This document discusses various techniques for working with strings and text files in PowerShell including: 1. Creating strings using single or double quotes, and using backticks to span strings across multiple lines. 2. Reading and writing content from text files using Get-Content and Set-Content, including joining lines with newlines and extracting numbers using regular expressions. 3. Finding strings within multiple text files using Select-String and filtering results.
