Find All Fault Domains in an Availability Domain

To find all fault domains in the first available AD (Availability Domain) in the Sandbox compartment, run the following commands:

export sandbox_ocid=$(       \
    oci iam compartment list \
        --name 'Sandbox'     \
        --query 'data[0].id' \
        --raw-output         \
    )
export ad_name=$(                       \
    oci iam availability-domain list    \
        --compartment-id $sandbox_ocid  \
        --query 'data[0].name'          \
        --raw-output                    \
    )
oci iam fault-domain list                       \
    --query 'data[*].{"FD Name":name, OCID:id}' \
    --compartment-id $sandbox_ocid              \
    --availability-domain $ad_name              \
    --output table

Sample output is:
