The 1th example of the child command would be to use it to 'update base image updates to trigger on all dependent images of a multi stage dockerfile  and status of a task in an azure container registry', the syntax is: az acr task update -n MyTask -r myregistry --base-image-trigger-type All --status Disabled. The 2th example of the child command would be to use it to 'update platform for the build step of your task to windows  prev linux', the syntax is: az acr task update -n MyTask -r myregistry --platform Windows. The 3th example of the child command would be to use it to 'update task s triggers and context for an azure container registry', the syntax is: az acr task update -n hello-world -r myregistry -f Dockerfile \
