Usage: terraform lock [DIR]
Manually lock the state for the defined configuration.
This will not modify your infrastructure. This command obtains a lock on the
state for the current configuration. The behavior of this lock is dependent
on the backend being used. A lock on a local state file only lasts for the
duration of the calling process.
