bashrc

This has been shamelessly copied from Gentoo and modified when needed

# This file is sourced by all *interactive* bash shells on startup,
# including some apparently interactive shells such as scp and rcp
# that can't tolerate any output.  So make sure this doesn't display
# anything or bad things will happen !

# past this point for scp and rcp, and it's important to refrain from
# outputting anything in those cases.

bash_profile

See User:Erus_Iluvatar/conky : this file is only used when the shell is a login one (on my setups, this mostly happens through ssh).
I like to have a quick system overview in this case.

/home/erus/.bash_profile
