Batch command file quits mysteriously

From: RichardOnRails on 8 Jul 2010 20:35 Hi, I decided to create a batch file to build a RubyOnRails application step-by-step. I want to take this approach so that I'd have a reproducible build process. After a couple of commands to switch to the required working directory, the first substantive Rails command was invoked. It's a command that's always worked reliably for me and I believe many Rails programmers. Judging by its output, I believe it worked correctly from this batch-file invocation. But the immediately following command was not executed. I'd like to find out why. Below is version stripped of most of the things relevant to this problem: The Command Window output is provided also.

Some executables return control to the invoking batch file immediately after being invoked. Others only do it after they themselves finish. It depends on how they are written. Rails.exe appears to belong to the second class. You can get around the issue like so: start /b rails RTS2 �d mysql A more robust approach would look like this (because it specifies the full path to rails.exe): start /b "Ruby on Rails" /d "c:\Program Files\Rails" rails.exe RTS2 �d mysql |
