Status changed from Open to Rejected Backport changed from 2.1: REQUIRED, 2.2: REQUIRED, 2.3: REQUIRED to 2.1: DONTNEED, 2.2: DONTNEED, 2.3: DONTNEED It's wrong code. The second argument must be '/C'. ```ruby exec(['cmd.exe', '/C'], '/C', 'echo', 'argv_zero') ``` ---------------------------------------- Bug #12234: Kernel#exec with a command array broken on Windows as of Ruby 2.2.4 https://bugs.ruby-lang.org/issues/12234#change-57870 * Author: Vais Salikhov * Status: Rejected * Priority: Normal * Assignee: * ruby -v: ruby 2.2.4p230 (2015-12-16 revision 53155) [i386-mingw32] * Backport: 2.1: DONTNEED, 2.2: DONTNEED, 2.3: DONTNEED ---------------------------------------- On Ruby 2.0.0 this worked as expected: ``` C:\Users\Administrator\GitHub\spec>ruby -ve "exec(['cmd.exe', '/C'], 'echo', 'argv_zero')" ruby 2.0.0p247 (2013-06-27) [i386-mingw32] argv_zero ``` On Ruby 2.2.4 it is broken - it seems to be getting stuck somehow in the new shell and never returns: ``` C:\Users\Administrator>c:\Ruby\ruby-2.2.4-i386-mingw32\bin\ruby.exe -ve "exec(['cmd.exe', '/C'], 'echo', 'argv_zero')" ruby 2.2.4p230 (2015-12-16 revision 53155) [i386-mingw32] Microsoft Windows [Version 6.1.7601] Copyright (c) 2009 Microsoft Corporation.
