What does the bash.rc look like in a fresh install of LInux Mint.

Hello, Loonix3.

A file named bash.rc on a freshly installed Linux Mint defaults to being absent.
When starting the bash shell will look for these files:
  • /etc/bash.bashrc, the system wide initialization file
  • the personal initialization file ~/.bashrc

The default content of /etc/bash.bashrc very likely depends on the exact version of the bash shell. This is what it looks like on Linux Mint 13 x64 Cinnamon desktop:
Code: Select all
# System-wide .bashrc file for interactive bash(1) shells.

# To enable the settings / commands in this file for login shells as well,
# this file has to be sourced in /etc/profile.

# If not running interactively, don't do anything
[ -z "$PS1" ] && return

# check the window size after each command and, if necessary,
# update the values of LINES and COLUMNS.
shopt -s checkwinsize

# set variable identifying the chroot you work in (used in the prompt below)
if [ -z "$debian_chroot" ] && [ -r /etc/debian_chroot ]; then
    debian_chroot=$(cat /etc/debian_chroot)


# Set colorful PS1 only on colorful terminals.
# dircolors --print-database uses its own built-in database
# instead of using /etc/DIR_COLORS.  Try to use the external file
# first to take advantage of user additions.  Use internal bash
# globbing instead of external grep binary.
safe_term=${TERM//[^[:alnum:]]/?}   # sanitize TERM
[[ -f ~/.dir_colors   ]] && match_lhs="${match_lhs}$(<~/.dir_colors)"
[[ -f /etc/DIR_COLORS ]] && match_lhs="${match_lhs}$(</etc/DIR_COLORS)"
[[ -z ${match_lhs}    ]] \
        && type -P dircolors >/dev/null \
        && match_lhs=$(dircolors --print-database)
[[ $'\n'${match_lhs} == *$'\n'"TERM "${safe_term}* ]] && use_color=true

if ${use_color} ; then
        # Enable colors for ls, etc.  Prefer ~/.dir_colors #64489
        if type -P dircolors >/dev/null ; then
                if [[ -f ~/.dir_colors ]] ; then
                        eval $(dircolors -b ~/.dir_colors)
                elif [[ -f /etc/DIR_COLORS ]] ; then
                        eval $(dircolors -b /etc/DIR_COLORS)

        if [[ ${EUID} == 0 ]] ; then
                PS1='${debian_chroot:+($debian_chroot)}\[\033[01;31m\]\h\[\033[01;34m\] \W \$\[\033[00m\] '
                PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[01;34m\] \w \$\[\033[00m\] '

        alias ls='ls --color=auto'
        alias grep='grep --colour=auto'
        if [[ ${EUID} == 0 ]] ; then
                # show root@ when we don't have colors
                PS1='\u@\h \W \$ '
                PS1='\u@\h \w \$ '

# Try to keep environment pollution down, EPA loves us.
unset use_color safe_term match_lhs

# Commented out, don't overwrite xterm -T "title" -n "icontitle" by default.
# If this is an xterm set the title to user@host:dir
#case "$TERM" in
#    PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME}: ${PWD}\007"'
#    ;;
#    ;;

# enable bash completion in interactive shells
if [ -f /etc/bash_completion ]; then
    . /etc/bash_completion

# if the command-not-found package is installed, use it
if [ -x /usr/lib/command-not-found ]; then
   function command_not_found_handle {
           # check because c-n-f could've been removed in the meantime
                if [ -x /usr/lib/command-not-found ]; then
         /usr/bin/python /usr/lib/command-not-found -- $1
                   return $?
         return 127


The default content of the personal ~/.bashrc file will depend on the template to be found under /etc/skel. At least on Linux Mint 13 x64 Cinnamon desktop, /etc/skel does not offer a default .bashrc file.

Kind regards,
Endless legions of bigoted, brutal, bloodthirsty Orcs from the dark land of Mordor are bringing desolation, despair and death to the poor inhabitants of the Middle East. [1]
