Is there a reference to all Windows "errorlevel" by command? Looking for a page that defines all error levels, by command.
here http://wiki.fdos.org/Main/ExitCodes is an old list that covers many typical command line commands
here http://www.computerhope.com/doserror.htm is a list of the most typical error messages with an explanation
and here http://en.kioskea.net/faq/sujet-2347-error-codes-in-windows is a more complete list of windows error codes, some are surfaced as exit codes and some are not.
