When it comes to running commands on Windows, PowerShell has become something pretty ace in the hole. For years, enthusiasts were confined to the Windows command line, but in 2006 PowerShell became a powerful alternative. What is Windows PowerShell? PowerShell is an interactive command-and-line interface (CLI) and automation engine developed by Microsoft to develop system configurations and automate administrative tasks. This tool has its own command line with a unique programming language similar to Perl. PowerShell was originally designed to control objects on users' computers. Today, PowerShell offers users an extensive environment where they can perform and automate system management tasks. Users can access resources from Active Directory to Exchange Server through one program. At its core, PowerShell allows the user to access: Command Prompt PowerShell Commands .NET Framework API Windows Management Instrumentation Windows Component Object Model As PowerShell has become an open source application, Linux users and Unix can now access this universal platform. PowerShell is mainly used to help users automate administrative tasks. Instead of performing tedious and repetitive tasks, the user can simply create scripts and issue commands, and PowerShell will perform them automatically. The user can set up hundreds of commands called cmdlets. The List of PowerShell Commands Here are 25 major PowerShell commands: Command nameAliasDescription Set-Locationcd, chdir, slSets the current working location in the specified location. Get-Contentcat, gc, typeGets item content at specified location. Add-ContentacAdds content to these items, such as adding words to a file. SetContentcWrites or replaces content in the item with new content. Copy-Itemcopy, cp, cpiCopies element from one place to another. Delete-Itemdel, erase, rd, ri, rm, rmdirDeletes specified items. Move-Itemmi, travel, mvMoves item from one place to another. Set-Itemsi Changes the value of an item to the value specified in the team. New-Itemni Opens a New Element. Start-JobsajbStarts background job Windows PowerShell. Compare-Objectcompare, difCompares two sets of objects. Group-ObjectgroupGroups objects that have the same value for certain properties. Invoke-WebRequestcurl, iwr, wgetGets content from a web page on the Internet. Measure-ObjectmeasureCalculates numerical properties of objects, as well as symbols, words and lines in rows of objects such as files ... Resolve-PathrvpaResolves symbols wildcards along the way, and displays the contents of the path. Summary-JobrujbRestarts suspended the set-Variableset job, svSets value variable. Creates a variable if it doesn't exist with the requested name. Show-Commandshcm Creates Windows Commands in the team's graphics box. Objects sort-ObjectsortSorts by property values. Start-ServicesasvStarts one or more stopped services. Running-Processsaps, startStarts one or or processes on your local computer. Suspend-JobsujbTemporarily stops workplaces. Wait-JobwjbSuppresses team query until one or all windows PowerShell background jobs running in the session will not be ... Where is the object?, where selects objects from the collection based on their property value. Write-Outputecho, writeSends specified objects to the next team in the pipeline.

How to use Windows PowerShell PowerShell is ideal for corporate administrators who manage complex management operations on large corporate networks. Instead of collecting information about hundreds of different servers and services manually (which will take a long time), you can simply run the script on PowerShell to automatically feed the information back to you. Generally speaking, PowerShell is most profitable for users who have previous experience with command strings. To use PowerShell, you can run a variety of cmdlets, scripts, executables, and .NET classes. For the purposes of this article, we're basically going to focus on cmdlets and scripts to help you get through the basics. Udemy has a number of courses with the highest rating on PowerShell that you may find useful. PowerShell vs. Team Operational for many users, PowerShell is the best alternative to Command Prompt. The reason is that it just has more horsepower. One of the biggest differences is that PowerShell uses cmdlets, not commands. Cmdlets place registry management and Windows Management tools in the administrative reach of users. In contrast, Command Prompt is limited to much simpler commands. There is some crossover in the syntax between the two platforms as PowerShell will take some command of team prompts like ipconfigtocd. However, they are known as pseudonyms rather than cmdlets. Another key difference is that PowerShell focuses on objects. Each part of the data output from the cmdlet is an object, not a text. This makes it easier for the user to navigate on complex data. Incorporating the .NET structure also allows PowerShell scripts to use .NET interfaces. In short, PowerShell is a command prompt on steroids. Download PowerShell Before you delve into the basics of using PowerShell, you first need to access the main interface. If you're a Windows 10 user, you'll already have access to PowerShell 5. Windows 8-8.1 users have access to PowerShell 4, but if you're on Windows 7, you need to install it within .NET. In all operating systems, PowerShell offers two different interfaces. More is an integrated script environment that acts as a comprehensive GUI for experienced users. The main alternative is the PowerShell console, which provides a command line for the user enter their teams. Beginners are advised to stick to the latter until they learn the basics of PowerShell. In order to start PowerShell on Windows 10, you need to be an administrator. Log in as an administrator, click start and scroll through apps until you find Windows PowerShell. Click the right button and select Run as an administrator. On Windows 8.1, just look for PowerShell in the System folder. Similarly, on Windows 7 the default directory for PowerShell is the Accessory folder after the program is installed. As a run of Cmdlets In a nutshell, cmdlet is a single command function. You type cmdlets into the command line just like you would with a traditional command or utility. Cmdlets are the main way to interact with CLI. In PowerShell, most cmdlets are written on C- and consist of instructions designed to perform a function that returns the .NET object. More than 200 cm can be used in PowerShell. The Windows PowerShell command query is not sensitive to cases, so these commands can be typed in the upper or lower case. The main cmdlets are listed below: Get-Location - Get the current Set-Location directory - Get the current Move Element directory - Move the file to a new Place Copy element - Copy the file to a new place Renaming - item rename the existing New-item file - Create a new file for a full list of commands available to you, use Get-Command cmdlet. In the command line, you can enter the following: PS C: Get-Command It is important to note that Microsoft restricts users from using custom PowerShell mixtures in the default settings. In order to use PowerShell cmdlets, you need to change ExecutionPolicy from Limited to RemoteSigned. Remote signature will allow you to run your own scripts, but will stop unsigned scripts from other users. To change the execution policy, include the following PowerShell: PS C: 'Set-ExecutionPolicy To replay on RemoteSigned, hang out the following command: PS C: 'Set-ExecutionPolicy -ExecutionPolicy RemoteSigned Make sure you're in the administrator account so you have permission to set up a new execution policy. Script-based processes and commands are part of the core of PowerShell's versatility. In PowerShell, the script is, in fact, a text file with a PS1 extension in its file name. To create a new script, you can just open the Windows notebook, enter commands and save with '.ps1' at the end of the name. To run the script, enter its folder and file name into the PowerShell: PS c: 'powershell'mynewscript.ps1 Once you've done it, the selected script will be launched. Want to create your own PowerShell scripts? Nearly 5k students took this Udemy course on an extended script with PowerShell. Overlap with Windows Commands When You're New to PowerShell It feel overwhelming to try to learn a whole new library of commands. However, most new users don't realize that the syntax used on the Windows command line overlaps with PowerShell. It's This. facilitated by the fact that PowerShell is not sensitive to business. Much like Command Prompt, the PowerShell CD team still changes directories, and dir still provides a list of files in the selected folder. So it's important to remember that you're not necessarily starting from scratch. Taking this on board will help reduce the learning curve you encounter when using PowerShell and reduce the number of new commands that you need to learn. That being said, it's important to note that they're not considered full PowerShell commands as much as they are aliases (the name Powershell is for Windows team teams). So even if you can try some Command Prompt commands in PowerShell, you should learn as much as possible about new ones. However, the Command Prompt experience can definitely help new users cope with PowerShell and hit the ground running. Back up the S'L database Many people use PowerShell to back up S'L databases. The command line interface can hold complete backups of databases, backups of files, and backups of transaction logs. There are many ways to back up the database in PowerShell, but one of the easiest is to use a backup-SqlDatabase command. For example: PS C:'gt; Backup-SqlDatabase -ServerINstance Computer-Database Database, This will create a backup database database database called Databasecentral (or the name of the selected database. To back up the transaction log, you'd enter: PS C: No zgt; Backup-SqlDatabase -ServerInstance Computer-Instance -Database Centeral -BackupAction Log This will create a log of transactions of your selected database. Major PowerShell Teams List Using Aliases will only be you so far on Shell Power it is therefore important to commit to learning everything you can about the native PowerShell team. We touched on some of them above, but we're going to break down the main ones in much more detail below. Get-Help This team should be at the top of any new user's list when it comes to PowerShell. The Get-Help team can be used to literally assist with any other PowerShell team. For example, if you know the name of the team but don't know what it's doing or how to use it, the Get-Help team provides a complete team syntax. For example, if you want to see how Get-Process works, you're in a psY C: 'Get-Help -Get-Name-Process PS C: Set-ExecutionPolicy As it was affected earlier in this guide, Microsoft has a limited implementation policy that prevents you from writing powerShell scripts unless you change it. When you set up a execution policy, you have four options to choose from: Limited is the default execution policy that stops scripts from running. All signed - Will work scripts if they Trusted Publisher Remote Signature - Allows scripts to run that have been created locally unlimited - Policy without restrictions on the launch of PS C scripts: Get-ExecutionPolicy If you use PowerShell, you can't always work on a server server You're familiar with. If you see the server in question operating under a limited policy, you can implement the Set-ExecutionPolicy command to change it. Get-Service One of the most important commands is Get-Service, which provides the user with a list of all the services installed in the system, both working and stopped. This cmdlet can be sent using specific service names or objects. For example, if you're introducing PS C: Get-Service, you'll be shown a list of all the services on your computer, their statuses, and your display names. To use this command to get certain services, click: PS C: Get a WMI service to get all services that start with WMI. If you want to limit the output of active services on your computer, bring in the following command: PS C: Get-service (en) Where the object ($). Status-eq Run - ConvertTo-HTML If you use PowerShell, you may want to create a report on the information you've seen. One of the best ways to do this is with the ConvertTo-HTML command. This cmdlet allows you to create reports with tables and colors that can help visualize complex data. Simply select an object and add it to the team. For example, you can enter: Get-PSDrive ConvertTo-Html This returns a lot of information, so it's a good idea to limit its file to the Out-File team. The best alternative team is: Get-PSD Drive ConversionTo-Html Out-File -FilePath PSDrives.html This will generate an HTML file as a table. For example: You can add your own colors and boundaries to refine its view. Exports-CSV (and Get-Service) No less important to increase visibility is the Export-CSV team. This allows you to export PowerShell data to the CSV file. In fact, this team creates a CSV file that makes up all the objects selected in PowerShell. Each object has its own line or string in the CSV file. This team is mainly used to create spreadsheets and share data with external programs. To use this command, you would enter: PS C: Get-Service-CSV c:'service.csv It is important to remember not to format objects before launching the Export-CSV team. This is because the formatting of objects only results in the formatting of properties placed in the CSV file, not the original objects themselves. In case you want to send certain object properties to the CSV file, you'll use cmdlet Select-Object. To use cmdlet Select-Object, visit: PS C: Get-Service Object Choice Name, Export-CSV c status: 'Service.csv Get-Process If you want to review all the processes that currently work in your system, the Get-Process team is very important. To get a list of all the active processes on your computer, click: PS C: Please note that you don't specify the parameters, you get a breakdown of each active process on the on To select a specific process, narrow the results down by process name or process ID and combine them with the cmdlet Format-List, which displays all available properties. For example: PS C: Get-Process Window, Explorer Format-list - This provides comprehensive oversight of all active processes. Get-EventLog If you ever want to access your computer's event logs (or logs on remote computers) when using PowerShell, you'll need a Get-EventLog command. This cmdlet only works on classic event magazines, so you'll need a Get-WinEvent team for magazines later than Windows Vista. To work with the event log team in time: PS C: Get-EventLog-List It will show all the event logs on your computer. One of the most common reasons why users watch event logs is because they see bugs. If you want to see bug events in the magazine, just in the news: PS C: 'Get-EventLog -LogName System -EntryType Error If you want to get event logs from multiple computers, specify which devices you want to view (listed below as Server1 and Server2). For example: PS C: Get-EventLog - LogName Windows PowerShell -ComputerName local computer, Server1, Server2. Options that you can use to search event logs include: After - The user indicates the date and time and cmdlet will find events that occurred after AsBaseObject - Provides System.Diagnostics.EventLogEntry for each Event AsString - Returns exit in the form of lines Before - The user indicates the date and time, and cmdlet will find events that occurred before ComputerName - Used to indicate a remote computer EntryType - , Audit Bounce, Audit Success, Information, Warning) Index - Determines the values of the cmdlet index finds events from the list - Provides a list of event logs UserName - Identifies the names of users associated with this event Stop Process When using PowerShell, it is not uncommon to experience the freezing process up. Whenever this happens, you can use Get-Process to get the process name, having difficulty, and then stop it with the Stop-Process team. Typically, the process ends by name. For example: PS C: Stop-Process -Name NotePad In this example, the user stopped using the Stop-Process command. PowerShell: A powerful command line interface While switching to PowerShell may seem quite complicated, this command-and-line interface works just like any other. It may have its own unique cmdlets, but a wealth of internet resources can help you with any administrative task you may think of. To get the most out of PowerShell, you just need to get used to the many commands available to you. As a new user, it's easy to become stunned by PowerShell's with extra cmdlets. Make sure you start with the command line interface before the full-scale GUI ends. Whether you're new to PowerShell or team-line interfaces, more than enough information is available online to help you make the most of the most It's a powerful tool. Windows PowerShell commands are often asked questions The most important navigation actions you need to know for PowerShell, how to get into it and how to get out again. The easiest way to access the PowerShell environment is to enter PowerShell in the taskbar search box. PowerShell works in your own window so you can close it just by clicking on the X in the top right corner of the window frame. The right way to close the window is to enter the output and tip command. Command Prompt's standard navigation commands work in PowerShell, so use cd to change the catalog. Enter the disc letter followed by the colon (for example. D:) switch to another disk. PowerShell is a promotion on Command Prompt because its shell script capabilities include better programming designs than those available for batch assignments in Command Prompt. All Command Prompt commands are available in PowerShell, but then PowerShell has additional commands and utilities called cmdlets. Think of PowerShell as a command query. Bash script is a script of the Unix shell. Because Linux is an adaptation of Unix, the shell script written for Linux is often referred to as a bab script. There are many online lessons on how to create a Bash scenario. To avoid confusion, try not to refer to the PowerShell scenario as the Bash scenario. Script.
