Can Automator .workflow Services Be Installed via Terminal Without User Consent?

In 10.6, you should be able to disable them by unchecking them in the Keyboard->Keyboard Shortcuts->Services list in System Preferences. For previous versions of OS X, there's a handy little app called Service Scrubber.

Hunting down and deleting services for apps you've already deleted can be troublesome; there are some detailed hints and tips in this article. Summary: find all the Info.plist files on your system that contain "NSServices", using a terminal command like:

find / -name "Info.plist" -exec grep -l "NSServices" {} \;

and (carefully) edit the suspect Info.plist files by hand.

Figured out how to do it myself based upon adapting the following article.

Added a line in to run the python command:

on run {input, parameters}
  tell application "Terminal"
    activate
    if (the (count of the window) = 0) or ¬
     (the busy of window 1  = true) then
      tell application "System Events"
        keystroke "n" using command down
      end tell
    end if
    do script "cd \"" & (POSIX path of ¬
     (input as string)) & "\"" in window 1
    do script "python -m SimpleHTTPServer 8000" in window 1
  end tell
  return input
end run
