Changing to root user inside shell script

Question

I have a shell script which needs non-root user account to run certain commands and then change the user to root to run the rest of the script. I am using SUSE11. I have use

Answer 1

The easiest way to do that would be to create a least two scripts.

The first one should call the second one with root privileges. So every command you execute in the second script would be executed as root.

For example:

runasroot.sh

sudo su-c'./scriptname.sh'

scriptname.sh

apt-get install mysql-server-5.5

or whatever you need.
