su

Hello community,

Is there a way to perform su - userb without asking for password.

I tried
1 -in visudo userb ALL=(ALL) NOPASSWD(ALL)
This outcome allows me to run sudo without asking for password but still ask for su -
2- added the same user at the bottom (same outcome)
3- change the user to wheel but still ask for su -
And change the original user group

Anyone have a solution for this ?
Thanks

you could do an alias in .bashrc leaving your sudoers file with no passwd for wheel, or sudo group.

Code:

alias su='sudo su -'

$ su

Can I ask why you'd want to do that ?

see man su, su cannot be used without password.
using su and sudo together is deprecated.
I think what you really need is sudo, not su.
And as it was asked in post #5 why do you need it at all?

laziness No. 1 leading cause for all short cutting, or time management 2nd leading cause.
