su - root script
Hi all,

I'm configuring a script to su from a normal user to root. What is the exact syntax to su to root + password provided inside the script?

For example: su - root will require password, I would want this password hardcoded inside the script

Thanks.

Hardcoding root passwords inside a script is a bad idea. For the script to be executable, it has to be readable by users, and any user that can read this script can see the root password. And that is not a great idea.

It probably would better to put a setuid c wrapper around this shell script so that you don't have to do su to root.

If you need to run the script on a regular basis, put it in "root cron"

Have you though about installing "sudo"
This will allow you to configure who can and can not run what scripts or commands as root with out the use of the root passwd and restrict the population of the root passwd to other users. Basicly you can get back control over the root account.
