Contoh 4: Untuk mencantumkan nama Wilayah saja

Contoh describe-regions berikut menggunakan parameter --query untuk memfilter output dan hanya mengembalikan nama Wilayah sebagai teks.

aws ec2 describe-regions \
    --all-regions \
    --query "Regions[].{Name:RegionName}" \
    --output text

Output:

eu-north-1
ap-south-1
eu-west-3
eu-west-2
eu-west-1
ap-northeast-3
ap-northeast-2
me-south-1
ap-northeast-1

ca-central-1
ap-east-1
ap-southeast-1
ap-southeast-2
eu-central-1
us-east-1
us-east-2
us-west-1
