How to run a script or a command on EC2 instance via AWS CLI?

According to New EC2 Run Command news article, AWS CLI should support a new sub-command to execute scripts on remote EC2 instances.

However I've checked in aws ec2 help, but I can't find the relevant command.

I've installed aws via apt-get:

$ aws --version
aws-cli/1.14.32 Python/3.5.4 Linux/4.12.7-64 botocore/1.8.36

Which sub-command I should look for and what's the syntax to run, let say ipconfig in PowerShell on the remote EC2 instance?

To run ipconfig from the AWS Systems Manager Run Command:

$ aws ssm send-command --document-name "AWS-RunPowerShellScript" --instance-ids "" --parameters commands=ipconfig

Note: If you've got the error, consider specifying the right --region.

This assumes you have your AWS credentials and CLI configured properly. See Systems Manager Run Command Walkthrough Using the AWS CLI for more information.

Here is the practical shell command example of sending and getting the command output:

cmdid=$(aws ssm send-command --instance-ids "i-ch3ng3th1s" --document-name "AWS-RunPowerShellScript" --parameters commands=ipconfig --query "Command.CommandId" --output text)
aws ssm list-command-invocations --command-id "$cmdid" --details --query "CommandInvocations[*].CommandPlugins[*].Output[]" --output text
