Hello,
Just read a foregoing mail and curious I installed
as told:
  Gofer new
	squeaksource: 'MetacelloRepository';

	package: 'ConfigurationOfOSProcess';
	load.

  (Smalltalk at: #ConfigurationOfOSProcess) project bleedingEdge load.

To load CommandShell, you can start with:

  Gofer new
	squeaksource: 'CommandShell';

	package: 'CommandShell-Piping';
	load.
Running the SUnittest on it: see picture included ..
What to do (a newbie) PC: Vista, Pharo .14 ..
