Hey all,

I have a problem that I cannot wrap my head around. I have a  
capistrano task to kill my lighttpd process and restart it. Here is  
the subtask, stop\_lighttpd, that fails:  
task :stop\_lighttpd, :roles =\> :web do  
run “kill -9 `ps aux | grep lighttpd | grep #{deploy_to} | awk '{print $2}'` \> /dev/null”  
end

I know for a fact that when stop\_lighttp is ran. The process is  
indeed killed and kill should give a zero output signal. However,  
capistrano, doesn’t believe that it did. Here’s what it says:

pajaro:~/Projects/m\_hub/m\_hub luke$ cap restart\_web  
loading configuration /usr/local/lib/ruby/gems/1.8/gems/  
capistrano-1.1.0/lib/capistrano/recipes/standard.rb  
loading configuration ./config/deploy.rb

Any clues? Thanks in advance,
