C programms with RoR

I had develop in an other project some C programms and now I'm
developing a website in RoR. I want to have a page where I can upload
files and with those files, execute my C programms (I made a bash script
to execute these programs).

Did someone know how I can do that ??

result = `my_script.sh`

Note the back-ticks ``. They create a pipe.
