Windows PowerShell Select-String Sample
This sample creates a cmdlet called Select-Str that searches files for specified patterns. The patterns can be case-sensitive or case-insensitive. The user can also specify a script block to use for performing the matching operation instead of relying on the cmdlet's own logic which uses regular expressions for matching.
Sample Objectives
This sample demonstrates the following:
- Using PSPaths with cmdlet parameters.
- Using script blocks with cmdlet parameters.
- Using session state in a cmdlet implementation.
