'~/.bashrc' vs ' /etc/skel/.bashrc'. Why are there two '.bashrcs'?

Solution 1:

Every file in /etc/skel gets copied to a (new) users $HOME directory when your create a new user. If they are the same you either have not made any changes to your file (most likely) or you copied your custom file to /etc/skel.

See:

Solution 2:

/etc/skel/.bashrc is a default .bashrc for every user created in the system.

~/.bashrc is individual for each user.
