WARNING! Your ~/.bashrc file is based on an old copy of /etc/bash/bashrc, which
|
|
is not intended for use within a home directory. Please either delete ~/.bashrc
|
|
or replace it with a copy of /etc/skel/.bashrc before optionally customizing it
|
|
further. Neglecting to do so may result in bash behaving unexpectedly.
