Linux command for switching user with password as parameter

I want to write the Linux shell script that switches the user without asking for password, i.e. password can be specified as the parameter.

I have my script like this startService.sh

sudo su hduser -p mypassword

but this is not working.

Can anyone tell how to specify the password in the command itself?

You could use the -S switch which reads the password from standard input like this:

echo 'password' | sudo -S command

From the man page:

-S (stdin) option causes sudo to read the password from the standard input instead of the terminal device. The password must be followed by a newline character.

But there's a catch. It works for the current user only. I can't find a way around it, at least.
