Get-Content cmdlet in PowerShell is useful for retrieving the contents of the file or the function. This cmdlet is introduced in PowerShell 3.0. When a file is read by this cmdlet, it reads one line at a time and finally returns the whole content as a collection of objects.SyntaxGet-Content    [-ReadCount ]    [-TotalCount ]    [-Tail ]    [-Path]    [-LiteralPath]    [-Filter ]    [-Include ]    [-Exclude ]    [-Force]    [-Credential ]    [-Delimiter ]    [-Wait]    [-Raw]    [-Encoding ]    [-AsByteStream]    [-Stream ]    []

Recycle bin in Windows operating system is to store the soft-deleted data. Soft deleted data means, data that is not deleted with (SHIFT + DEL) button but simply deleted with DEL button. Each local disk has its own configured recycle bin space.To delete the recycle bin data using GUI, you can simply right click and delete the content.It is also possible to delete the recycle bin content with the PowerShell command with the Clear-Recyclebin cmdlet. This command is introduced in PowerShell 5 and available in newer versions as well.ExampleClear-RecycleBinOutputPS C:\WINDOWS\system32> Clear-RecycleBin Confirm Are you sure you want to perform this action? Performing the operation "Clear-RecycleBin" on target "All of the contents of the Recycle Bin". [Y] Yes  [A] Yes to All ... Read More

When the break statement is mentioned with the Label, PowerShell exits to the label instead of exiting the current loop.Example$i = 1 while ($i -lt 10) {    Write-Output "i = $i"    if($i -eq 5){       Write-Output "Break statement executed"       Break :mylable    }    $i++ } Write-Output "Entering to another loop" $j = 1 :mylable while($j -lt 3){    Write-Output "j = $j"    $j++ }Outputi = 1 i = 2 i = 3 i = 4 i = 5 Break statement executed Entering to another loop j = 1 j = 2As you can see in the above example when the value of 5 executed, the block containing label (mylable) is also executed and execution moves to another loop.

In Switch command, when the single value passed and if it matches the condition then the loop gets automatically exited but when there are multiple values passed and if the value matches the first condition and if you want to terminate the loop then you can use the Break statement. An example is given below.ExampleSwitch (3,5){    1 {"This is One"}    2 {"This is Two"}    3 {"This is Three"; Break}    4 {"This is Four"}    5 {"This is Five"; Break} }OutputThis is ThreeYou can notice in the above output that second parameter 5 won’t be executed because the 3 has already been executed with the break statement.

You can use the break statement with both the While loop and the Do-While loop.To use the Break with a while loop, see the example below.Example$i = 1 While($i -ne 10){    Write-Output $i    if($i -eq 5){break}    $i++ }Output1 2 3 4 5In the above example, the loop terminates when the value of the variable $i reaches 5 because the Break statement is executed.You can also use the break in the nested While loop, here we will take two examples of the nested loop. First when the break is placed outer loop and second when the break is placed in the inner ... Read More

To use the ToSesssion ... Read More

To copy the contents of the folder to the destination folder in PowerShell, you need to provide the source and destination path of the folder, but need to make sure that you need to use a wildcard (*) character after the source path, so the entire folder content gets copied.If you provide only source folder without (*), only folder name gets copied without its contents. We also need to make sure both source and destination folder exists.ExampleCopy-Item -Path D:\Temp\ -Destination D:\TempContent -PassThruOutputWhen you use the above command, you will see the output will be none, because there is no (*) ...
