bashrc

#!/bin/bash -eu
#
# A simple bashrc
#
# Recommended use is to append this block to your ~/.bashrc file so you can
# keep this directory under version control:
#
# if [ -f $HOME/dotfiles/bashrc ]; then
#     . $HOME/dotfiles/bashrc
# fi
#
# Deliberately simple in order to enable easier hacking
#
# Some of the functions, eg _exit, are intended as an example of a feature of bash
# rather than being inherently useful by themselves.
#
# Contributions welcome


# Use the dotfiles prompt if it exists
if [ -f $HOME/dotfiles/promptrc ]; then
    . $HOME/dotfiles/promptrc
fi

# Use the dotfiles vimrc if one doesn't exist already
if [ ! -f $HOME/.vimrc ]; then
    ln -s $HOME/dotfiles/vimrc $HOME/.vimrc
fi
