Modifies the user access control list (ACL) and displays authorization settings for a Git repository or branch within a Git repository.

Prerequisites

To view permissions, you must be able to view the artifact for the type of information you are requesting: View collection-level information for project collections, View project-level information for projects, and Read for repository (and branch if you are viewing branch permissions).
To manage permissions, you must have Manage permissions for the desired artifact.

For more information, see Default Git permissions.

Syntax

tf git permission [/allow:(* |perm1[,perm2,...]] 
                  [/deny:(* |perm1[,perm2,...])]
                  [/remove:(* |perm1[,perm2,...])]
                  [/user:username1[,username2,...]]
                  [/group:groupname1[,groupname2,...]]

                  [/teamproject:TeamProjectIdentifier]
                  [/repository:RepositoryIdentifier]
                  [/branch:BranchName]

Examples

Note

The following examples are broken into multiple lines for readability. To copy and paste them into the command-line and run them, first copy them and paste them into notepad or another tool and edit them so the commands are contained on a single line.

View collection level permissions

The following examples lists the permissions for the fabrikam-fiber collection.

tf git permission /collection:https://dev.azure.com/fabrikam-fiber 
                  /login:FabrikamUser@hotmail.com,FabrikamPassword

View project level permissions

The following examples lists the project level permissions for the FabrikamFiber project which is in the fabrikam-fiber collection.

tf git permission /collection:https://dev.azure.com/fabrikam-fiber 
                  /teamproject:FabrikamFiber
                  /login:FabrikamUser@hotmail.com,FabrikamPassword

View repository level permissions

The following examples lists the project level permissions for the FabrikamFiber repository which is in the FabrikamFiber project.

tf git permission /collection:https://dev.azure.com/fabrikam-fiber 
                  /teamproject:FabrikamFiber 
                  /repository:FabrikamFiber 
                  /login:FabrikamUser@hotmail.com,FabrikamPassword

Require branch folders commands

The following examples show how to create a branch policy that enforces the following constraints:

Only master can exist at the repository root.
All users will be allowed to create branches under the features/ and users/ folders.
Administrators will be able to create branches under the releases/ folder.

In this example we'll use the following collection, project, and repository:

/collection:https://fabrikam-fiber.visualstudio.com
/teamproject:FabrikamProject
/repository:FabrikamRepo

First, block the Create Branch permission at the repository root for the project's contributors.

tf git permission /deny:CreateBranch 
                  /group:[FabrikamProject]\Contributors 
                  /collection:https://dev.azure.com/fabrikam-fiber/ 
                  /teamproject:FabrikamProject 
                  /repository:FabrikamRepo

Then, allow contributors to create branches under features and users.

tf git permission /allow:CreateBranch 
                  /group:[FabrikamProject]\Contributors 
                  /collection:https://dev.azure.com/fabrikam-fiber/ 
                  /teamproject:FabrikamProject 
                  /repository:FabrikamRepo 
                  /branch:features

tf git permission /allow:CreateBranch 
                  /group:[FabrikamProject]\Contributors 
                  /collection:https://dev.azure.com/fabrikam-fiber/ 
                  /teamproject:FabrikamProject 
                  /repository:FabrikamRepo 
                  /branch:users

Allow administrators to create branches under releases.

tf git permission /allow:CreateBranch 
                  /group:"[FabrikamProject]\Project Administrators" 
                  /collection:https://dev.azure.com/fabrikam-fiber/ 
                  /teamproject:FabrikamProject 
                  /repository:FabrikamRepo 
                  /branch:releases

Finally, allow administrators to create a branch called master (in case it ever gets deleted accidentally).

tf git permission /allow:CreateBranch 
                  /group:"[FabrikamProject]\Project Administrators" 
                  /collection:https://dev.azure.com/fabrikam-fiber/ 
                  /teamproject:FabrikamProject 
                  /repository:FabrikamRepo 
                  /branch:master
