PowerShell Cheat Sheet

Let’s start with a quick introduction to Windows 10 PowerShell commands.

PowerShell Basics

PowerShell is a cross-platform and a commonly used task automation solution combining the power of the command-line shell, a scripting language, and a configuration management framework. You can run PowerShell on Windows, Linux, and macOS operating systems. Unlike other available shells that only accept and return data, PowerShell accepts and returns .NET objects.

This shell comes with the following features.

  • Robust command-line history
  • Extensive features, like tab completion and command prediction
  • Command and parameter aliases
  • Pipeline for changing commands
  • In-console help system, like Unix man pages

Considering the features of any scripting language, you can use PowerShell to automate the system management process and task. It lets you build, test, and deploy solutions in CI/CD environments.

PowerShell is built on the .NET Common Language Runtime (CLR), which means all the inputs and outputs are .NET objects. You do not have to parse text output to retrieve information from it.

The PowerShell scripting language comes with the following features.

  • Functions, classes, objects, and modules
  • Easy formatting system for providing clear output for enhanced readability
  • Built-in support for different data formats, such as CSV, JSON, and XML
  • Type system for creating dynamic types

Now, let’s get into some useful PowerShell commands.

PowerShell Commands Cheat Sheet


Cmdlets are PowerShell’s internal commands. These cmdlets will return one or more objects to the pipeline where at the end of that pipeline, we mention some properties of the objects in the following table to see their values displayed on the screen.




This command allows you to get support with PowerShell.


This command offers you a list of available PSDrives, such as c, env, hklm, hkcu, alias, etc.


In any registry, children are the subkeys of the current key. To get the required details, you can use the following command.

Get-ChildItem -recurse

Run this command to list all the children recursively of the current PSdrive, folder, or registry key.

Get-ChildItem -rec -force

Use this command To include the hidden folders (directories).

(Get-ChildItem).name or Get-ChildItem -name

Run any of these commands to get the list file and directory names in the current folder.


Use this command to get the number of entries in the collection of objects returned by the Get-Children.


PSdrives are the collection of entities grouped together so they can be accessed as a filesystem drive. The “PSprovider” does this grouping.

By default, a PS session can access several PSdrives including c:, env:, alias:, and HKLM:, where c: refers to the usual Windows c-drive; env: is the space of Windows environmental variables; alias: is the collection of cmdlet aliases; and HKLM is a hive in the registry.

Any PS session will enter the user’s home folder. If you want to switch from a PS session to another PSdrive and retrieve the information from that drive, consider the following commands:



Switching to env-

The prompt character will change to the “ENV:\>”. Set-Location env by running the following command:


Set-Location env-
Env:\> Get-Childitem

This command will get you all the environment variables.

Env:\> Get-Childitem userprofile

Use this command to get the environment variables of “userprofile.”

Env:\> Set-Location alias:

Run the following command to change the prompt character to “Alias.”

Alias:\> Get-Childitem

Run this command to get all the children of all aliases.

Alias:\> Set-Location C:\

Use this command to get the “C:/>” prompt again, back to the default drive.


Run this command to find what alias “ls” stands for.


Cmdlets uses the pipelines to pass the objects but not the character streams like Unix. The pipeline character is | (ASCII 124), followed by a command that handles the output passed through the pipeline. The pipeline consists of the following three stages.

Get-ChildItem *.txt | Where-Object length -lt 1000 | Sort-Object length

The following table highlights some of the basic pipeline commands:



(Get-Item /Users/praashibansal/Desktop).lastwritetime.year

Easily sets the value of the ‘lastwritetime.year’ property to the present date and time without affecting the file’s content.

(Get-ChildItem data.txt.rtf -name).name # -> null

Provides an empty result

"data.txt.rtf" | Rename-Item -NewName "data_new.txt.rtf"

Changes the old file names and file extensions to the new ones

Get-ChildItem data.txt | Rename-Item -new {$}

A trivial renaming command that invokes an automatic variable

Get-ChildItem data.txt.rtf -name | Rename-Item -new {$}

If the piped object $_ doesn't have the member property (name), you will receive an error, as parameter $ is null

Get-ChildItem | Select-Object basename | Sort-Object *

Displays the list of the names of all the files that are present in the current folder sorted in alphabetical order.

Move-Item *.txt subdirectory

Moves all the files to the folder subdirectory

Get-ChildItem *.txt | Move-Item ..\

Gives the error message that Move-Item lacks input


Cmdlets come with several aliases. The following table highlights a few of aliases, along with their descriptions:




Appends value to a file


Finds file content in an array


Changes folder, key, or PS drive


Clears console


Delete files

Get-ChildItem -Path .\

Lists Folder, Key, or PSDrive Children


Sends the array to the console, pipeline, or redirect it to the file


Traverses each object in a pipeline


Formats the table with selected properties for each object in each column


Formats the process properties by name


Provides Cmdlet Alias


Provides you with commands from the current session only


Retrieves all the object members

Get-ItemProperty .\data.txt | Format-List

Provides the specified item’s properties

Get-ItemPropertyValue -Path '.\data.txt' -Name LastWriteTime

Gives the current value for a specified property while using the name parameter

Get-Variable m*

Finds session variable names and sessions

New-Item -Path .\ -Name "testfile1.txt" -ItemType "file" -Value "This is a text string."

Creates a new file, directory, symbolic link, registry key, or registry entry


Gives the entire list of all the running processes


Provides the current directory’s or registry key’s location

Rename-Item -Path “old_name” -NewName “new_name”

Renames the old item name with the new name

Remove-Item .\testfile1.txt

Removes the specified directory, files, or registry keys


Removes the specified variable


Suspends an activity for a specified period of time


  • Arithmetic Operators

Some Other Operators



() Grouping Operator

Allows you to override operator precedence in expressions

&() Subexpression Operator

Gives you the result of one or more statements

@( ) Array Subexpression Operator

Returns the results of one or more statements in the form of arrays.

& Background Operator

The pipeline before & is executed by this command in a Powershell job.

[] Cast Operator

Converts objects to the specific type.

Regular Expressions

A regular expression is a pattern that is used to match text that includes literal characters, operators, and other constructs. PowerShell regular expressions are case-insensitive by default.


Case Sensitivity


use -CaseSensitive switch

switch statement

use the -casesensitive option


prefix with 'c' (-cmatch, -csplit, or -creplace)

  • Character Literals

A regular expression can be a literal character or a string.

  • Character Groups

These allow you to match any number of characters one time, while [^character group] only matches characters NOT in the group.

  • Character Range

A pattern can also be a range of characters. The characters can be alphabetic [A-Z], numeric [0-9], or even ASCII-based [ -~] (all printable characters).

  • Numbers

The \d character class will match any decimal digit. Conversely, \D will match any non-decimal digit.

  • Word Character

The \w character class will match any word character [a-zA-Z_0-9]. To match any non-word character, use \W.

  • Wildcard

The period (.) is a wildcard character in regular expressions. It will match any character except a newline (\n).

  • Whitespace

Whitespace is matched using the \s character class. Any non-whitespace character is matched using \S. Literal space characters ' ' can also be used.

  • Escaping Characters

The backslash (\) is used to escape characters so the regular expression engine doesn’t parse them.

The following characters are reserved: []().\^$|?*+{}.

  • Substitution in Regular Expression.

The regular expressions with the -replace operator allows you to dynamically replace text using captured text.

<input> -replace <original>, <substitute>

Flow Control

  • ForEach-Object

ForEach-Object is a cmdlet that allows you to iterate through items in a pipeline, such as with PowerShell one-liners. ForEach-Object will stream the objects through the pipeline.

Although the Module parameter of Get-Command accepts multiple values that are strings, it will only accept them via pipeline input using the property name, or parameter input.

If you want to pipe two strings by value to Get-Command for use with the Module parameter, use the ForEach-Objectcmdlet:

$ComputerName = 'DC01', 'WEB01'

foreach ($Computer in $ComputerName) {

Get-ADComputer -Identity $Computer

  • For

A “for” loop iterates while a specified condition is true.

For example:

for ($i = 1; $i -lt 5; $i++) {

Write-Output "Sleeping for $i seconds"

Start-Sleep -Seconds $i


  • Do

There are two different “do” loops in PowerShell. Do Until runs while the specified condition is false.

Example 1:

$number = Get-Random -Minimum 1 -Maximum 10

do {

$guess = Read-Host -Prompt "What's your guess?"

if ($guess -lt $number) {

Write-Output 'Too low!'


elseif ($guess -gt $number) {

Write-Output 'Too high!'



until ($guess -eq $number)

Example 2:

$number = Get-Random -Minimum 1 -Maximum 10

do {

$guess = Read-Host -Prompt "What's your guess?"

if ($guess -lt $number) {

Write-Output 'Too low!'

} elseif ($guess -gt $number) {

Write-Output 'Too high!'



while ($guess -ne $number)

  • While

Similar to the Do While loop, a While loop runs as long as the specified condition is true. The difference however, is that a While loop evaluates the condition at the top of the loop before any code is run. So, it doesn't run if the condition evaluates to false.

For example:

$date = Get-Date -Date 'November 22'

while ($date.DayOfWeek -ne 'Thursday') {

$date = $date.AddDays(1)


Write-Output $date


PowerShell allows you to store all types of values. For example, it can store command results and command expression elements like names, paths, and settings. Here are some of PowerShell’s different variables.

  • User-created variables: These are created and maintained by the user. The variables you create at the PowerShell command line will only exist until the PowerShell window is open. When you close the PowerShell window, these variables are deleted. If you want to save a variable, you need to add it to your PowerShell profile. You can create variables and declare them with three different scopes: global, script, or local.
  • Automatic variables: These variables store the state of PowerShell and are created by PowerShell. Only PowerShell can change their values as required to maintain accuracy. Users can’t change these variables’ value. For example, the $PSHOME variable will store the path to the PowerShell installation directory.
  • Preference variables: These variables store user preferences for PowerShell and are created by PowerShell. These variables are populated with default values and can be changed by the users. For example, the $MaximumHistoryCount variable specifies the maximum number of entries in the session history.

To create a new variable, you need to use an assignment statement and assign a value to the variable. There is no need to declare the variable before using it. The default value of all variables is $null.

For example:

$MyVariable = 1, 2, 3



  • Naming Your Function

Use a Pascal case name with an approved verb and a singular noun to name a function. You can get a list of approved verbs by running Get-Verb:

Get-Verb | Sort-Object -Property Verb

  • Creating a Simple Function

Use a function keyword followed by the function name to create a simple function. Then, use an open and closing curly brace. The function will execute code contained within those curly braces.

For example:

function Get-Version {



Working with Modules

A module is a package containing PowerShell members, such as cmdlets, providers, functions, workflows, variables, and aliases. You can implement package members in a PowerShell script, a compiled DLL, or both. PowerShell automatically imports the modules the first time you run any command in an installed module. You can use the commands in a module without setting up or profile configuration.

  • How to Use a Module

To use any module, you need to first install them. Then, find the command that comes with the module and use them.

  • Installing a Module

If you get a module as a folder, install it before you use it on the PowerShell command line. Some modules are preinstalled. You can use the following command to create a Modules directory for the current user:

New-Item -Type Directory -Path $HOME\Documents\PowerShell\Modules

Copy the entire module folder into the Modules directory. You can use any method to copy the folder, including Windows Explorer, Cmd.exe, and PowerShell.

  • Finding the Installed Modules

Run the following to find the modules installed in a default module location (not imported).

Get-Module -ListAvailable

  • Finding Commands in a Module

Run the following command to find a module’s commands:

Get-Command -Module <module-name>

Get-Command -Module Microsoft.PowerShell.Archive

  • Importing a Module

Run the following command with the proper module name:

Import-Module <module-name>
  • Removing a Module Name

You can run the following command with the proper module name:

Remove-Module <module-name>
  • View Default Module Locations

Use the following command to view default module locations:

  • Add a Default Module Location

You can use the following command format:

$Env:PSModulePath = $Env:PSModulePath + ";<path>"
  • Add a Default Module Location on Linux or MacOS

Use the following to execute the same command as above, only with Linux or macOS:

$Env:PSModulePath += ":<path>"

Hash Tables

A hash table is a complex data structure to store data in the form of key-value pairs. We also refer to a hash table as a dictionary or associative array. To understand a hash table, consider a series of IP addresses and the respective computer names. A hash stores this data in the form of key-value pairs, where IP addresses refer to keys and computer names to their corresponding values.

The hash table syntax is as follows:

@{ <name> = <value>; [<name> = <value> ] ...}

An ordered dictionary’s syntax is as follows:

[ordered]@{ <name> = <value>; [<name> = <value> ] ...}
  • Creating Hash Tables

If you want to create a hash table, follow these steps:

  • Start the hash table with an at sign (@) and enclose it in curly braces ({}).
  • A hash table should contain at least one key-value pair, and hence, enter the data after creating a hash table.
  • Separate key from its value using an equal sign (=).
  • Separate the key/value pairs in a hash table with a semicolon (;).
  • Enclose the space between the keys in quotation marks. Values must be valid PowerShell expressions. Also, enclose strings in quotation marks, even if there are no spaces between them.
  • Save a hash table as a variable to manage it efficiently.
  • When assigning an ordered hash table to a variable, place the [ordered] attribute before the @ symbol. If you place it before the variable name, the command fails.

For example:

$hash = @{}

$hash = @{ Number = 1; Shape = "Square"; Color = "Blue"}

[hashtable]$hash = [ordered]@{

Number = 1; Shape = "Square"; Color = "Blue"}


  • Adding and Removing Keys and Values

To add keys and values to a hash table, use the following command format:

$hash["<key>"] = "<value>"

For example, you can add a "Time" key with a value of "Now" to the hash table with the following statement format:

$hash["Time"] = "Now"


$hash.Add("Time", "Now")

Or, you can remove the key with this statement format:


Asynchronous Event Handling

These cmdlets allow you to register and unregister event subscriptions and list the existing subscriptions. You can also list pending events and handle or remove them as desired.

PowerShell eventing cmdlets

Eventing Cmdlet name



This cmdlet registers an event subscription for events generated by .NET objects


Registers an event subscription for events generated by WMI objects


Registers an event subscription for events generated by PowerShell itself


Gets a list of the registered event subscriptions in the session


Removes one or more of the registered event subscriptions


Waits for an event to occur. This cmdlet can wait for a specific event or any event. It also allows a timeout to be specified, limiting how long it will wait for the event. The default is to wait forever.


Gets pending unhandled events from the event queue


Removes a pending event from the event queue


This cmdlet is called in a script to allow the script to add its own events to the event queue
