¿Cómo activar que confirme antes de eliminar o sobreescribir ficheros en modo consola?

Ejemplo Fichero: /etc/bash.bashrc

# System-wide .bashrc file for interactive bash(1) shells.

# If not running interactively, don't do anything
[ -z "$PS1" ] && return

# check the window size after each command and, if necessary,
# update the values of LINES and COLUMNS.
shopt -s checkwinsize

# set variable identifying the chroot you work in
if [ -z "$debian_chroot" -a -r /etc/debian_chroot ]; then
    debian_chroot=$(cat /etc/debian_chroot)
fi

# set a fancy prompt (overwrite the one in /etc/profile)
PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w \$ '

# If this is an xterm set the title to user@host:dir
case "$TERM" in
xterm*|rxvt*)
    PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME}: ${PWD}\007"'
    ;;
*)
    ;;
esac

# enable bash completion in interactive shells
#if [ -f /etc/bash_completion ]; then
#    . /etc/bash_completion
#fi
