Get the Default GCP Project ID with a Cloud SDK CLI One-Liner

Question

I’m looking for a gcloud one-liner to get the default project ID ($GCP_PROJECT_ID).

The list command gives me:

gcloud config list core/project

#=>

[core]
project = $GCP_PROJECT_ID

Your active configuration is: [default]

While I only want the following output:

gcloud . . .

#=>

$GCP_PROJECT_ID

Answer 1

The easiest way to do this is to use the --format flag with gcloud:

gcloud config list --format 'value(core.project)' 2>/dev/null

The --format flag is available on all commands and gives you full control over what is printed, and how it is formatted.
