Dear friends ,

I want to "su - root" or "su - 'to another user'" without password .

Because i need to execute the following script :

/bin/su bschorun - c "/opt/bea/tuxedo9.1/bin/tmboot -y


But in this case it wants user password . But i need to execute it without password .


Plz help me, how can I do it ?

root#
root#sudo su anotheruser
anothheruser#

or as some other user
anotheruser#sudo /bin/su bschorun - c "/opt/bea/tuxedo9.1/bin/tmboot -y

Using su to become root without a password is the same as allowing root to log in without a password. It creates a big security risk.

But, for a script, I'm not sure why this is necessary. You can just run the script as root, or you can have the system run it as part of boot up or under cron.

As I read the command (not a script), you want to su to the user "bschorun", and then run the command "tmboot -y". You can su to become any user if you are root--or have root priveleges. But you can't su to another user from your login--unless you have the user's permission.

Perhaps you can describe more about what you are trying to do.
