How to Use two different users in bash scripting

Question

Hi everyone, I am writing a bash script on RedHat V5.1. In this script i have to run one command using dbAdmin and right after that i have to switch again to root user to run the other commands. Can anybody tell me how i can do this in bash scripting.

Thanks in advance....

Answer 1

You need to run your script as root.Then in any part of code just do this:

su - dbadmin -c "command"

Replace command with whatever you want to run under dbadmin user.

This is exact way how redhat init scripts run services under specific users, eg. oracle DB

Answer 2

Try using the SUDO command to switch between root and your dbAdmin account.
