an easy flag to accomplish the same thing.

With that being said, I understand this is a matter opinion, so I understand if you guys don't share my views.

Thanks for the reply. I have reached out to the Lambda Service Team for the feature request. I do not have any timelines on when/if the team is going to release. Moving forward, please refer to the changelogs: V1 and V2.
