9 # Terraform Commands (CLI)
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 ```text
23 $ terraform
24 Usage: terraform [--version] [--help] <command> [args]
25
26 The available commands for execution are listed below.
27 The most common, useful commands are shown first, followed by
28 less common or more advanced commands. If you're just getting
29 started with Terraform, stick with the common commands. For the
30 other commands, please read the help and docs before usage.
31
32 Common commands:
33 apply Builds or changes infrastructure
34 console Interactive console for Terraform interpolations
35 destroy Destroy Terraform-managed infrastructure
36 fmt Rewrites config files to canonical format
37 get Download and install modules for the configuration
38 graph Create a visual graph of Terraform resources
39 import Import existing infrastructure into Terraform
40 init Initialize a new or existing Terraform configuration
41 output Read an output from a state file
42 plan Generate and show an execution plan
43 providers Prints a tree of the providers used in the configuration
44 push Upload this Terraform module to Terraform Enterprise to run
45 refresh Update local state file against real resources
46 show Inspect Terraform state or plan
47 taint Manually mark a resource for recreation
48 untaint Manually unmark a resource as tainted
49 validate Validates the Terraform files
50 version Prints the Terraform version
51 workspace Workspace management
52
53 All other commands:
54 debug Debug output management (experimental)
55 force-unlock Manually unlock the terraform state
56 state Advanced state management
57 ```
58
59 To get help for any specific command, pass the -h flag to the relevant subcommand. For example,
60 to see help about the graph subcommand:
61
62 ```text
63 $ terraform graph -h
64 Usage: terraform graph [options] PATH
65
66 Outputs the visual graph of Terraform resources. If the path given is
67 the path to a configuration, the dependency graph of the resources are
68 shown. If the path is a plan file, then the dependency graph of the
69 plan itself is shown.
70
71 The graph is outputted in DOT format. The typical program that can
72 read this format is GraphViz, but many web services are also available
73 to read this format.
74 ```
75
76 ## Shell Tab-completion
77
78 If you use either `bash` or `zsh` as your command shell, Terraform can provide
79 tab-completion support for all command names and (at this time) _some_ command
80 arguments.
81
82 To add the necessary commands to your shell profile, run the following command:
83
84 ```bash
85 terraform -install-autocomplete
86 ```
87
88 After installation, it is necessary to restart your shell or to re-read its
89 profile script before completion will be activated.
90
91 To uninstall the completion hook, assuming that it has not been modified
92 manually in the shell profile, run the following command:
93
94 ```bash
95 terraform -uninstall-autocomplete
96 ```
97
98 Currently not all of Terraform's subcommands have full tab-completion support
99 for all arguments. We plan to improve tab-completion coverage over time.
100
101 ## Upgrade and Security Bulletin Checks
102
103 The Terraform CLI commands interact with the HashiCorp service
104 [Checkpoint](https://checkpoint.hashicorp.com/) to check for the availability
105 of new versions and for critical security bulletins about the current version.
106
107 One place where the effect of this can be seen is in `terraform version`, where
108 it is used by default to indicate in the output when a newer version is
109 available.
110
111 Only anonymous information, which cannot be used to identify the user or host,
112 is sent to Checkpoint. An anonymous ID is sent which helps de-duplicate warning
113 messages. Both the anonymous id and the use of checkpoint itself are completely
114 optional and can be disabled.
115
116 Checkpoint itself can be entirely disabled for all HashiCorp products by
117 setting the environment variable `CHECKPOINT_DISABLE` to any non-empty value.
118
119 Alternatively, settings in
120 [the CLI configuration file](/docs/commands/cli-config.html) can be used to
121 disable checkpoint features. The following checkpoint-related settings are
122 supported in this file:
123
124 * `disable_checkpoint` - set to `true` to disable checkpoint calls
125 entirely. This is similar to the `CHECKPOINT_DISABLE` environment variable
126 described above.
127
128 * `disable_checkpoint_signature` - set to `true` to disable the use of an
129 anonymous signature in checkpoint requests. This allows Terraform to check
130 for security bulletins but does not send the anonymous signature in these
131 requests.
132
133 [The Checkpoint client code](https://github.com/hashicorp/go-checkpoint) used
134 by Terraform is available for review by any interested party.
