Auto answer yes for command `gcloud compute instance-templates delete`

Question

To delete a gcloud instance template, we call

gcloud compute instance-templates delete TEMPLATE_NAME

But we have to answer a Y/n question which is not favored for automation bash script. We want auto answer yes, how?

p.s.

My google search for this question results little helpful.

Manual page of the command also has nothing about any other parameter.

gcloud help   compute instance-templates delete

Answer 1

gcloud has a set of global flags including --quiet to disable such prompts:

Answer 2

I agree that using --quiet is the best way in the case of gcloud commands.

But for a CLI tool that doesn't have such an option we can explicitly use printf like below:

printf 'yes' | gcloud compute instance-templates delete TEMPLATE_NAME

I hope this is useful (if not in this case, then somewhere else).
