# Get-AzureBatchSubtask
## SYNOPSIS
Gets the subtask information of the specified task.
## SYNTAX
### ODataFilter (Default)
```
Get-AzureBatchSubtask [-JobId] <String> [-TaskId] <String> [-MaxCount <Int32>]
 -BatchContext <BatchAccountContext> [-DefaultProfile <IAzureContextContainer>] [<CommonParameters>]
```
### ParentObject
```
Get-AzureBatchSubtask [[-Task] <PSCloudTask>] [-MaxCount <Int32>] -BatchContext <BatchAccountContext>
 [-DefaultProfile <IAzureContextContainer>] [<CommonParameters>]
```
## DESCRIPTION
The **Get-AzureBatchSubtask** cmdlet retrieves the subtask information about the specified task.
Subtasks provide parallel processing for individual tasks, and enable precise monitoring of task execution and progress.
## EXAMPLES
### Example 1: Return all subtasks for a specified task
```
PS C:\>$Context = Get-AzureRmBatchAccountKeys -AccountName "contosobatchaccount"
PS C:\> Get-AzureBatchSubtask -JobId "Job-01" -TaskID "myTask" -BatchContext $Context
```
These commands return all the subtasks for the task with the ID myTask.
To do this, the first command in the example creates an object reference to the account keys for the batch account contosobatchaccount.
This object reference is stored in a variable named $context.
The second command then uses that object reference and the **Get-AzureBatchSubtask** cmdlet to return all the subtasks for myTask, a task that runs as part of job Job-01.
## PARAMETERS
### -BatchContext
Specifies the **BatchAccountContext** instance that this cmdlet uses to interact with the Batch service.
If you use the Get-AzureRmBatchAccount cmdlet to get your BatchAccountContext, then Azure Active Directory authentication will be used when interacting with the Batch service. To use shared key authentication instead, use the Get-AzureRmBatchAccountKeys cmdlet to get a BatchAccountContext object with its access keys populated. When using shared key authentication, the primary access key is used by default. To change the key to use, set the BatchAccountContext.KeyInUse property.
```yaml
Type: BatchAccountContext
Parameter Sets: (All)
Aliases: 
Required: True
Position: Named
Default value: None
Accept pipeline input: True (ByValue)
Accept wildcard characters: False
```
### -DefaultProfile
The credentials, account, tenant, and subscription used for communication with azure.
```yaml
Type: IAzureContextContainer
Parameter Sets: (All)
Aliases: AzureRmContext, AzureCredential
Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
```
### -JobId
Specifies the ID of the job that contains the task whose subtasks this cmdlet gets.
```yaml
Type: String
Parameter Sets: ODataFilter
Aliases: 
Required: True
Position: 0
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False
```
### -MaxCount
Specifies the maximum number of subtasks to return.
If you specify a value of zero (0) or less, the cmdlet does not use an upper limit.
The default value is 1000.
```yaml
Type: Int32
Parameter Sets: (All)
Aliases: 
Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
```
### -Task
Specifies an object reference to the task that contain the subtasks that this cmdlet returns.
This object reference is created by using the Get-AzureBatchTask cmdlet and storing the returned object in a variable.
```yaml
Type: PSCloudTask
Parameter Sets: ParentObject
Aliases: 
Required: False
Position: 0
Default value: None
Accept pipeline input: True (ByValue)
Accept wildcard characters: False
```
### -TaskId
Specifies the ID of the task whose subtasks this cmdlet returns.
```yaml
Type: String
Parameter Sets: ODataFilter
Aliases: 
Required: True
Position: 1
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False
```
### CommonParameters
