dot_bashrc

# Amar Paul's .bashrc
# 	Login shells:							.bash_profile
#	nonlogin (i.e. open shell once in):		.bashrc
# On Mac (Terminal and iTerm2) all shells are login shells
# good explanation: http://www.joshstaiger.org/archives/2005/07/bash_profile_vs.html
#
# For Mac, file hierarchy is:
# .bash_profile > .bash_login > .profile 
#
# This .bashrc is sourced from .bash_profile (wanted to keep everything together)

# read .profile
[[ -r ~/.profile ]] && source ~/.profile

# shell aliases
[[ -r ~/.shell_aliases ]] && source ~/.shell_aliases

# and temporary aliases
[[ -r ~/.bash_aliases_tmp ]] && source ~/.bash_aliases_tmp
