# PERSONAL $HOME/.bashrc FILE for bash-2.05a (or later)
#
# Last modified: Tue Apr 15 20:32:34 CEST 2003
#
# This file is read (normally) by interactive shells only.
# Here is the place to define your aliases, functions and
# other interactive features like your prompt.
#
# This file was designed (originally) for Solaris but based
# on Redhat's default .bashrc file
# --> Modified for Linux.
# The majority of the code you'll find here is based on code found
# on Usenet (or internet).
# This bashrc file is a bit overcrowded - remember it is just
# just an example. Tailor it to your needs

# ALIASES AND FUNCTIONS
#
# Arguably, some functions defined here are quite big
# (ie 'lowercase') but my workstation has 512Meg of RAM, so ...
# If you want to make this file smaller, these functions can
# be converted into scripts.
#
# Many functions were taken (almost) straight from the bash-2.04
# examples.
