UNIX for Dummies Questions & Answers

Hi there,
I got to find out that if I make changes in the prompt or command aliases from .bashrc, I could apply those changes immediately with the command:

Code:

source ~/.bashrc

There's another situation when I'd like to apply changes without loging out and in again: If I add someone to a group of user so he/she can access some files, how can this person apply changes immediatly?

Thanks for your help.

Unfortunately a login is the only way to obtain user and group permissions.

Thanks Corona for your answer.
At least I know that I can stop searching for more.
