     6    The `terraform refresh` command is used to reconcile the state Terraform knows about (via its state file) with the real-world infrastructure. This can be used to detect any drift from the last-known state, and to update the state file.

     9  # Command: refresh
    10  
    11  The `terraform refresh` command is used to reconcile the state Terraform
    12  knows about (via its state file) with the real-world infrastructure.
    13  This can be used to detect any drift from the last-known state, and to
    14  update the state file.
    15  
    16  This does not modify infrastructure, but does modify the state file.
    17  If the state is changed, this may cause changes to occur during the next
    18  plan or apply.
    19  
    20  ## Usage
    21  
    22  Usage: `terraform refresh [options] [dir]`
    23  
    24  By default, `refresh` requires no flags and looks in the current directory
    25  for the configuration and state file to refresh.
    26  
    27  The command-line flags are all optional. The list of available flags are:
    28  
    29  * `-backup=path` - Path to the backup file. Defaults to `-state-out` with
    30    the ".backup" extension. Disabled by setting to "-".
    31  
    32  * `-no-color` - Disables output with coloring
    33  
    34  * `-state=path` - Path to read and write the state file to. Defaults to "terraform.tfstate".
    35  
    36  * `-state-out=path` - Path to write updated state file. By default, the
    37    `-state` path will be used.
    38  
    39  * `-target=resource` - A [Resource
    40    Address](/docs/internals/resource-addressing.html) to target. Operation will
    41    be limited to this resource and its dependencies. This flag can be used
    42    multiple times.
    43  
    44  * `-var 'foo=bar'` - Set a variable in the Terraform configuration. This
    45    flag can be set multiple times.
    46  
    47  * `-var-file=foo` - Set variables in the Terraform configuration from
    48     a file. If "terraform.tfvars" is present, it will be automatically
    49     loaded if this flag is not specified.
