Using su in a shell script

Hello, UNIX-Forums.

How can I use su in a shell script?

Code:
echo "Please enter the root password below."
su
echo "Thank you."

Desired output:
Code:
me@pc:~$ bash file
Please enter the root password below.
Password:
Thank you.

But the script exits after su:
Code:
me@pc:~$ bash file
Please enter the root password below."
Password:
root@pc:~#

How can I become root in a shell script without the use of sudo?

Thanks in advance,
intelinside

are you sure that the u are not root user ?
because su forks the new subshell and when you back(exit) to subshell then you can go on the script..
# 3  
Yes, I'm sure.
