Create a new script from a series of commands in your history… or copy them to the clipboard.

Use the current folder if you don’t have a WindowsPowershell\Scripts folder, and be more careful about overwriting existing scripts

  1. ## New-Script function
  2. ## Creates a new script from the most recent commands in history
  3. ##################################################################################################
  4. ## Example Usage:
  5. ##    New-Script ScriptName 4
  6. ##        creates a script from the most recent four commands
  7. ##    New-Script Clipboard -id 10,11,12,14
  8. ##        sends the the specified commands from the history to the clipboard
  9. ##    Notepad (New-Script ScriptName 20)
  10. ##        sends the most recent twenty commands to the script, and then opens the script in notepad
  11. ##################################################################################################
  12. ## As a tip, I use a prompt function something like this to get the ID into the prompt:
  13. ##
  14. ## function prompt {
  15. ##   return "`[{0}]: " -f ((get-history -count 1).Id + 1)
  16. ## }
  17. ##################################################################################################
  18. ## Revision History
  19. ## 1.0 - initial release
  20. ## 1.1 - fix bug with specifying multiple IDs
  21. ## 2.0 - use the current folder as the default instead of throwing an exception
  22. ##     - prompt to overwrite if not -Force
