Usage: tofu [global options] state (remove|rm) [options] ADDRESS...
Remove one or more items from the OpenTofu state, causing OpenTofu to
"forget" those items without first destroying them in the remote system.
This command removes one or more resource instances from the OpenTofu state
based on the addresses given. You can view and list the available instances
with "tofu state list".
If you give the address of an entire module then all of the instances in
that module and any of its child modules will be removed from the state.
If you give the address of a resource that has "count" or "for_each" set,
all of the instances of that resource will be removed from the state.
Options:
-dry-run If set, prints out what would've been removed but
doesn't actually remove anything.
-backup=PATH Path where OpenTofu should write the backup
state.
-lock=false Don't hold a state lock during the operation. This is
dangerous if others might concurrently run commands
against the same workspace.
-lock-timeout=0s Duration to retry a state lock.
-state=PATH Path to the state file to update. Defaults to the
current workspace state.
-ignore-remote-version Continue even if remote and local OpenTofu versions
are incompatible. This may result in an unusable
workspace, and should be used with extreme caution.
-var 'foo=bar' Set a value for one of the input variables in the root
module of the configuration. Use this option more than
once to set more than one variable.
-var-file=filename Load variable values from the given file, in addition
to the default files terraform.tfvars and *.auto.tfvars.
Use this option more than once to include more than one
variables file.
-json Produce output in a machine-readable JSON format,
suitable for use in text editor integrations and other
automated systems. Always disables color.
-json-into=out.json Produce the same output as -json, but sent directly
to the given file. This allows automation to preserve
the original human-readable output streams, while
capturing more detailed logs for machine analysis.
