    I'm little confused about "process" in linux. How does linux assign privileges to processes that are created under different users? Say if a root user starts a process (say jboss server) does the jboss server will have root privileges? or will have a seperate privilege? can anybody suggest a site that have information about linux process.

    Thanks and Regards.

    The process is usually run by a specific user. if you log in yourself and run the program, it will run with the same privileges as yourself.

    So in your case if you run a root user starts jboss server, jboss server process will have root privileges.

    I think you can find a lot of information in this post:

    I am using linux mint and have installed Netbeans on it but whenever I run netbeans from accounts other than root it throws an error for not having permission to start glassfish server of netbeans. I also tried running this application using run as administrator option but then the application does not start.

    So is there a way to assign netbeans admin rights permanently so that whenever I start this application from other accounts I should not face this error?

    You probably need to use xdg-su:

    xdg-su provides a graphical dialog that prompts the user for a password to run command as user or as root if no user was specified.

    xdg-su is for use inside a desktop session only.

    If your launch command is /usr/bin/netbeans/, change it to xdg-su -c /usr/bin/netbeans.

    Alternatively, find out where netbeans stores its workspace and assign ownership to your current user.

    You could add the program you'd like to run as root into the sudoers file. (run the command "visudo" as root)
