Why terminal shows “/home/igoru /etc/bash_completion” every time I open it?

Question

I've added some lines to ~/.bash_aliases yesterday... And today my gnome-terminal started showing me this expression in the beginning, just before the prompt.

/home/igoru /etc/bash_completion
igoru@igoru-ubuntu:

Those are the lines I added:

alias realias='vim ~/.bash_aliases; source ~/.bash_aliases'
alias ..='cd ..'
alias .='echo $PWD'
alias canhaz='sudo apt-get install'

What is happening?
Is this expression really related to those aliases, or what?

Answer 1

"." is a synonym for "source." Some line in some file is trying to source /etc/bash_completion after you have aliased it to "echo $PWD."

I think realiasing the bash builtins is a bad idea. Too many scripts will depend on it to act the original way. Consider "." a reserved keyword.
