Run a command against each GCP project in the current account
This is powerful so use carefully!
Requires GCloud SDK to be installed and configured and 'gcloud' to be in the \$ PATH
All arguments become the command template
The following command template tokens are replaced in each iteration:
Project ID: { id} { project_id}
Project Name: { name} { project_name}
eg.
${ 0 ##*/ } 'echo GCP project has id {id} and name {name}'
For a more useful example, see:
