bashrc

# .bashrc
# bashrc is for aliases, functions, and shell configuration intended for use in
# interactive shells.  However, in some circumstances, bash sources bashrc even
# in non-interactive shells (e.g., when using scp), so it is standard practice
# to check for interactivity at the top of .bashrc and return immediately if
# the shell is not interactive.  The following line does that; don't remove it!
