Forming sanitary shell commands or system calls in Ruby

Question

I\'m building a daemon that will help me manage my server(s). Webmin works fine, as does just opening a shell to the server, but I\'d prefer to be able to control server ope

This is an old question, but since it's pretty much the only real answer you'll find when googling I thought I'd add a caveat. The multi argument version of system seems reasonably safe on Linux, but it is NOT on Windows.

Try system "dir", "&", "echo", "hi!" on a Windows system. Both dir and echo will be run. Echo could of course just as well be something far less innocuous.
