It can easily leave you wide open to a hack.Assuming you do really mean a ruby script, and nothing in your Rails app, you can set the setuid bit with chmod and chown the script to root. When it executes, it will execute with root persmissions.Given you've not been able to find this information yourself, I'd again caution you not to do this.--
That is insecure, yes.
It is possible to use sudo in situations like this, where you don't really have user access to type in the password securely.
Sudo can be configured to allow a user to execute a command or a class of commands with elevated privileges.
Read the sudoers man page for more information on how to set this up.
Nevertheless, I caution you to avoid this situation. I am unclear *why* you need to do this from inside an application.
