If you're a TAB fond, you may have liked the bash_completion feature in bash 2.0. Here is how to get it working with fedora 3.
1. Download the bash_completion rpm from Here
2. Install it : (as root) rpm -ivh bash-completion-20041017-1.1.fc3.rf.noarch.rpm
3. Edit /etc/bashrc (need to be root too) and add at the end this :
if [ -f /etc/bash_completion ]; then
4. Enjoy !
