I am new to rails and have not found out how to do this. What I am
trying to do is execute a Linux command from one of my controllers.
For example, I’ve tried these 2 methods. Both result in a the web-page
to hang forever. I get NO response back.
The question I have is, how do I execute a Linux command and then
parse the output from this command to take further action. Much
io = IO.popen(“uname -a”)
output = io.read
