# Creating and deleting using a batch command
<a name="about-batch-update-schedule"></a>

To create and delete actions in the schedule for a channel, you use the batch update schedule command. This command lets you perform multiple actions in one request. There isn't one command for creating actions and another for deleting actions.

**Important**  
When working with a started and running channel, use the **batch-update-schedule** command to add or remove actions. Use the **delete-schedule** command only on idle channels. The **delete-schedule** command will delete all scheduled actions and could cause service interruptions if used on a live channel. 

You can use the command as follows:
+ Submit a *single* request such as a request to do the following:
  + Create one action.
  + Delete one action.
+ Submit a *batch* request such as one request to do the following:
  + Create several actions.
  + Delete several actions.
  + Create one or more actions and delete one or more actions.

**Important**  
In a command that combines create actions and delete actions, the delete actions are *always* performed before the create actions. This means that MediaLive removes the delete actions from the schedule before it adds the create actions to the schedule.
