Important PowerShell commands

PowerShell attracted the attention of many IT executives after its introduction. Windows PowerShell eliminates the need for professionals to lack a complete command-line environment in Windows.

Commands in PowerShell have two versions of alias commands and command-lets, in which most Allies commands are very similar to Linux commands.

For example, the ps command, which is used in Linux to get a list of active processes, is also used in PowerShell.

Before you start working with PowerShell, there are a few important points that we will mention.

Tips for working with PowerShell Commands

– All complete PowerShell commands have a pseudonym.

– When working with PowerShell, uppercase and lowercase letters are no different.

– Copying several lines is possible by selecting the mouse and pressing the Enter key, and to paste, you only need to right-click the mouse.

– When working with PowerShell, you only need to type part of the command and press the Tab key to continue writing it automatically.

– PowerShell can be run and managed on all parts of Windows.

– Other Microsoft software and tools that are not on Windows by default have external modules to add to PowerShell.

– PowerShell has a feature called PowerShell Direct to remotely control and manage another Windows system.

– PowerShell has the ability to execute script commands.

In the following tutorial, you will learn more about the important PowerShell commands.

Learn PowerShell Basic Commands

Get Help commands in PowerShell

Like any PowerShell command line environment, it has a command to get-help. Learning these types of commands will definitely help you a lot in continuing to work with PowerShell.

For example, if you want to get information from the stop-process command, the command you need must be entered as follows.

Get-help stop-process

You can also use the Man command to get help in PowerShell. This command, which is similar to the Man command in Linux, will give you complete information about a command.

This command is entered as follows:

Man stop-process

The difference between the Get-help command and the Man command is that the page stops automatically when the output of the Man command is displayed.

This means that if the output content is more than the page size, it will automatically prevent the continuation of the content so that the user can easily read the text and view the rest with the Enter or Space key.

If you have trouble reading the help commands, you can use the -example parameter to get an example of the command.

In the box below is an example of using -example:

PS C:\Windows\system32> Get-Help Copy-Item -Examples    NAME  Copy-Item    SYNOPSIS  Copies an item from one location to another.    Example 1: Copy a file to the specified directory    PS C:\>Copy-Item "C:\Wabash\Logfiles\mar1604.log.txt" -Destination "C:\Presentation"    This command copies the mar1604.log.txt file to the C:\Presentation directory. The command does not delete the  original file.

If the Get-Help command does not show you complete information about the commands, update the PowerShell help file by entering the following command:

Update-help

Note: If Update-help encounters an error, open your PowerShell as Run as Administrator.

List of files and directories

The next command in this tutorial is the Get-Childitem command. This command is used to get a list of files and folders.

Using this command is very simple and you just need to enter it without parameters in PowerShell.

PS C:\> Get-childitem  Directory: C:\    Mode LastWriteTime Length Name  ---- ------------- ------ ----  d----- 8/8/2017 8:36 PM Intel  d----- 3/19/2017 12:33 AM PerfLogs  d-r--- 8/27/2017 9:10 PM Program Files  d-r--- 8/9/2017 12:47 AM Program Files (x86)  d-r--- 8/8/2017 7:44 PM Users  d----- 8/9/2017 1:13 AM Windows

There is another command called ls that you will enter to get the same output as the Get-Childitem command.

The ls or Get-Childitem command has a commonly used parameter called -attribute. Using this parameter you can see the complete list of hidden files.

Ls -attibutes hidden

or

Get-childitem -attributes h

or

ls -Attrib h

Navigate between folders in PowerShell

The command to change the address in PowerShell is Set-Location. You can also use the Cd command to move between directories.

Set-Location command structure

Set-location D:\multimedia

or

Cd c:\windows

One of the advantages of PowerShell and the Set-Location command is that you can go to the Windows registry directories, with which you can edit the registry keys.

To go to the Windows registry, you must use the -path parameter and the abbreviation of the registry directory.

Set-location -path “HKCU”

After entering the above command, you will go to the HKEY Current User directory.

Clear the PowerShell page

In PowerShell you can use the cls or clear command to clear the page.

Cat eldernode.txt

Get-content eldernode.txt

Copy files in PowerShell

To get a copy in PowerShell, just use one of the Cp, Copy or Copy-Item commands. These 3 commands work the same and are no different.

Copy-Item command structure in PowerShell

Cp D:\multimedia\learn.mkv -destionation E:\video\

or

Copy-item D:\multimedia\learn.mkv -destination E:\video\

Note: In all commands, such as a copy that has two source and destination addresses, you only need to show them with a space.

Rename files in PowerShell

Renaming a file or folder in PowerShell is possible with either Ren or Rename-Item. To rename a file or folder, just type the command and then enter the name of the original file and then a new name with a space.

Rename-item “learn.mkv” train.mkv

or

Ren “learn.mkv” train.mkv

Delete files in PowerShell

Deleting a file or folder in PowerShell is no different, and both can be done using either the Remove-item or Del commands.

Remove-Item command structure in PowerShell

The Move-Item or Mv command can be used to move the file in PowerShell. This command is the same as the structure of the Copy-Item command.

List of active processes in PowerShell
