Description

The New-AzDataLakeGen2Item cmdlet creates a file or directory in a Filesystem in an Azure storage account. This cmdlet only works if Hierarchical Namespace is enabled for the Storage account. This kind of account can be created by run "New-AzStorageAccount" cmdlet with "-EnableHierarchicalNamespace $true".

Examples

Example 1: Create a directory with specified permission, Umask, properties, and metadata

New-AzDataLakeGen2Item -FileSystem "testfilesystem" -Path "dir1/dir2/" -Directory -Permission rwxrwxrwT -Umask ---rw---- -Property @{"CacheControl" = "READ"; "ContentDisposition" = "True"} -Metadata  @{"tag1" = "value1"; "tag2" = "value2" }

FileSystem Name: filesystem1

Path                 IsDirectory  Length          LastModified         Permissions  Owner                Group               
----                 -----------  ------          ------------         -----------  -----                -----

This command creates a directory with specified Permission, Umask, properties, and metadata

Example 2: Create(upload) a data lake file from a local source file, and the cmdlet runs in background

$task = New-AzDataLakeGen2Item  -FileSystem "testfilesystem" -Path "dir1/dir2/file1" -Source "c:\sourcefile.txt" -Force -asjob
$task | Wait-Job
$task.Output

FileSystem Name: filesystem1

Path                 IsDirectory  Length          LastModified         Permissions  Owner                Group                
----                 -----------  ------          ------------         -----------  -----                -----               
dir1/dir2/file1      False        14400000        2020-03-23 09:19:13Z rw-r-----    $superuser           $superuser

This command creates(upload) a data lake file from a local source file, and the cmdlet runs in background.

Example 3: Create(upload) a data lake file from a local source file and set its encryption context

$file = New-AzDataLakeGen2Item -FileSystem "testfilesystem" -Path "dir1/dir2/file1" -Source "c:\sourcefile.txt" -EncryptionContext "encryptioncontext"
$file.Properties.EncryptionContext

encryptioncontext

This command creates(upload) a data lake file from a local source file and sets its encryption context value to "encryptioncontext".
