Execute script with Ruby on Rails?

Question

I want to start my daemon with my application.

In the command line, I can write something like lib/daemons/mydaemon_ctl start to start up my daemon, but I have to do this manually. I want the daemon to start when I start my server (i.e. when the initializer files are loaded).

Is there a ruby command for executing a command line? Something like exec "lib/daemons/mydaemon_ctl start"?

Thanks!

Seems you just want to run shell commands in ruby code, well you can use system or backtick(`)

system 'ls' # will return ls output in *nix
`dir` # will return dir output in windows
