# Command CLI Options
Commands can also have their own *CLI options*.
In fact, each command can have different *CLI arguments* and *CLI options*:
{* docs_src/commands/options/tutorial001_an.py hl[8,14:17,27:29,38] *}
Here we have multiple commands, with different *CLI parameters*:
* `create`:
* `username`: a *CLI argument*.
* `delete`:
* `username`: a *CLI argument*.
* `--force`: a *CLI option*, if not provided, it's prompted.
* `delete-all`:
* `--force`: a *CLI option*, if not provided, it's prompted.
* `init`:
* Doesn't take any *CLI parameters*.
<div class="termy">
```console
// Check the help
python main.py --help
Usage: main.py [OPTIONS] COMMAND [ARGS]...
Options:
--install-completion Install completion for the current shell.
--show-completion Show completion for the current shell, to copy it or customize the installation.
--help Show this message and exit.
Commands:
create
delete
delete-all
init
```
</div>
/// tip
Check the command `delete-all`, by default command names are generated from the function name, replacing `_` with `-`.
///
Test it:
<div class="termy">
```console
// Check the command create
$ python main.py create Camila
Creating user: Camila
// Now test the command delete
$ python main.py delete Camila
# Are you sure you want to delete the user? [y/n]: $ y
Deleting user: Camila
$ python main.py delete Wade
# Are you sure you want to delete the user? [y/n]: $ n
Operation cancelled
// And finally, the command delete-all
// Notice it doesn't have CLI arguments, only a CLI option
$ python main.py delete-all
# Are you sure you want to delete ALL users? [y/n]: $ y
Deleting all users
$ python main.py delete-all
# Are you sure you want to delete ALL users? [y/n]: $ n
Operation cancelled
// And if you pass the --force CLI option, it doesn't need to confirm
$ python main.py delete-all --force
Deleting all users
// And init that doesn't take any CLI parameter
$ python main.py init
Initializing user database
```
</div>
