bashrc

# This file should be symlinked as ~/.bashrc. Its contents are executed whenever
# a new shell is launched (both login and non-login shells, by explicitly
# calling it from .profile). See also the documentation at the top of profile.
#
# This file should contain any definitions that live only for the current shell
# and are not inherited by subshells. These most particularly include alias
# and function definitions.
