The Command su can be used by two categories of users, the Root, that is, su and all other users.

    when su wants to login as root from any other user session, then he/she can do so by giving the su with no option and by supplying the root password. By this way the root can take the form of that user and the privileges will be same as that of that user to which login was made by su.
   Ex:
[training1@linuxcvs training1]$ pwd
/home/training1
[training1@linuxcvs training1]$ su
Password:
[root@linuxcvs training1]# pwd
/home/training1    

   on the other hand, when su is in his/her own id and when su wants to login as some other user while being in super user account then su can do so just by giving the su + account user's name. This situation will not prompt for password.
      Ex:
[root@linuxcvs /root]# pwd
/root
[root@linuxcvs /root]# su training1
[training1@linuxcvs /root]$ pwd
/root  

    But when the other users want to login as su, then there have to give the su + other user account's name to which they want to login and in addition should give the password of that user to which the user wants to login.
Ex:
[training1@linuxcvs training1]$ su training1
Password:
[training1@linuxcvs training1]$

   This cannot be put directly in a script as this gives the error:
standard in must be a tty
   meaning the input can should be supplied from the terminal only.

With Regards,
Vivek
