Nobu, did you? -- Yusuke Endoh ---------------------------------------- Feature #1482: Kernel.exec doesn't respect COMSPEC environment variable on Windows https://bugs.ruby-lang.org/issues/1482#change-33705 Author: dolzenko (Evgeniy Dolzhenko) Status: Assigned Priority: Normal Assignee: nobu (Nobuyoshi Nakada) Category: core Target version: 2.0.0 =begin Here is pretty convoluted test case: puts ENV["COMSPEC"] # => "C:\WINDOWS\system32\mycmd.exe" File.open("1.bat", "w") { |f| f.write("time") } # create test batch file with command which waits for user input Kernel.exec("1.bat") # now the process tree inspection shows that the "C:\WINDOWS\system32\cmd.exe" is still used to interpret 1.bat =end -- http://bugs.ruby-lang.org/
