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

Fixes a bug in the first one which made you unable to specify multiple IDs as intended.

  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 ScriptName -id 10,11,12,14
  8. ##        creates a script from the specified commands in history
  9. ##    New-Script Clipboard 2
  10. ##        sends the most recent two commands to the clipboard
  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. ##################################################################################################
