Add showCommandForUser to process:System.Process http://hackage.haskell.org/trac/ghc/ticket/4305
There are many programs (e.g. ghc and Cabal) which run other programs, and when run with -v want to show the user what they are running. The user then often wants to run the command by hand, in order to debug a problem, but this can be tricky when the command or its arguments include spaces or other characters treated specially by shells.
*Which* shells, though, can it run in?
Ah, you are right, I should have added a haddock doc! -- | Given a program @p@ and arguments @args@, -- @showCommandForUser p args@ returns a string suitable for pasting -- into sh (on POSIX OSs) or cmd.exe (on Windows). Thanks Ian
