This could happen if your command (“s”) outputs to stderr (instead 
of stdout).

You can either redirect the output to stdout or possibly handle both 
stdout and stderr from the command via something like popen3 or 
TextMate::Executor. With the latter, I think you can simply do:

     
#!/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby
     require "#{ENV['TM_SUPPORT_PATH']}/lib/tm/executor"

     s = #... command-line command that produces many lines of output
     TextMate::Executor.run(s)

Then the output should be wrapped in the HTML output theme, stderr will 
appear red, etc.
