I would like to have some kind of setup Cmdlet where the user will be prompted for an Uri, username and password to the REST API and then call Cmldlets like Get-Item without having to enter those parameters.

问题 Some background: I work in a lab environment and have a number of issues that come through that require VHDs to be created and attached to VMs for stress testing.

问题 I've been writing some utilities that make use of PowerShell Cmdlets for App-V. The interesting part is Microsoft seems to only document the cmdlets and not the .net assemblies used behind the Powershell modules. Now I'm familiar with P/Invoke and COM Interop and I've learned how to use System.Management.Automation to create a powershell session and invoke the cmdlets. But something doesn't smell right to me. I'm basically writing my own wrapper classes to hide the powershell invocations from

Is there a way to add Alias to Powershell Cmdlet programmatically?

阅读更多关于 Is there a way to add Alias to Powershell Cmdlet programmatically?

I am writing custom Powershell cmdlets for my application and I need to provide Aliases to some cmdlets. So lets say I have cmdlet Get-DirectoryListing and I want to add Alias (say 'gdl') to this cmdlet. How can I do this?

Is it possible to programmatically add multiple aliases to a cmdlet? You need to create a psm1 file ( powershell module ) where you specific your dll with yours cmdlets to load and add aliases in

How do I move files from an old folder structure to new?

阅读更多关于 How do I move files from an old folder structure to new?

I want to modify my existing folder structure. I had a file tree that was organized in the following way: Client Name State/Province City Order Number But I have modified it to add an address before the order number separated by a hyphen, as such: Client Name State/Province City Order Number - Address I created the new folder structure with a macro I had that generated the original, and I figured this was much easier than renaming the existing folders. So now I want to upload the empty folders to my server, but before I do that I want to take the files from all the old structure and put them
