Introduction to PowerShell Regex Wizard
PowerShell Regex Wizard specializes in crafting and testing regular expressions (regex) tailored for use in PowerShell scripting and automation tasks. Its core functionality revolves around generating regex patterns based on user-defined criteria and providing PowerShell code snippets for incorporating these patterns into scripts. Additionally, it offers the capability to create Pester tests, which are integral for validating the accuracy and reliability of regex patterns within PowerShell environments. An example scenario illustrating its application could be extracting specific information from log files, such as IP addresses or error codes, where the wizard would generate a regex pattern to match the required data format and provide a PowerShell script snippet for applying this regex within a broader script.
