When you pipeline the parameter Get-Member (alias gm) and filter out properties then there will be two different properties that will be displayed. One is for the File and another is for the Folders.Get-ChildItem propertiesCommandGet-ChildItem | gm | where{$_.Membertype -eq "Property"}Output** Properties of Directory TypeName: System.IO.DirectoryInfo Name              MemberType Definition ----              ---------- ---------- Attributes        Property   System.IO.FileAttributes Attributes {get;set;} CreationTime      Property   datetime CreationTime {get;set;} CreationTimeUtc   Property   datetime CreationTimeUtc {get;set;} Exists            Property   bool Exists {get;} Extension ...

Get-ChildItem (alias: dir) in Powershell is used to get the items inside the container. This container could be the Folders, Registry or the certificate store. You can retrieve items from one or more specified locations. This command works similar to the dir in command prompt but PowerShell provides a modern way to extract the data.

After killing the process using Stop-Process command in PowerShell, you can determine if the process is really terminated from the system with HasExited function.For example, we will kill Notepad process and check if Notepad process still exists in the system?$notepad = Get-Process notepad | Stop-Process if($notepad.HasExited){"Process is terminated"} else{"Process is still running"}

With the Passthru parameter, PowerShell returns the output in the console. For example, below notepad.exe process with ID 12344 will be stopped and the same will be displayed in the console with the Passthru parameter. Earlier it was not the case with only Stop-Process.PS C:\WINDOWS\system32> Stop-Process -Id 12344 -PassThru     Handles  NPM(K)    PM(K)      WS(K)     CPU(s)     Id  SI ProcessName     -------  ------    -----      -----     ------     --  -- -----------         227      13     2800      13440       0.19  12344   1 ...

To get the consent from the user before stopping process or instance, -confirm parameter is used.ExampleIn the below example, we will stop notepad.exe process with –Id 4900 using –Confirm parameter.PS C:\WINDOWS\system32> Stop-Process -Id 4900 -Confirm Confirm Are you sure you want to perform this action? Performing the operation "Stop-Process" on target "notepad (4900)". [Y] Yes [A] Yes to All [N] No [L] No to All [S] Suspend [?] Help (default is "Y"):Similarly, you can use the –Confirm parameter for stopping the process with Name.PS C:\WINDOWS\system32> Stop-Process -Name Notepad -Confirm

To stop the specific instance of the process, Process ID needs to provide to Stop-Process cmdlet.ExampleIn the below example, we need to stop Notepad process with instance ID 25400.OutputHandles  NPM(K)    PM(K)      WS(K)     CPU(s)     Id  SI ProcessName -------  ------    -----      -----     ------     --  -- -----------     228      14     3156      13680       0.13   4900   1 notepad     232      14     3196      13752       0.16  25400   1 notepadStop-Process -Id 25400 Now, when Get-Process command is run, there will be no process running with –Id 25400.CommandPS C:\WINDOWS\system32> Get-Process -Name notepadOutputHandles  NPM(K)    PM(K)      WS(K)     CPU(s)     Id  SI ProcessName -------  ------    -----      -----     ------     --  -- -----------     227      13     2808      13492       0.14   4900   1 notepad

To stop running all the instances of the process in PowerShell Stop-Process command is used. For example, in the below example, we have two running instances of notepad.exe process.CommandPS C:\WINDOWS\system32> Get-Process notepadOutputPS C:\WINDOWS\system32> Get-Process notepad Handles  NPM(K)    PM(K)      WS(K)     CPU(s)     Id  SI ProcessName -------  ------    -----      -----     ------     --  -- -----------     228      13     3160      13448       0.14  15564   1 notepad     228      14     3148      13668       0.17  22644 ...

To get the output in gridview format in PowerShell, you need to Pipeline the Out-GridView variable so the output will be in GUI format.CommandGet-Process | Sort-Object CPU -Descending | Select -First 10 | Out-GridView -Title "Top 10 CPU usage processes"

To display only the first 5 processes you need to use –First parameter in the Select-Object pipeline statement. You can use multiple filter statements and later at last pipeline the –First command to display only a few results.CommandGet-Process | Select -First 5OutputHandles  NPM(K)    PM(K)      WS(K)     CPU(s)     Id  SI ProcessName -------  ------    -----      -----     ------     --  -- -----------     498      26     9736      18624       2.27   6320   1 AcroRd32     624      51   112048 ...

You can group the processes based on their properties. Here, we will group the processes based on their name, it would display how many instances of the process is running. Group-Object command is useful for it.CommandThe below command will group the object and sort the object based on their thread counts.Get-Process |Group-Object Name | Select Name, Count |Sort-Object count - DescendingOutputName                                                           Count ----                                                           ----- svchost                                                           91 chrome                                                            34 RuntimeBroker                                                     11 conhost                                                            6 Code                                                               6 WmiPrvSE                                                           6 dllhost                                                            4 RAVBg64                                                            4 powershell                                                         3 csrss                                                              2 fontdrvhost                                                        2 AcroRd32                                                           2 taskhostw                                                          2 SkypeBridge                                                        1 smartscreen                                                        1 smss                                                               1 sihost                                                             1 SkypeApp                                                           1 SkypeBackgroundHost                                                1 sppsvc                                                             1 StartMenuExperienceHost                                            1
