I want to be able to tell what path my executing script was run from. This will often not be $pwd. I need to call other scripts that are in a folder structure relative to my script and while I could hard code the paths, that's both distasteful and a bit of a pain in the neck when trying to promote from "dev" to "test" to "production". ...
What Powershell pitfalls you have fall into? :-) Mine are: # ----------------------------------- function foo() { @("text") } # Expected 1, actually 4. (foo).length # ----------------------------------- if(@($null, $null)) { Write-Host "Expected to be here, and I am here." } if(@($null)) { Write-Host "Expected to be her...

Hi, I'm automating the usage of powershell scripts from C# using the powershell async pipeline invoke and I notice that when I execute script over and over again, using the same runspace, the .vhost.exe memory usage goes up and up and up, and it would run out of memory after a days operations. Is there a way to measure how much me...
I'm creating a Powershell script to deploy some code and part of the process is to call a command-line compression tool called RAR.EXE to back-up some folders.

Edit: Changed the question title since the answer explicitly only handles Symlinks. I am having a Powershell script which is walking a directory tree and sometimes I have auxiliary files hardlinked there which should not be processed. Is there an easy way of finding out whether a file (i. e. System.IO.FileInfo) is a hard link or not? I...
NOTE: This is a solution for Project Euler problem 14. If you still want to solve it yourself then don't read on. The problem was to find the number below one million which, as starting number for the Collatz sequence, produces the longest such sequence. My initial code was as follows: $r = @{} for($i = 1; $i -lt 1000000; $i++) { ...

One of the tasks is to use remote WMI to read the registry and find the process owner of explorer.exe in order to determine who is logged in. This seems easy enough g...
As a part of my development I'd like to be able to validate an entire folder's worth of XML files against a single XSD file. A PowerShell function seems like a good candidate for this as I can then just pipe a list of files to it like so: dir *.xml | Validate-Xml -Schema .\MySchema.xsd I've considered porting C# code from the Validati...

Hi, I have a Powershell script that is loading a .NET assembly (.EXE in my case) and calling a public method that uses the app.config to pull an encrypted connection string. The script dynamically copies the assembly's exe.config over to the Powershell ($pshome) folder as powershell.exe.config and is able to run from my development box...
