If you are working with Debian Linux you have to the package manager “apt-get” to install packages. What is pretty cool. 1 mil. times better the the shitty RPM System from Red Had. If you want to have autocompletion for apt-get install the package “bash-completion”.
apt-get install bash-completion
and than add this lines to your “/root/.bashrc” file:
if [ -f /etc/bash_completion ]; then . /etc/bash_completion fi
