# Command: apply
The `terraform apply` command is used to apply the changes required
to reach the desired state of the configuration, or the pre-determined
set of actions generated by a `terraform plan` execution plan.
## Usage
Usage: `terraform apply [options] [dir-or-plan]`
By default, `apply` scans the current directory for the configuration
and applies the changes appropriately. However, a path to another configuration
or an execution plan can be provided. Execution plans can be used to only
execute a pre-determined set of actions.
The `dir` argument can also be a [module source](/docs/modules/index.html).
In this case, `apply` behaves as though `init` were called with that
argument followed by an `apply` in the current directory. This is meant
as a shortcut for getting started.
The command-line flags are all optional. The list of available flags are:
* `-backup=path` - Path to the backup file. Defaults to `-state-out` with
the ".backup" extension. Disabled by setting to "-".
* `-input=true` - Ask for input for variables if not directly set.
* `-no-color` - Disables output with coloring.
* `-parallelism=n` - Limit the number of concurrent operation as Terraform
[walks the graph](/docs/internals/graph.html#walking-the-graph).
* `-refresh=true` - Update the state for each resource prior to planning
and applying. This has no effect if a plan file is given directly to
apply.
* `-state=path` - Path to the state file. Defaults to "terraform.tfstate".
Ignored when [remote state](/docs/state/remote.html) is used.
* `-state-out=path` - Path to write updated state file. By default, the
`-state` path will be used. Ignored when
[remote state](/docs/state/remote.html) is used.
* `-target=resource` - A [Resource
Address](/docs/internals/resource-addressing.html) to target. Operation will
be limited to this resource and its dependencies. This flag can be used
multiple times.
* `-var 'foo=bar'` - Set a variable in the Terraform configuration. This flag
can be set multiple times. Variable values are interpreted as
[HCL](/docs/configuration/syntax.html#HCL), so list and map values can be
specified via this flag.
* `-var-file=foo` - Set variables in the Terraform configuration from
a [variable file](/docs/configuration/variables.html#variable-files). If
"terraform.tfvars" is present, it will be automatically loaded first. Any
files specified by `-var-file` override any values in a "terraform.tfvars".
This flag can be used multiple times.
