How do I add a startup script to an existing VM from the developer console?

Question

I have an existing, already configured VM on Google Cloud Platform. It was created without a startup script, but I\'d like to add one now.

How do I add it from the conso

Answer 1

The above answer is correct as per the question.

But what I was looking for to add multiple .sh scripts in startup metadata of GCP VM via gcloud command.

Below works for me (maybe it will help someone)

To add multiple key-value pairs at once, separate them with commas:

$ gcloud compute instances add-metadata test-instance \
      --metadata=important-data="2 plus 2 equals\
   4",unimportant-data=zero
