Bug su command to non-root without password prompt
Thank you for your reply. I am not the root here. Someone is. The prdusr is shared by the production support team. I am one of the team members who wants to write a little alias to avoid entering the password every time I su prdusr.

The password also changes once a month for prdusr so to eliminate the password prompt completely might not go well with the production support team and defeats the purpose of the password protected prdusr.

Is there anyway I can ask Root to make use of sudo -S and treat su prdusr as if temporarily executed as if I was root ?

Root grants prdusr priviledge to kill any job but when prdusr executes sudo kill, it still prompts for password of prdusr. So what I was hoping is

cat passwd.txt | sudo -S su prdusr would allow me to switch to prdusr without a password prompt if root grants su prdusr 'command' priviledge to prdusr ?

It is very confusing because su prdusr might not be a command to unix kernel and su prdusr executed by root doesn't require a password prompt which only comes from the nature of sudo setup.

vipw

vipw(1B)					     SunOS/BSD Compatibility Package Commands						  vipw(1B)

NAME

       vipw - edit the password file

SYNOPSIS

       /usr/ucb/vipw

DESCRIPTION

       vipw edits the password file while setting the appropriate locks, and does any necessary processing after the password file is unlocked. If
       the password file is already being edited, then you will be told to try again later.  The vi(1) editor will be used unless the  environment
       variable VISUAL or EDITOR indicates an alternate editor.

       vipw performs a number of consistency checks on the password entry for root, and will not allow a password file with a "mangled" root entry
       to be installed.  It also checks the /etc/shells file to verify the login shell for root.

FILES

       /etc/ptmp

       /etc/shells
