Interagir com Links simbólicos usando cmdlets Item aprimoradosInteract with Symbolic links using improved Item cmdlets

Para dar suporte a links simbólicos, *-Item e alguns cmdlets relacionados foram estendidos.To support symbolic links, *-Item and a few related cmdlets have been extended. Agora, é possível criar links simbólicos em uma única linha simples com New-Item.Now you can create symbolic links in a single, simple line with New-Item. Você observará que os cmdlets relacionados a Item (Remove-Item, Get-ChildItem) se comportam de maneira muito semelhante quando comparado a situações anteriores.You’ll notice that the Item-related cmdlets (Remove-Item, Get-ChildItem) behave very similarly to before.

Apresentamos a seguir alguns casos de uso das novas funcionalidades:The following shows some use cases of the new capabilities:

NEW-ITEMNEW-ITEM

# Create a new symbolic link file named MySymLinkFile.txt in C:\Temp which links to $pshome\profile.ps1
cd C:\Temp
New-Item -ItemType SymbolicLink -Name MySymLinkFile.txt -Target $pshome\profile.ps1 

# Target is an alias to the Value parameter
# All 3 commands below are equivalent to above
New-Item -ItemType SymbolicLink -Path C:\Temp -Name MySymLinkFile.txt -Value $pshome\profile.ps1
New-Item -ItemType SymbolicLink -Path C:\Temp\MySymLinkFile.txt -Value $pshome\profile.ps1
New-Item -ItemType SymbolicLink -Name C:\Temp\MySymLinkFile.txt -Value $pshome\profile.ps1
# Create a new symbolic link directory named MySymLinkDir in C:\Temp which links to the $pshome folder
# ItemType is the same for files and directories - autodetect based on specified target
cd C:\Temp
New-Item -ItemType SymbolicLink -Name MySymLinkDir -Target $pshome 

# Target is an alias to the Value parameter
# Similar to above, any combination of Path and Name also works
New-Item -ItemType SymbolicLink -Path C:\Temp -Name MySymLinkDir -Value $pshome
New-Item -ItemType SymbolicLink -Path C:\Temp\MySymLinkDir -Value $pshome
New-Item -ItemType SymbolicLink -Name C:\Temp\MySymLinkDir -Value $pshome
New-Item -ItemType HardLink -Path C:\Temp -Name MyHardLinkFile.txt -Value $pshome\profile.ps1
# Same combinations of Path and Name allowed as described above
