# Command-Line Interface
Almost all interaction with Vagrant is done through the command-line
interface.
The interface is available using the `vagrant` command, and comes installed
with Vagrant automatically. The `vagrant` command in turn has many subcommands,
such as `vagrant up`, `vagrant destroy`, etc.
If you run `vagrant` by itself, help will be displayed showing all available
subcommands. In addition to this, you can run any Vagrant command with the
`-h` flag to output help about that specific command. For example, try
running `vagrant init -h`. The help will output a one sentence synopsis of
what the command does as well as a list of all the flags the command
accepts.
In depth documentation and use cases of various Vagrant commands is
available by reading the appropriate sub-section available in the left
navigational area of this site.
You may also wish to consult the
[documentation](/docs/other/environmental-variables) regarding the
environmental variables that can be used to configure and control
Vagrant in a global way.
## Autocompletion
Vagrant provides the ability to autocomplete commands. Currently, the
`bash` and `zsh` shells are supported. These can be enabled by running
`vagrant autocomplete install --bash --zsh`.
