Other properties of items by using Where-Object. You can perform complex filtering based on Parameters, but those are typically based only on name. Get-ChildItem can filter items with its Path, Filter, Include, and Exclude (This can take an extremely long time to complete.) To list everything on the Cĭrive: Get-ChildItem -Path C:\ -Force -Recurse In order to show contained items, you need to specify the -Recurse The command lists only the directly contained items, much like using Cmd.exe's DIR command or

For example, this command displays the directĬontents of Windows PowerShell Drive C (which is the same as the Windows physical drive C): Get-ChildItem -Path C:\ -Force Add the optionalįorce parameter to display hidden or system items. You can get all items directly within a folder by using Get-ChildItem. Listing All the Files and Folders Within a Folder With specific file and folder manipulation tasks using PowerShell. Manipulating files and folders on Windows physical disk drives.

I think this will make a good addition to the PSScriptTools module so look for an update in the next few weeks.Navigating through Windows PowerShell drives and manipulating the items on them is similar to The difference object, $b, is missing the property “tabitha”, for example. The results are all relative to the difference object. The function generates one type of object by default.īut I also wanted to offer alternatives that would give Gladys information she might want quickly. Write-Verbose "$Name not found in the difference object" Function Compare-PropertyName #foreach #find missing reference properties from the difference object Of course, I want to create a meaningful result so that Gladys can tell at a glance how things compare. } #foreach #find missing reference properties from the difference object #find extra properties in the difference object Then I can go through each list and see what properties are missing or extra. It is easy then to create a list of property names for the reference and difference objects. We’re going to use the Properties property. In this case, we’re going to use a ubiquitous property called PSObject. But sometimes, we need to get our hands dirty. NET sausage-making so you only have to work with the final results. PowerShell goes to a lot of effort to make it easy to use for IT Pros.
All we need is one item to analyze because the property names are the same for objects. To compare object property names, we don’t need the entire object. We even don’t really care about the order of property names because one we have an object we’re going to reference by property name, not its position in the CSV header. In looking at the data you can see the $B is missing “tabitha” and has extra properties “agatha” and “gladys”. my purposes $A is the reference object and the $B is the difference object. Let me start by generating some sample data. The bottom line is that we should look at this as an object comparison problem, not a file problem. You might be creating objects to compare through some other mechanism. Gladys can import her CSV files and turn them into custom objects. Think ObjectsĮven though we’re starting with CSV files, we’re really talking about objects. Does this CSV file have the same property names as that CSV file? Are there extra properties? Or is something missing? So let’s see how we might address this. Her use-case is to compare property names.
In Gladys’ situation, she imports data from CSV files which she processes through her scripts to get things done.
