In our previous post we already discussed about “How to check response code from a website using PowerShell“ by using single URL in example. Here let we discuss how to read the list of URLs from the text file and validate the list of URL . Finally script will generate the Excel file with the output result.
$URLListFile = "D:\PowerShell\URLList.txt"
#Reading the list of URLs from the URLList.txt file
$URLList = Get-Content $URLListFile -ErrorAction SilentlyContinue
#Declaring Array
$Result = @()
$FormatGenerater = "<HTML><BODY background-color:grey><font color =""black""><H2> snfcms cert </H2>
</font><Table border=1 cellpadding=0 cellspacing=0><TR bgcolor=gray align=center><TD><B>URL</B>
</TD><TD><B>StatusCode</B></TD></TR>"
Foreach($URL in $URLList)
{
$time = try{
$request = $null
#Measure-Command : Measures the time it takes to run script blocks and cmdlets.
$response = Measure-Command { $request = Invoke-WebRequest -Uri $URL }
$response.TotalMilliseconds
}
catch
{
$request = $_.Exception.Response
$time = -1
}
$result += [PSCustomObject] @{
Time = Get-Date;
Uri = $URL;
StatusCode = [int] $request.StatusCode;
}
}
if($result -ne $null)
{
Foreach($Entry in $Result)
{
if($Entry.StatusCode -ne "200")

To read an array into Read-Host (get the array as input), you would need to put it in a loop because anything entered into Read-Host will be interpreted as a string. To make output in new line we can use $OFS, which is a special variable in PowerShell . OFS stands for Output field separator . You would use this to separate object/Array.
The .split() method is self explanatory, the .trim() method will simply remove leading and trailing spaces and leading and trailing line breaks
Example #1 : Getting Value as an Array by Looping
$arrayInput = @()
do {
$input = (Read-Host "Please enter the Array Value")
if ($input -ne '') {$arrayInput += $input}
}
#Loop will stop when user enter 'END' as input
until ($input -eq 'end')
$arrayInput
OUTPUT:
Example 2# : Alternative approach for handling the multiple inputs without loop.
#Set New line using OFS special Powershell variable
$OFS = "`n"
#Externally set input value as string
[string[]] $_ServerList= @()
#Get the input from the user
$_ServerList = READ-HOST "Enter List of Servers"
#splitting the list of input as array by Comma & Empty Space
$_ServerList = $_ServerList.Split(',').Split(' ')
$OFS + $_ServerList
In this article, Let me show you how to move files from one location to another location using PowerShell script. The Move-Item cmdlet moves an item, including its properties, contents, and child items, from one location to another location. The locations must be supported by the same provider.
Move-Item : Cannot create a file when that file already exists.
Example:1Moving single files/folders
In the PowerShell window, type the command below and press ENTER. After the –path parameter, type the path of the file on your local PC that you want to copy, and after the –destination parameter, type the path of the destination folder. In the example below, I’m moving a file called URL_List.txt from the Source File Path folder to the Destination File Path folder.
Also, by default, Get-ChildItem does not move hidden files. To move hidden files, use the Forceparameter with Get-ChildItem.
Example:3 Moving the files based on File Type (extension)
I had created $_FileType array which contains the list of file types that need to move. After execution, all .html and .txt files will move from source to destination folder. Please refer to the snapshots to under stand the before and after the script execution
#location of starting directory
$_sourcePath ="C:\Users\dotnet-helpers\Desktop\SourcePath"
#location where files will be copied to
$_destinationPath = "C:\Users\dotnet-helpers\Desktop\DestinationPath";
#Array of extension that need to move from source path
$_FileType= @("*html*", "*.*txt")
Get-ChildItem -recurse ($_sourcePath) -include ($_FileType) | move-Item -Destination ($_destinationPath)
OUTPUT:
Before Execution: Source Folder/Destination Folder
After Execution: Source Folder/Destination Folder

I hope you have an idea of how to move the files from one location to another location using the Powershell script. I would like to have feedback from the readers of my posts. Your valuable feedback, question, or comments about this article are always welcome.
I hope you have idea of how to use KnockoutJS visible or hidden based on the value passed in the binding. I would like to have feedback from my posts readers. Your valuable feedback, question, or comments about this article are always welcome.
The text binding causes the associated DOM element to display the text value of our parameter. This is used in text-level DOM elements such as div,span. The text binding accepts any data type and parses it into String before rendering it.
Syntax:
text: <binding-value>
Parameters
Knockout sets the element’s content to a text node with your parameter value. And if there is any previous content then it will be overwritten.
If this parameter is an observable value, then the binding value will update the element’s text whenever the value changes. If the parameter isn’t observable then it will only set the element’s text once and will not update again.
I hope you have idea of Controlling text and appearance. I would like to have feedback from my posts readers. Your valuable feedback, question, or comments about this article are always welcome.
In this post we will discuss about how to check the response code from a website. In this article, we’re going to cover how to build a PowerShell function that will query a specific URL and attempt to find out if that URL is working fine or not. To get started, let’s construct a function for this task called CheckSiteURLStatus with a single parameter called URL.
Net.WebReques makes a request to a Uniform Resource Identifier (URI). This is an abstract class.
Using Net.WebRequest class (which is under the System.Net namespace), we get a response from a web server. Unlike the Net.WebClient class, you will not be able to download the site page. However, using Net.WebRequest class, you can get a response code and also see what type of web server is being used to host the site. The WebRequest class has a static method called Create in which we can pass a URL to invoke a HTTP, We’ll add the code to create the request into our function as shown below.
[string] $_URL = 'https://dotnet-helpers.com'
function CheckSiteURLStatus($_URL) {
try {
$request= [System.Net.WebRequest]::Create($_URL)
$response = $request.getResponse()
if ($response.StatusCode -eq "200") {
write-host "`nSite - $_URL is up (Return code: $($response.StatusCode) -
$([int] $response.StatusCode)) `n" -ForegroundColor green
}
else {
write-host "`n Site - $_URL is down `n" ` -ForegroundColor red
}
} catch {
write-host "`n Site is not accessable, May DNS issue. Try again.`n" ` -ForegroundColor red
}
}
CheckSiteURLStatus $_URL
Based on the response code, the condition will execute and write on the console.Finally, we’ll need to dispose of the response after we’re done to clear it from memory which would finish it off to make it look like this:

One of the great benefits of PowerShell is its pipeline mechanics that enable the output of one command to be passed to the next command in the pipeline. That output is not sent as basic text but rather the actual objects generated from a command are sent in the native object format to the next command and this is enabled for all commands.
Example: 1
If you open a PowerShell window and type the following commands the result is the same for both, Let us test this by the below cmdlet.
If we look at the above script, it like they are the same but in reality, they are working in very different ways. Let us discuss more to understand this more.
Example: 2
From Example 1, we think that it seemed to achieve the same result for both Write-Output and Write-Host but we have differences between these two cmdlets. This can be demonstrated in more detail in this example. Write-Output sends the output to the pipeline. From there it can be piped to another cmdlet or assigned to a variable. Write-Host sends it directly to the console
From the above example, we can able see the Write-Output cmdlet has passed the value to the next process but Write-Host just directly writes to the host and nothing has to send forward to the next cmdlet.
In simpler, if you possibly want to write data to the screen, but also want the data to be passed down the pipeline to further commands, then use Write-Output. Write-Host does not output data to PowerShell Object flow Engine but rather, as the name implies, writes directly to the host and sends nothing to the PowerShell engine to be forwarded to commands later in the pipeline.
Here’s we can discuss on how to add text to the end of a text file using the Add-Content cmdlet using PowerShell. In our example let’s add “This is the last line” to the end of a file using add-content cmdlet to append data to a text file.
Add-Content "C:\dotnet-helpers\DummyfiletoDelete.txt" "This is the last line"
The above example above adds the text to the last line of the text, it doesn’t actually create a new line. We can use an escape character to tell PowerShell to add a carriage return, new line… while appending the text in existing file.
Escape characters:
‘n — New line ‘t — Horizontal tab ‘’ — Single quote ‘” — Double quote ‘0 — Null ‘a — Alert ‘b — Backspace ‘r — Carriage return
Append Text using Escape characters:
Add-Content -Path "C:\dotnet-helpers\DummyfiletoDelete.txt" -Value "`r`nThis is the last line".
The above example append the “This is the last line” as a new line at end of the text file with help of ‘n and’ r
Add-Content -Path "C:\dotnet-helpers\DummyfiletoDelete.txt" -Value "This is the last line added from $env:computername system"
PowerShell offers a number of different ways to manage the variety of text files. Here we learn how to retrieve text from text files and how to find text in text files, all through PowerShell cmdlets.
How To Retrieve Text From Text Files
You can use the powershell Get-Content cmdlet which is used to retrieve all text from a text file specified by the Path parameter.
Executing the above cmdlet, You’ll see that the result was the entire contents of TestFile.txt. If you just wanted to see a particular line number? By default, Get-Content reads all the line in a text file and creates an array as its output with each line of the text as an element in that array.In this case, the array index number is equal to the text file line number. So we can get the each line of the txt file by using the array index number.
IsPublic IsSerial Name BaseType
-------- -------- ---- --------
True True Object[] System.Array
This is test text file
Thanks for reading this posts.
In the above example, the result of Get-Content is a type of System.Array and that by using index numbers in brackets you can get the value of text file. The index is start from Zero.
How To Find Text In Text Files
There are a many different ways to do this but the we can use Where-Object cmdlet which will be the easilest way. The Where-Object cmdlet is a popular cmdlet that allows you to “filter out” various information from the output of other cmdlets. When using Where-Object we must use the $_ variable and this is a special variable in PowerShell known as the pipeline variable.
