    10  
    11  Terraform is controlled via a very easy to use command-line interface (CLI).
    12  Terraform is only a single command-line application: terraform. This application
    13  then takes a subcommand such as "apply" or "plan". The complete list of subcommands
    14  is in the navigation to the left.
    15  
    16  The terraform CLI is a well-behaved command line application. In erroneous cases,
    17  a non-zero exit status will be returned. It also responds to -h and --help as you'd
    18  most likely expect.
    19  
    20  To view a list of the available commands at any time, just run terraform with no arguments:
    21  
    22  ```
    23  $ terraform
    24  usage: terraform [--version] [--help] <command> [<args>]
    25  
    26  Available commands are:
    27      apply      Builds or changes infrastructure
    28      graph      Create a visual graph of Terraform resources
    29      output     Read an output from a state file
    30      plan       Generate and show an execution plan
    31      refresh    Update local state file against real resources
    32      show       Inspect Terraform state or plan
    33      version    Prints the Terraform version
    34  ```
    35  
    36  To get help for any specific command, pass the -h flag to the relevant subcommand. For example,
    37  to see help about the members subcommand:
    38  
    39  ```
    40  $ terraform graph -h
    41  Usage: terraform graph [options] PATH
    42  
    43    Outputs the visual graph of Terraform resources. If the path given is
    44    the path to a configuration, the dependency graph of the resources are
    45    shown. If the path is a plan file, then the dependency graph of the
    46    plan itself is shown.
    47  
    48    The graph is outputted in DOT format. The typical program that can
    49    read this format is GraphViz, but many web services are also available
    50    to read this format.
