Update on non-Windows Platforms A lot has changed since this answer was first written. Modern versions of PowerShell are based on .net core, and run cross-platform. The underlying type that enables this whole answer is called [securestring] and the security and encryption that backs it comes from the Data Protection API (DPAPI) on Windows, which … Read more
Keith’s answer also works for Invoke-Command, with the limit that you can’t use named parameters. The arguments should be set using the -ArgumentList parameter and should be comma separated. $sb = { param($p1,$p2) $OFS=’,’ “p1 is $p1, p2 is $p2, rest of args: $args” } Invoke-Command $sb -ArgumentList 1,2,3,4 Also see here and here.
After searching internet on this topic I’ve found a handful of solutions. All of them are hand parsing of file data so I gave up trying to make standard cmdlets to do the job. There are fancy solutions as this which support writing scenario. There are simpler ones and as far as I need no … Read more
With PowerShell 2.0, you can use the built in Cmdlet Add-Type. You would just need to specify the path to the dll. Add-Type -Path foo.dll Also, you can use inline C# or VB.NET with Add-Type. The @” syntax is a HERE string. C:\PS>$source = @” public class BasicTest { public static int Add(int a, int … Read more
They’re different commands for different purposes. The ForEach-Object cmdlet is used in the pipeline, and you use either $PSItem or $_ to refer to the current object in order to run a {scriptblock} like so: 1..5 | ForEach-Object {$_} >1 >2 >3 >4 >5 Now, you can also use a very similiar looking keyword, ForEach, … Read more
In PowerShell 2.0 you can use a script block ({ some code here }) as delegate: $MatchEvaluator = { param($m) if ($m.Groups[“val”].Value -eq “;”) { #… } } $result = $r.Replace($input, $MatchEvaluator) Or directly in the method call: $result = $r.Replace($input, { param ($m) bla }) Tip: You can use [regex] to convert a string … Read more
If you’re after a one-liner you can pipe each csv to an Import-Csv and then immediately pipe that to Export-Csv. This will retain the initial header row and exclude the remaining files header rows. It will also process each csv one at a time rather than loading all into memory and then dumping them into … Read more
Simply use the return instead of the continue. This return returns from the script block which is invoked by ForEach-Object on a particular iteration, thus, it simulates the continue in a loop. 1..100 | ForEach-Object { if ($_ % 7 -ne 0 ) { return } Write-Host “$($_) is a multiple of 7” } There … Read more
The error message is giving you most of what you need. This isn’t just about the TrustedHosts list; it’s saying that in order to use an IP address with the default authentication scheme, you have to ALSO be using HTTPS (which isn’t configured by default) and provide explicit credentials. I can tell you’re at least … Read more
& “C:\Program Files\Automated QA\TestExecute 8\Bin\TestExecute.exe” C:\temp\TestProject1\TestProject1.pjs /run /exit /SilentMode or [System.Diagnostics.Process]::Start(“C:\Program Files\Automated QA\TestExecute 8\Bin\TestExecute.exe”, “C:\temp\TestProject1\TestProject1.pjs /run /exit /SilentMode”) UPDATE: sorry I missed “(I invoked the command using the “&” operator)” sentence. I had this problem when I was evaluating the path dynamically. Try Invoke-Expression construction: Invoke-Expression “& `”C:\Program Files\Automated QA\TestExecute 8\Bin\TestExecute.exe`” C:\temp\TestProject1\TestProject1.pjs /run /exit /SilentMode”
