Команда TASKLIST — отобразить список задач на локальном или удаленном компьютере.

Команда TASKLIST используется для получения списка процессов, выполняющихся на локальном или удаленном компьютере в данный момент времени.

Формат командной строки:

Примеры использования TASKLIST.

tasklist /? — выдать краткую справку по использованию команды.

tasklist — отобразить на экране консоли список процессов выполняющихся на локальном компьютере в данный момент времени. Пример отображаемой информации

Имя образа — имя исполняемого файла данного процесса. System Idle Process — это не имя образа, а индикация режима простоя, когда ни один из процессов не выполняется.

PID — уникальный идентификатор процесса. Присваивается процессу при его создании.

Имя сессии — имя сессии отображает признак Services — процесс запущен в качестве системной службы, Console — интерактивный пользовательский процесс, RDP-Tcp#n — процесс, созданный удаленным подключением по RDP ( клиентами служб терминалов) — .

№ сеанса — номер сеанса пользователя.

Память — объем используемой процессом памяти.

tasklist /FO LIST — то же, что и в предыдущем примере, но выводимые данные представлены в виде списка:

tasklist /FO CSV — отобразить список процессов в формате полей, разделяемых запятой:

tasklist /fo csv /nh — то же, что и в предыдущем примере, но строка заголовка с названием колонок не отображается ( 1-я строка ).

tasklist -S SERVER — отобразить список процессов выполняющихся на удаленном компьютере SERVER в данный момент времени.

tasklist /m wsock32.dll — отобразить список процессов, которые подгружают библиотеку wsock32.dll . Пример отображаемых результатов выполнения команды:

tasklist /m — если имя модуля не задано, то отображается весь список процессов, и по каждому процессу — весь список модулей. Пример результата выполнения команды:

tasklist /SVC — отобразить информацию о системных службах. Пример:

В колонке Службы отображается короткое имя службы, например, DcomLaunch — для Службы Терминалов

tasklist -s 192.168.0.1 -U mydomain\admin -P mypass /FI «memusage gt 10000» — отобразить список процессов, использующих более 10000кб ( 10 Мб) памяти на компьютере с IP-адресом 192.168.0.1 . При подключении к удаленному компьютеру используется имя пользователя admin в домене mydomain и пароль mypass

tasklist /fi «username ne NT AUTHORITY\Система» | more — отобразить список процессов, выполняющихся не от имени локальной системной учетной записи. Для некоторых версий Windows, вместо русского Система нужно использовать System . Команда объединена в цепочку с more для организации постраничного вывода на экран.

tasklist -s 192.168.0.110 -U mydomain\admin -P mypass /FI «sessionname eq RDP*» — отобразить список процессов на удаленном компьютере, созданных клиентами служб терминалов.

Кроме получения чисто справочной информации о выполняющихся в системе процессах, команда TASKLIST обычно используется как средство получения исходных данных для команды принудительного завершения процессов TASKKIll

GET (HPC Pack 2016)	https://head_node_name:port/WindowsHPC/Job/job_identifier/Tasks

For instances of the REST web service that are hosted in Azure, the head node name should have a format of Windows_Azure_service_name.cloudapp.net.

To get the name to use for an HPC cluster that runs at least Microsoft HPC Pack 2008 R2 with Service Pack 3 (SP3), use the Get Clusters operation.

URI Parameters

You can specify the following additional parameters on the request URI.

Optional. A comma-separated list of the names for the properties of the tasks for which you want to get values.

If you do not specify the Properties parameter, the response contains values for the TaskId, Name, State, CommandLine, ExitCode, ParentJobId, JobTaskId, and InstanceId properties. For a list of the properties that you can specify, see the Remarks section.

If a property with a specified name does not exist for a task, an error occurs.

Optional. Specifies whether to get properties only for the master task for a parametric sweep task, or for all of the subtasks instead. True indicates that you want to get properties for all of the subtasks. False indicates that you want to get properties only for the master task. The default value is True.

Specifies internal data from the x-ms-continuation-QueryId header from the response in the previous Get Task List operation in a continuation sequence of Get Task List operations. For more information, see the Response Headers section later in this topic.

Specifies internal data from the x-ms-continuation-CurrentObjectNumber header from the response in the previous Get Task List operation in a set of Get Task List operations. For more information, see the Response Headers section later in this topic. Deprecated starting with Microsoft HPC Pack 2008 R2 with Service Pack 3 (SP3).

Optional. Specifies the version of the operation to use for this request. To specify MicrosoftВ HPCВ PackВ 2008В R2 with ServiceВ PackВ 3 (SP3), use a value of 2011-11-01. The minimum version that supports this URI parameter is MicrosoftВ HPCВ PackВ 2008В R2 with SP3.

The value of this URI parameter is ignored if the request also contains the api-version header.

Optional. Specifies OData filters to use for this request in the following format «$filter= %20and%20 …».

To filter the tasks by a valid task state, use the filter «TaskState%20eq%20 «. To retrieve tasks whose state changed after a certain date and time, use the filter «ChangeTimeFrom%20eq%20 «.

A null value is ignored.

The minimum version that supports this URI parameter is Microsoft HPC Pack 2012. To use this parameter, also specify the Render URI parameter set to RestPropRender and a minimum api-version value of 2012-11-01.

Example: «$filter=TaskState%20eq%20queued%20and%20 ChangeTimeFrom%20eq%202015-10-16&Render=RestPropRender&api-version=2012-11-01». For information about task states, see TaskState.

Parameter	Description

Request Headers

The following table describes required and optional request headers.

Optional. Specifies the version of the operation to use for this request. To specify MicrosoftВ HPCВ PackВ 2008В R2 with SP3, use a value of 2011-11-01. The minimum version that supports this header is MicrosoftВ HPCВ PackВ 2008В R2 with SP3.

The value specified in this header overrides the value specified in the api-version URI parameter if both are specified.

Optional. Specifies the version of the operation to use for this request.

Deprecated beginning with Microsoft HPC Pack 2008 R2 with Service Pack 3 (SP3).

Request Body

Response

The response includes an HTTP status code, a set of response headers, and a response body in XML format.

Status Code

A successful operation returns status code 200 (OK). For more information about status codes, see HttpStatusCode.

The error response is dependent upon the api-version used in the request. If the api-version is not provided, or CCP_Version is specified, then the error response will be an XML string (Note: The error message will vary based on the error):

If the api-version is 2011-11-01 or later, the error message will be a more descriptive XML response (Note: Values will vary based on the error):

Response Headers

The response for this operation includes the following headers.

Request Header	Description
api-version

A comma-separated list of RFC 1918 IP addresses that indicate the sequence of instances of the REST web service that the operation called in order from to right.

Only responses from instances of the REST web service that are hosted on Azure contain this header. Responses from instances of the REST web service that are hosted on premise omit this header.

This header is supported beginning with Microsoft HPC Pack 2008 R2 with SP3 and is not available in previous versions.

Enables large sets of data to be returned in smaller responses across a continuation sequence of several requests. The value of this header is to be assigned to the queryId query string parameter in the next call in the sequence of calls to the Get Task List operation. The response to the Get Task List operation contains this header as long as additional data remains to be processed. You use the values of this header for one operation in the queryId URI parameter for the next operation.

The format of the data in this header is not guaranteed to remain unchanged. You should only copy the data in this header from one operation in a set of multiple operations to the queryId URI parameter for the next operation. You should not use the data in this header or depend on the format of the data in this header in any other way.

For an example of how to use this header and URI parameter in a way that potential changes will not impact, see the code for the sample client applications for REST API. For information about how to get these sample client applications, see Getting Sample Programs that use the REST API.

Contains internal data that support working with sets of data that are too large or too expensive to get in a single response body by dividing the Get Task List operation into a set of multiple Get Task List operations. The response to the Get Task List operation contains this header as long as additional data remains to be processed. You use the values of this header for one operation in the CurrentObjectNumber URI parameter for the next operation.

The format of the data in this header is not guaranteed to remain unchanged. You should only copy the data in this header from one operation in a set of multiple operations to the CurrentObjectNumber URI parameter for the next operation. You should not use the data in this header or depend on the format of the data in this header in any other way.

For an example of how to use this header and URI parameter in a way that potential changes will not impact, see the code for the sample client applications for REST API.

Deprecated starting with Microsoft HPC Pack 2008 R2 with SP3.

The response for this operation also includes standard HTTP headers. All standard headers conform to the HTTP/1.1 protocol specification.

Response Body

The format of the response body is as follows.

The following table describes each of the elements in the response XML.

Response Header	Description
x-ms-hpc-authoritychain
x-ms-continuation-CurrentObjectNumber

Represents the set of tasks in the specified job.

Represents a single task.

Represents the set of properties for the task.
