# Managing Waffle data from the command line

Aside the Django admin interface, you can use the command line tools to manage all your waffle objects.

## Flags

Use `manage.py` to change the values of your flags:

    $ ./manage.py waffle_flag name-of-my-flag --everyone --percent=47

Use `--everyone` to turn on and `--deactivate` to turn off the flag. Set a percentage with `--percent` or `-p`. Set the flag on for superusers (`--superusers`), staff (`--staff`) or authenticated (`--authenticated`) users. Set the rollout mode on with `--rollout` or `-r`.

If the flag doesn’t exist, add `--create` to create it before setting its values:

    $ ./manage.py waffle_flag name-of-my-flag --deactivate --create

To list all the existing flags, use `-l`:

    $ ./manage.py waffle_flag -l
    Flags:
    name-of-my-flag

## Switches

Use `manage.py` to change the values of your switches:

    $ ./manage.py waffle_switch name-of-my-switch off

You can set a switch to `on` or `off`. If that switch doesn’t exist, add `--create` to create it before setting its value:

    $ ./manage.py waffle_switch name-of-my-switch on --create

To list all the existing switches, use `-l`:

    $ ./manage.py waffle_switch -l
    Switches:
    name-of-my-switch on

## Samples

Use `manage.py` to change the values of your samples:

    $ ./manage.py waffle_sample name-of-my-sample 100

You can set a sample to any floating value between `0.0` and `100.0`. If that sample doesn’t exist, add `--create` to create it before setting its value:

    $ ./manage.py waffle_sample name-of-my-sample 50.0 --create

To list all the existing samples, use `-l`:

    $ ./manage.py waffle_sample -l
    Samples:
    name-of-my-sample: 50%

## Deleting Data

Use `manage.py` to delete a batch of flags, switches, and/or samples:

    $ ./manage.py waffle_delete --switches switch_name_0 switch_name_1 --flags flag_name_0 flag_name_1 --samples sample_name_0 sample_name_1

Pass a list of switch, flag, or sample names to the command as keyword arguments and they will be deleted from the database.
