I am looking for a way to list all of the actions that can be used in a AWS IAM policy.

This is an example policy that uses IAM actions:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "Stmt1457442845000",
            "Effect": "Allow",
            "Action": [
                "iam:CreatePolicy",
                "iam:CreatePolicyVersion",
                "iam:GetGroupPolicy",
                "iam:CreateGroup",
                "iam:GetPolicy",
                "iam:GetPolicyVersion",
                "iam:GetRolePolicy",
                "iam:ListAttachedGroupPolicies"
            ],
            "Resource": [
                "*"
            ]
        }
    ]
}

I would like to search through actions from a file, and for that I would like to have all the available actions. I could not find a way yet to get that list. Any direction is appreciated.
