# /etc/bashrc
#
#####################################################################
# Basic bash startup files explanation:
#
# /etc/profile ==> System-wide initialization file containing global/system
#		environment variables and startup programs
# /etc/bashrc ==> System-wide aliases and functions, and some modifications to
#		/etc/profile (to help maintain /etc/profile as original as possible)
# ~/.bash_profile ==> Local/Personal environment variables and startup programs
#		called only during login
# ~/.bashrc ==> Anything local/personal and peculiar to the user
#
# login command programmatically sources /etc/profile and then ONLY
#		~/.bash_profile, OR ~/.bash_login, OR ~/.profile in that search order
#
# logout command programmatically sources ~/.bash_logout
#
# non-login consoles such as xterm/konsole programmatically sources ~/.bashrc
#
# /etc/bashrc is not sourced programmatically and must be sourced manually
#
# local setup:	~/.bash_profile sources ~./bashrc and executes /usr/local/bin/bash_login
#				~/.bashrc sources /etc/bashrc
#				~/.bash_logout executes /usr/local/bin/bash_logout
#####################################################################
#
# default bash prompt environment variables ($PS1-$PS4) for non-X consoles are
#		first defined system-wide in /etc/profile, but redefined (beautified) in /etc/bashrc
# bash prompt for xterm/konsole is modified in /etc/bashrc (below), but may be modifed by
#		users in ~/.bashrc
# make any personal changes to the X or non-X console prompts in ~/.bashrc

# Modify the system-wide shell prompts. The bare-bones prompt is defined initially
# in /etc/profile. As this file is sourced by ~/.bashrc, the prompt is redefined and
# beautified here. The modified system-wide non-X prompt includes the terminal (tty)
# number. The modified system-wide X (console) prompt excludes that information.

# First determine our location. This box uses three different Slackware
# installations. Modifying the prompt helps the user identify which installation
# is being used. Nothing fancy here, just creating an additional variable to
# modify the prompt.
# Using partition numbers but host names also could be used.
# Normal primary boot=/dev/hda10
# Alternate boot=/dev/hda13
# Testing boot=/dev/hda16
