So far is possible to add a tag to a single device by using the command: "ibmcloud resource tag-attach --tag-names TAG --resource-name NAME". However, is NOT possible to do it for multiple devices. It should be great if it could work for multiple devices as well. It should be great as well, if could be possible to pass a file of names (like a list of devices that are already present in the IBM Cloud that you would like to add a tag).
Do not place IBM confidential, company confidential, or personal information into any field.
