Filtering and Transforming Text

  • There's no direct equivalent to awk in Windows, but you can use PowerShell or other scripting languages for similar tasks.

  • powershell -Command "(Get-Content file.txt) -replace 'World', 'Universe'": Use PowerShell to replace text.

  C:\> echo Hello World | powershell -Command "$input -replace 'World', 'Universe'"
  Hello Universe
