There is a command group 'az_datafactory_pipeline'. This group of commands could 'manage pipeline with datafactory'. The group of commands has global parameter '--debug' which means 'Increase logging verbosity to show all debug logs.'. The group of commands has global parameter '--help -h' which means 'Show this help message and exit.'. The group of commands has global parameter '--only-show-errors' which means 'Only show errors, suppressing warnings.'. The group of commands has global parameter '--output -o' which means 'Output format.'. The group of commands has global parameter '--query' which means 'JMESPath query string. See <a href="http://jmespath.org/">http://jmespath.org/</a> for more information and examples.'. The group of commands has global parameter '--subscription' which means 'Name or ID of subscription. You can configure the default subscription using `az account set -s NAME_OR_ID`.'. The group of commands has global parameter '--verbose' which means 'Increase logging verbosity. Use --debug for full debug logs.'. This group contains a child command 'az_datafactory_pipeline_update'.The syntax is: az datafactory pipeline update [--activities]

                               [--variables]. The 1th example of the child command would be to use it to 'pipelines_update', the syntax is: az datafactory pipeline update --factory-name "exampleFactoryName" --description "Example description" --activities "[{\"name\":\"ExampleForeachActivity\",\"type\":\"ForEach\",\"typeProperties\":{\"activities\":[{\"name\":\"ExampleCopyActivity\",\"type\":\"Copy\",\"inputs\":[{\"type\":\"DatasetReference\",\"parameters\":{\"MyFileName\":\"examplecontainer.csv\",\"MyFolderPath\":\"examplecontainer\"},\"referenceName\":\"exampleDataset\"}],\"outputs\":[{\"type\":\"DatasetReference\",\"parameters\":{\"MyFileName\":{\"type\":\"Expression\",\"value\":\"@item()\"},\"MyFolderPath\":\"examplecontainer\"},\"referenceName\":\"exampleDataset\"}],\"typeProperties\":{\"dataIntegrationUnits\":32,\"sink\":{\"type\":\"BlobSink\"},\"source\":{\"type\":\"BlobSource\"}}}],\"isSequential\":true,\"items\":{\"type\":\"Expression\",\"value\":\"@pipeline().parameters.OutputBlobNameList\"}}}]" --parameters "{\"OutputBlobNameList\":{\"type\":\"Array\"}}" --duration "0.00:10:00" --name "examplePipeline" --resource-group "exampleResourceGroup". The parameter '--activities' is optional. list of activities in pipeline. expected value: json-string/json-file/@json-file.. The parameter '--add' is optional. add an object to a list of objects by specifying a path and key value pairs.  example: `--add property.listproperty <key=value, string or json string>`.. The parameter '--annotations' is optional. list of tags that can be used for describing the pipeline. expected value: json-string/json-file/@json-file.. The parameter '--concurrency' is optional. the max number of concurrent runs for the pipeline.. The parameter '--description' is optional. the description of the pipeline.. The parameter '--duration' is optional. timespan value, after which an azure monitoring metric is fired. expected value: json-string/json-file/@json-file.. The parameter '--factory-name' is optional. the factory name.. The parameter '--folder-name' is optional. the name of the folder that this pipeline is in.. The parameter '--force-string' is optional. when using 'set' or 'add', preserve string literals instead of attempting to convert to json.. The parameter '--ids' is optional. one or more resource ids (space-delimited). it should be a complete resource id containing all information of 'resource id' arguments. you should provide either --ids or other 'resource id' arguments.. The parameter '--if-match' is optional. etag of the pipeline entity.  should only be specified for update, for which it should match existing entity or can be * for unconditional update.. The parameter '--if-none-match' is optional. etag of the pipeline entity. should only be specified for get. if the etag matches the existing entity tag, or if * was provided, then no content will be returned. default value is none.. The parameter '--name --pipeline-name -n' is optional. the pipeline name.. The parameter '--parameters' is optional. list of parameters for pipeline. expected value: json-string/json-file/@json-file.. The parameter '--remove' is optional. remove a property or an element from a list.  example: `--remove property.list <indextoremove>` or `--remove propertytoremove`.. The parameter '--resource-group -g' is optional. name of resource group. you can configure the default group using `az configure --defaults group=<name>`.. The parameter '--run-dimensions' is optional. dimensions emitted by pipeline. expected value: json-string/json-file/@json-file.. The parameter '--set' is optional. update an object by specifying a property path and value to set.  example: `--set property1.property2=<value>`..
