One of the most helpful feature I find in linux boxes is it autocomplete fasility. This feature will make our job more easier. But in some servers or VPS this option is desabled by default or relevent packages for autocomplete where not installed. To enable autocomplete we need to two things.

1. Install the package “bash-completion”

$ sudo apt-get install bash-completion

2. Add the following lines to the file ~/.bashrc or /etc/bash.bashrc

if [ -f /etc/bash_completion ]; then
    . /etc/bash_completion
fi
