AWS CLI is an open-source tool that enables users to interact with AWS services using commands or scripts from the user command line shell. It helps the user to manage multiple AWS services and automate them using scripts.

NOTE: AWS CLI versions 1 and 2 use the same aws command name. If you previously installed AWS CLI version 1, Migrate from AWS CLI version 1 to version 2.

Check whether AWS is installed or not on your system

Run command aws --version on your command prompt & it should have the output as below:

$ aws --version
aws-cli/2.10.0 Python/3.11.2 Windows/10 exe/AMD64 prompt/off

  • List all EC2 instances aws ec2 describe-instances

Additionally, there can be queries & filters applied in the AWS CLI command to get specific output like getting the EC2 details that are running and in n. Virginia region.

aws ec2 describe-instances \
--query "Reservations[*].Instances[*]"  --region us-east-1 \
--filters "Name=instance-state-name,Values=running"

The result can be depicted in different formats like JSON or table & others.

aws ec2 describe-instances \
--query "Reservations[*].Instances[*]"  --region us-east-1 \
--filters "Name=instance-state-name,Values=running" --output table
