Enable auto pressing on Tab at the Terminal

A trick that I met again and wanted to share because it never hurts.

Given that the users of GNU/Linux, it is impossible not to use the Terminal.

Also, do not forget:

The GUI makes it easy to complicated, but makes possible imposile Terminal!

Edit /etc/bash.bashrc

Wanted:

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

And delete the comment character (#) from the second line until the fourth.
Save the changes and it will be auto-activated by pressing the Tab key.
