PowerShell commands every developer should know

php editor Apple introduces you some PowerShell commands that every developer should know. PowerShell is a task automation and configuration management framework for Windows operating systems. By mastering these commands, developers can manage and operate the system more efficiently and improve work efficiency. These commands cover common file operations, process management, network settings and other functions, and are very practical. Whether you are a beginner or an experienced developer, mastering these commands can help you better cope with various scenarios in your development work. Let’s learn about some important PowerShell commands together!

However, mastering the power and flexibility of PowerShell requires a steep learning curve. For those who are new to using PowerShell, it is recommended to learn the following basic commands in order to become proficient in this scripting language over the long term.

1. Get Help

Get-Help is part of the PowerShell integrated help system. It can help you find necessary information about commands, concepts and functions, and can also identify aliases and scripts, etc.

To get help for a PowerShell cmdlet, you need to use the Get-help cmdlet, followed by the cmdlet name. For example, to view the summary and syntax associated with the get-process cmdlet, type:

Get-Help Get-Process
This command reads annotation-based and XML-based help provided by the function author.

Alternatively, you can use the Get-Help -online command to get help for PowerShell cmdlets online. For example, to view Microsoft's Get-Content cmdlet online documentation, type:

Get-Help Get-Content -online

2. Get Process

Get-Process Command Helps you retrieve and display a list of all active system processes and their identifiers (IDs). You can use it as an effective alternative to Windows Task Manager to view, stop and restart system processes.

For example, if you need to stop the GameBar process, you first need to find the process ID associated with it. So, enter:

Get-Process
This command will display all running system processes. Next, find the ID associated with the process you want to stop. To stop the process, type:

Get-Process -ID 20496 | Stop-Process
where -ID 20496 is the ID of the process (GameBar) you want to stop.

3. Start a process

You can use the Start-Process cmdlet in PowerShell to start one or more processes on the local computer. To use the cmdlet, type Start-Process followed by the process name. For example, if you want to start a new Notepad process, type:

Start-Process notepad
Additionally, you can use arguments to Start-Process to specify options. For example, if you need to start a process as an administrator, type:

Start-Process -FilePath “notepad” -Verb runAs

4. Get Command

Get - Command allows you to view all PowerShell commands installed on your computer. Similar to Get-Help, you can use Get-Command followed by a search query to find commands for a specific function.

Because Get-Command displays all commands, you can specify parameters to find functions with a specific name and CommandType. For example, to find cmdlets (CommandType) that begin with A (name), type:

Get-Command -Name A* -CommandType cmdlet
Alternatively, type Get-Help Get-Command -Examples to See more examples.

5. Get Service

Get -Service cmdlet allows you to view the status of the computer and the list of services. By default, the Get-Service command returns all services (stopped and running).

You can use parameters to specify and find services based on their status, name, and related services. For example, to see all services that start with the name Win, type:

Get-Service -Name “Win*”

6. Get ChildItem

You can use PowerShell Search the directory. The Get -ChildItem command is a convenient cmdlet for finding folders and files and quickly performing content-based searches without using File Explorer.

To view all top-level folders in the C:\\ directory, type:

Get-ChildItem "C:\\"
Also, use the -Path parameter to view specific files folders, subfolders and contents. For example, to view all subfolders and files in the Programs Files folder, type:

Get-ChildItem -Path "C:\\Program Files"
Additionally, use the -Recurse parameter to view Specify all files in the folder. Use the -Name parameter to view the project names in the directory.

Get-ChildItem -Path “C:\Program Files\Fodler_Name” -Recurse | Select FullName
In the above command, replace sub-folder with the folder name to view its contents.

7. Copy Item

The Copy -Item cmdlet allows you to copy and paste files and folders and their contents into different directories. To copy files and folders, type Copy-Item, followed by the source-Path, -Destination parameters, and the destination address. For example, to copy E:\\Folder1 and its contents to E:\\Folder2, type:

Copy-Item “E:\\Folder1” -Destination “E:\\Folder2” -Recurse
Please note that the -Recurse parameter in the above command is responsible for moving all folder contents. Without it, PowerShell will only copy the top-level folder (Folder1) and the files specified in the command.
