Updating .bashrc file
 

I am playing around with aliases in the .bashrc file. After ^O and ^X, I have to logout and log back in each time to test the alias. Is there any way to update/refresh the user's .bashrc without logging out?

Thanks.

yes, you open a second shell to play and take care about your original shell and original .bashrc inside (without doing anything, just in case you need to restore the original .bashrc).

battles...

You just need to re-read the .bashrc file to refresh your aliases..

Yes, in general, but no in some special cases - when you made a critical error inside. You would better open another shell to check if that works and leave the original intact.

Thanks. Just doing a
. .bashrc
refreshed it.
