How do I get a windows .bat file to return a proper exit code? RubyGems build stubs that look something like this: “c:\ruby\bin\ruby” -x “%~f0” %\* goto endofruby #!/bin/ruby abort ‘boom’ **END** :endofruby But if I run this: ruby -e “system ‘stub.bat’; p $?” I get the wrong exit code (0 instead of 1). If I can get the right exit code then failure to build rake extensions will fail installs properly in Rubygems. – Eric H. - removed\_email\_address@domain.invalid - [http://blog.segment7.net](http://blog.segment7.net) I LIT YOUR GEM ON FIRE! ---

What do you get when you put: exit %ERRORLEVEL% under the :endofruby label? From my quick test, the ruby interpreter returns a proper code, and the command shell sets the ERRORLEVEL variable correctly. ---

Hrm, it seems that gems doesn’t generate .bat files, but instead generates .cmd files. I’ll ask Curt about this. – Eric H. - removed\_email\_address@domain.invalid - [http://blog.segment7.net](http://blog.segment7.net) I LIT YOUR GEM ON FIRE! ---

I’ll ask Curt about this. Should work the same in either. Since going with .cmd files discards Windows 98 compatibility (rightly), there are some other tricks that can be safely invoked. As a .CMD, ‘EXIT’ can take a /B argument that will exit from the script, but not the command shell as a whole.
