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 * `-input=true` - Ask for input for variables if not directly set. 33 34 * `-lock=true` - Lock the state file when locking is supported. 35 36 * `-lock-timeout=0s` - Duration to retry a state lock. 37 38 * `-no-color` - If specified, output won't contain any color. 39 40 * `-state=path` - Path to read and write the state file to. Defaults to "terraform.tfstate". 41 Ignored when [remote state](/docs/state/remote.html) is used. 42 43 * `-state-out=path` - Path to write updated state file. By default, the 44 `-state` path will be used. Ignored when 45 [remote state](/docs/state/remote.html) is used. 46 47 * `-target=resource` - A [Resource 48 Address](/docs/internals/resource-addressing.html) to target. Operation will 49 be limited to this resource and its dependencies. This flag can be used 50 multiple times. 51 52 * `-var 'foo=bar'` - Set a variable in the Terraform configuration. This flag 53 can be set multiple times. Variable values are interpreted as 54 [HCL](/docs/configuration/syntax.html#HCL), so list and map values can be 55 specified via this flag. 56 57 * `-var-file=foo` - Set variables in the Terraform configuration from 58 a [variable file](/docs/configuration/variables.html#variable-files). If 59 a `terraform.tfvars` or any `.auto.tfvars` files are present in the current 60 directory, they will be automatically loaded. `terraform.tfvars` is loaded 61 first and the `.auto.tfvars` files after in alphabetical order. Any files 62 specified by `-var-file` override any values set automatically from files in 63 the working directory. This flag can be used multiple times.
