A .ps1 file is a text file containing commands written in the PowerShell scripting language. PowerShell is a task automation and configuration management framework from Microsoft, consisting of a command-line shell and the associated scripting language. These scripts are used to automate administrative tasks, manage system configurations, and perform various other operations on Windows systems and increasingly on other platforms like Linux and macOS. PowerShell scripts can range from simple one-liners to complex programs with functions, loops, and conditional statements. They can interact with the operating system, access files and directories, manage processes, and communicate with other applications. The scripts are executed by the PowerShell interpreter, which interprets the commands and performs the specified actions. Security is a key consideration when working with PowerShell scripts, as they can potentially perform powerful and potentially harmful operations. PowerShell includes security features such as execution policies to control which scripts can be run and digital signatures to verify the authenticity of scripts.
