I want to pass -Unique as parameter for select-string
param(
$y="CAR"
$parameter=""
)
get-childitem -r -i "*.txt"| select-string "TABLE FILE $y" | Select-Object filename,path $parameter
But whenever i try to pass the parameter, i get the following error
powershell : Select-Object : A positional parameter cannot be found that accepts argument '-Unique'.

Also want to pass multiple system key if possible such as -unique -simplesearch -casesensitive
You can't pass a switch as a string parameter like that. You need to use a technique called 'splatting'. See help about_splatting or https://msdn.microsoft.com/en-us/powershell/reference/5.1/microsoft.powershell.core/about/about_splatting

I'm facing an issue of getting all vms configuration ( using Get-ScVirtualMachine command) into an array from an input file.
The code is this one below
$VmsList = Get-Content C:\VmsList.txt
foreach($vm in $VmsList){
$Result += Get-SCVirtualMachine -Name $vm
}
And I have this error
Method invocation failed because [Microsoft.SystemCenter.VirtualMachineManager.VM] does not contain a method named 'op_Addition'.
At line:3 char:1
$Result += Get-SCVirtualMachine -Name $vm
+ CategoryInfo : InvalidOperation: (op_Addition:String) [], RuntimeException

I forgot to declare the array $result = #()
I resolved the issue.
Can someone please explain the following behaviour to me?

If I had a penny for every minute I've wasted on PowerShell's insistance that backticks, quotes and other meta-characters are just right, I would be the richest man on Earth! Somebody please save me from this madness!
And BTW, what I'm actually trying to do is recurse through a bunch of folders and delete everything that isn't a video file, like so...
Remove-Item -Path $filePath -Recurse -Exclude '*.avi','*.mkv','*.mp4'
...which doesn't work for (presumably) the same reason: not being able to pass a variable to the -Path parameter. And if someone is feeling really generous, they could also help me with this. MTIA! :D
Use -LiteralPath instead of -Path because some of the special characters where interpreted with -Path.
Remove-Item -LiteralPath
Special characters are just so much fun in PS right?
-LiteralPath works exactly like Patrick explained, but they don't allow for wildcards; because they're literal.
Have you tried using single quotes ' instead of double quotes ". This allows you to escape special characters, while still evaluating wildcards. Try the commands below:
New-Item -Path 'C:\Users\username\PSScripts\bracket`[\te$t.txt'
Get-Item -Path 'C:\Users\username\PSScripts\bracket`[\*'
Also, if it helps, I use VSCode for most scripting and, if you use tab completion, it will format this properly for you.
I hope that helps!
The solution to my overall problem ended up being this line of my batch script:
powershell -Command "Get-ChildItem -Recurse -LiteralPath %filePath% | Where-Object Extension -match '^(?!(\.avi|\.mkv|\.mp4)$)' | Remove-Item"
The regex was the hardest to get right, since I haven't used negative lookaheads before, but after ~2 hours of total time spent on this one line of code, it finally works!
I just need to call another script and pass the parameters to it.
I tried doing invoke-expression to access it, i tried using &, and nothing worked
I tried doing the following:
$hostfile = "C:\Users\username\Desktop\csvfile_test.csv"
$outFile = ".\testerFile.xlsx"
& '.\organizer.ps1' "-csvFile $hostfile -outputPath $outFile "
Invoke-Expression 'C:\Users\username\Desktop\organizer.ps1' "$hostfile $outFile"
I receive the following errors:.
with ampersand (&):

When you write this:
& '.\organizer.ps1' "-csvFile $hostfile -outputPath $outFile "
you are passing a single parameter to the script (one quoted string). That's not what you want.
This is what you need:
$hostfile = "C:\Users\username\Desktop\csvfile_test.csv"
$outFile = ".\testerFile.xlsx"
.\organizer.ps1 -csvFile $hostfile -outputPath $outFile
First, you don't need the & (invocation) operator because your command name (the organizer.ps1 script in the current location, in this example) doesn't contain spaces. (You can add it if you want, but it's unnecessary in this scenario.)
Second, the -csvFile and -outputPath parameters each require a string.
I want to check if VMHost is configured with Syslog forwarding
I have written the following cmdlets but it is not giving "Syslog forwarding" status.
$esxcli = Get-EsxCli -VMHost abc.com
$esxcli.system.syslog | Select-Object *
$esxcli.system.syslog | gm is returning an error

PowerCLI includes the Get-VMHostSysLogServer cmdlet. In the context of your question, this command would return the Syslog Server for the VMHost abc.com:
Get-VMHostSysLogServer -VMHost abc.com
I've tried two ways to instantiate a class in Powershell v3:
$regex = New-Object -Type System.Text.RegularExpressions.Regex -ArgumentList '\/\/.*' | Get-Member
$regex::Replace("//hey", "")
And:
$netregex = [regex]::new('\/\/.*') | Get-Member
$nosingleline = $netregex::Replace("//hey", '')
The first way yields this:
Unable to cast object of type 'System.Object[]' to type 'System.Type'.
At line:2 char:1
$regex::Replace("//hey", "")
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
CategoryInfo : OperationStopped: (:) [], InvalidCastException

The second way yields this:

Remove | Get-Member from both commands. It is changing the ultimate object type being output on those lines.
Also use . to access the method:
$netregex = [regex]::new('\/\/.*')
$nosingleline = $netregex.Replace("//hey", '')
$regex = New-Object -Type System.Text.RegularExpressions.Regex -ArgumentList '\/\/.*'
$regex.Replace("//hey", "")
