I want to select the second/third/forth object of a Get-ChildItem statement in my PowerShell script. This gives me the first:

$first = Get-ChildItem -Path $dir |
         Sort-Object CreationTime -Descending |
         Select-Object -First 1

This gives me the first three:

$latest = Get-ChildItem -Path $dir |
          Sort-Object CreationTime -Descending |
          Select-Object -First 3

I would like to get the second, or the third, or the fourth. (NOT the first two and so on).

Is there a way?

For selecting the n-th element skip over the first n-1 elements:

$third = Get-ChildItem -Path $dir |
         Sort-Object CreationTime -Descending |
         Select-Object -Skip 2 |
         Select-Object -First 1

or select the first n and then of those the last element:

$third = Get-ChildItem -Path $dir |
         Sort-Object CreationTime -Descending |
         Select-Object -First 3 |
         Select-Object -Last 1

Beware, though, that the two approaches will yield different results if the input has less than n elements. The first approach would return $null in that scenario, whereas the second approach would return the last available element. Depending on your requirements you may need to choose one or the other.

Select-Nth Element : PowerShell, Trying to may a cmdlet to select the Nth Element in an Array. It doesn't appear Select-Object has a built in way to do this, but the logic isn't … Must be a number. The first element has the index number 1. even: Selects each even child element: odd: Selects each odd child element: formula: Specifies which child element(s) to be selected with a formula (an + b). Example: p:nth-child(3n+2) selects each 3rd paragraph, starting at the 2nd child element

The second approach suggested by @AnsgarWiechers can easily be turned into a simple reusable funtion, like so:

function Select-Nth {
    param([int]$N) 

    $Input | Select-Object -First $N | Select-Object -Last 1
}

And then

PS C:\> 1,2,3,4,5 |Select-Nth 3

.eq(), The result of this call is a red background for item 3. Note that the supplied index is zero-based, and refers to the position of the element within the jQuery object,� With :nth-child(n), all children are counted, regardless of what they are, and the specified element is selected only if it matches the selector attached to the pseudo-class. With the .eq( n ) call only the selector attached to the pseudo-class is counted, not limited to children of any other element, and the (n+1)th one (n is 0-based) is selected.

You could also access the element as an array item, using the index n-1. This seems more succinct than chaining pipes.

$third = (Get-ChildItem -Path $dir | Sort-Object CreationTime -Descending)[2]

.nextAll(), Given a jQuery object that represents a set of DOM elements, the .nextAll() If we begin at the third item, we can find the elements which come after it: Locate all the paragraphs after the second child in the body and give them a class. Options. A traditional <select> box contains any number of <option> elements. Each of these is rendered as an option in the dropdown menu. Select2 preserves this behavior when initialized on a <select> element that contains <option> elements, converting them into its internal JSON representation:

First Item

gci > out.txt
Get-Content out.txt | Select -Index 7 | Format-list

Second Item

gci > out.txt
Get-Content out.txt | Select -Index 8 | Format-list

The item between n and p

$n=3 
$p=7
$count = 0
$index = $n+7
$p=7+7
while($true){ 
   $index = $index + $count
   Get-Content out.txt | Select -Index $index | Format-list
   if($index -eq $p)
   {    
      break;
   }
   $count = $count + 1 
}

<select>, The HTML select element represents a control that provides a menu 3. <select name="pets" id="pet-select">. 4. <option value="">--Please The following example creates a very simple dropdown menu, the second option of which is selected by default. <object> � <ol> � <optgroup> � <option> � <output>. While what you have works, the most straightforward way would be to use the array's index and reference the second item (at index 1 since the index starts at zero for the first element): pkgratio[1] Console.WriteLine(pkgratio[1]); A more complete example:

Indexed collections, This includes arrays and array-like constructs such as Array objects and TypedArray objects. Skip to main content; Select language; Skip to search You can refer to the first element of the array as myArray[0] , the second element of the let cats = ['Dusty', 'Misty', 'Twiggy'] console.log(cats.length) // 3� Here, an un-classed h3 element is inserted between the first and second h3.A elements. In this case, no 2nd color (i.e. orange) appears, and the 3rd color (i.e. green) shows up on the 2nd instance of h3.A .

Vector Indexing, Vector Indexing. An important aspect of working with R objects is knowing how to “index” them Indexing means selecting a subset of the elements in order to use� The contents of the file can change, but I know that I always want to get the second input element with the id attribute "search_query". I need an XPath expression to do this. I tried //input[@id="search_query"][2] but that does not work. Here is an example XML string where this query failed:

11. Lists — How to Think Like a Computer Scientist: Learning with , The values that make up a list are called its elements, or its items. We will use the term The second is a list of three strings. In the second case, they refer to the same object. We can select an entire row from the matrix in the usual way:. Adds an element to the collection of option elements for this select element. HTMLSelectElement.blur() Removes input focus from this element. This method is now implemented on HTMLElement. HTMLSelectElement.checkValidity() Checks whether the element has any constraints and whether it satisfies them.
