# State Command
The `terraform state` command is used for advanced state management.
As your Terraform usage becomes more advanced, there are some cases where
you may need to modify the [Terraform state](/docs/state/index.html).
Rather than modify the state directly, the `terraform state` commands can
be used in many cases instead.
This command is a nested subcommand, meaning that it has further subcommands.
These subcommands are listed to the left.
## Usage
Usage: `terraform state <subcommand> [options] [args]`
Please click a subcommand to the left for more information.
## Remote State
The Terraform state subcommands all work with remote state just as if it
was local state. Reads and writes may take longer than normal as each read
and each write do a full network roundtrip. Otherwise, backups are still
written to disk and the CLI usage is the same as if it were local state.
## Backups
All `terraform state` subcommands that modify the state write backup
files. The path of these backup file can be controlled with `-backup`.
Subcommands that are read-only (such as [list](/docs/commands/state/list.html))
do not write any backup files since they aren't modifying the state.
Note that backups for state modification _can not be disabled_. Due to
the sensitivity of the state file, Terraform forces every state modification
command to write a backup file. You'll have to remove these files manually
if you don't want to keep them around.
## Command-Line Friendly
The output and command-line structure of the state subcommands is
designed to be easy to use with Unix command-line tools such as grep, awk,
etc. Consequently, the output is also friendly to the equivalent PowerShell
commands within Windows.
For advanced filtering and modification, we recommend piping Terraform
state subcommands together with other command line tools.
