Change the privileges needed to run a program
Hi everyone, I have an issue with a project of mine. I have to run a program on a terminal which requires to be logged in as su to have it run it. Given that I'm having problem to use expect to give the password I'd like to change the privilege of that program from SU to normal user ( I have the SU password, the problem is that it's going to be a standalone machine with everything automated).
Sorry for my English, I'm not a native speaker
Thanks for your help
