This is currently only implemented for GitHub organizations.
To install use gh itself:
> gh extension install warpedpixel/gh-collaboratorsUsage is simple:
> gh collaborators SomeOrganizationIBelongToAssuming that you have access to that organization named SomeOrganizationIBelongTo, the extension will think for a bit and output JSON
that looks like the below. Colalborators will be listed once if they have access to any of the repos
under the organization, so for large organizations this may take some time.
[
{ "org" : "SomeOrganizationIBelongTo", "collaborators": [
"CoolProgrammer", "OctoCat"
]}
]Output is in JSON so it can be more easily parsed and queried by something like jq.
