+aws help
+aws --version     # Show the current AWS CLI version
+aws configure     # Configure your AWS Key ID, AWS Secret, default region and default output format for the AWS CLI
+aws configure --profile <profile_name> # Configure using the profile name. By default, the list of profile is stored in ~/.aws.credentials (Linux and MacOS)
+
+# EC2
+## We need to specify a region to use ec2 commands. We can configure a default region with "aws configure" or set the AWS_DEFAULT_REGION environment variable before the command line
+## Example: AWS_DEFAULT_REGION=us-east-1 aws ec2 describe-instances
+
+aws ec2 describe-instances # Desribe all instances in the current region
+aws ec2 describe-instances --instance-ids <instance_id_1> <instance_id_2> # Describe specific instances by their IDs
+aws ec2 describe-instances --filters Name=<instance_name> # Filter and describe instances by name

+
+aws s3 mv <local_file_path> s3://<bucket_name>/<destination_file_path> # Move a file in local_file_path to a specific bucket in destination_file_path
+## Example: aws s3 mv text.txt s3://mybucket/text.txt
+aws s3 mv s3://<bucket_name_1> s3://<bucket_name_2> --recursive # Move all objects from bucket_name_1 to bucket_name_2
+
+aws s3 sync <source> <target> # Sync all contents from source to a target directory. This will copy and update all missing or outdated files or objects between source and target
+## Examples: aws s3 sync . s3://mybucket
+##           aws s3 sync s3://bucket_1 s3://bucket_2
