Subject: [ruby-talk:27991] system() broken in RubyCentral ruby?


I wrote and tested a ruby app in the full cygwin environment with ruby 1-6-5
in win2k.  In an attempt to distribute this app, I installed
http://dev.rubycentral.com/downloads/files/ruby165-0.exe on a different
virgin win2k pc.  My app had troubles with a system call not running (and
returned false).

When I printed out the string in the system call and pasted it into the
Start/run dialog, it worked fine on both PCs.  After spending some time, I
narrowed the problem case down to any string with a " or a \.

This code works fine on my development full cygwin environment, but on the
rebyCentral install, the last two cases fail (return false):

system('cmd.exe /c dir c:')     ==> works on both environments

system('cmd.exe /c dir c:\\')   ==> fails only in RubyCentral env

system('cmd.exe /c dir "c:"')   ==> fails only in RubyCentral env


Can someone tell me what is going on?
