Using Basic Commands
To begin working with PowerShell, you need to understand the concept of cmdlets and the basic command syntax. Cmdlets are specialized, lightweight commands used in the PowerShell environment. They follow a consistent verb-noun naming pattern, such as Get-Help or Get-Process. PowerShell commands are not case-sensitive, and parameters are typically preceded by a dash (-). You can use these cmdlets to perform tasks like retrieving help, listing available commands, or inspecting running processes on your system.

When you run a cmdlet such as Get-Process, PowerShell returns structured output in a table format. Each column represents a property of the item, such as process ID, memory usage, or process name. Understanding this output helps you quickly find relevant information. For instance, the ProcessName column shows the name of each running process, while the Id column gives the unique identifier for each process. You can use this information to monitor system activity or troubleshoot issues.
