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.
