A String, Arrays, | and a Where-Object

[danield]

I’m getting a String (cant change the type only content) and would like to filter the output of Get-Cluster based on these values

Blockquote
$filter = “'one”,“two”

The length of the string can be anything between one or unlimited

Blockquote
$AllClusters=get-cluster -Domain $domain

What I need help with is the filter condition based on the input.

DanielD64,
Welcome back to the forum. … long time no see.

When you post code, sample data, console output or error messages please format it as code using the preformatted text button ( </> ). Simply place your cursor on an empty line, click the button and paste your code.

Thanks in advance

Could you please elaborate a little more detailed? How does $filter relate to the Get-Cluster command? … and where is your Where-Object?

[danield]

The basic idea I have - but not working is:

$filter = “'one”,“two”
$cluster_filter_array= $cluster_filter.Split(",")

$filterConditions = @()

foreach ($filter in $cluster_filter_array) {

    $filterConditions +=  { $_.Name -like $filter } 

}

$Clusters = @()

foreach ($condition in $filterConditions) {
    $Clusters += $AllClusters | Where-Object -FilterScript $condition
}

Now with formatting

It might be better when you explain what your idea is instead of showing confusing code.

@danield

$filter = “'one”,“two”
$cluster_filter_array= $cluster_filter.Split(",")

1. Where do you define $cluster_filter?
2. If you define a proper array with $filter = “'one”,“two” you don’t have to split it.

@danield

$filterConditions = @()

That’s usually unnecessary.

@danield

foreach ($filter in $cluster_filter_array) {
    $filterConditions +=  { $_.Name -like $filter } 
}

1. If you use a foreach() loop you define a loop variable you name yourself. You don’t have the default pipeline variable $_ in this case.
2. You use the same name for your loop variable like you did before for your array.

@danield

$filterConditions += { $_.Name -like $filter }

What do you expect from this line of code? If you run a comparison you get a $true or a $false. Is it really that what you want to collect in an array?

@danield

foreach ($condition in $filterConditions) {
    $Clusters += $AllClusters | Where-Object -FilterScript $condition
}

Where do you populate $AllClusters?

Please keep in mind that we cannot see your screen and we cannot read your mind. Take a step back and a deep breath and try to explain in simple terms what you want to achieve.
