# Desc:   Utility script that allows you to find the same ami(name) across multiple regions. 
#         For instance, let's suppose that you want to find the Ubuntu Server 16.04 LTS HVM SSD 
#         to build a nice cloudformation template. Note that you can play around with the filters
#         that AWSCLI provides. Have fun ;)
# Usage: 
#         find_ami_in_multiple_regions.sh ami-e93da085 (Obs.: This ami must be at same region your AWS is set)
# Output: 
#         ap-south-1      - ami-0355216c
#         eu-west-1       - ami-0d77397e
#         ap-northeast-2  - ami-8fed39e1
#         ap-northeast-1  - ami-0567c164
#         sa-east-1       - ami-e93da085
#         ap-southeast-1  - ami-a1288ec2
#         ap-southeast-2  - ami-4d3b062e
#         eu-central-1    - ami-8504fdea
#         us-east-1       - ami-40d28157
#         us-east-2       - ami-153e6470
#         us-west-1       - ami-6e165d0e
#         us-west-2       - ami-a9d276c9
