I accidentally overwrote the /etc/bash.bashrc file.

Please give me the default content in that file to restore, or the file itself.


If you overwrote your bash the best way is to copy it again from your system itself instead of someone else:

rm ~/.bashrc
cp /etc/skel/.bashrc ~/

    OP is asking about /etc/bash.bashrc, not ~/.bashrc – wjandrea Jul 26 '16 at 2:59

My /etc/bash.bashrc file is the following:

# 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 a fancy prompt (non-color, overwrite the one in /etc/profile)
PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '

# 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 ] && ! shopt -oq posix; then
#    . /etc/bash_completion

# sudo hint
if [ ! -e "$HOME/.sudo_as_admin_successful" ]; then
    case " $(groups) " in *\ admin\ *)
    if [ -x /usr/bin/sudo ]; then
    cat <<-EOF
    To run a command as administrator (user "root"), use "sudo <command>".
    See "man sudo_root" for details.


# if the command-not-found package is installed, use it
if [ -x /usr/lib/command-not-found -o -x /usr/share/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 $?
                elif [ -x /usr/share/command-not-found ]; then
           /usr/bin/python /usr/share/command-not-found -- $1
                   return $?
           return 127

However, you could also just boot from a live CD and copy the live CD file onto your hard-disc i.e.

sudo mkdir /mnt/tempmount
sudo mount -t ext4 /dev/sda1 /mnt/tempmount
sudo cp /etc/bash.bashrc /mnt/tempmount/etc/bash.bashrc

Change /dev/sda1 for whatever partition your ubuntu is installed on.

    Or you can download the bash package, extract it via Nautilus, and find the file there. packages.ubuntu.com/maverick/i386/bash/download – arrange Aug 2 '11 at 21:15

    that's looks like a good answer - why not add one? – fossfreedom Aug 2 '11 at 21:21
  • well, it's much much easier to copy the source you posted here I guess... ;) It's just an alternative approach for reference. – arrange Aug 2 '11 at 21:25

Get it from the Bash package

  1. Download the Bash package:

    apt-get download bash

    Or manually download it from https://packages.ubuntu.com/bionic/amd64/bash/download

    • For other Ubuntu versions, swap out "bionic" for your version name.
  2. Browse the .deb file using Archive Manager
  3. Extract /etc/bash.bashrc
    • You can also find ~/.bashrc under /etc/skel/.bashrc.

Copying the root .bashrc into my folder was the easiest solution for me.

 sudo cp /root/.bashrc ~

    This, however, requires root privileges. – Rafał Cieślak Jan 12 '14 at 19:54

In addition to the the information given by Braiam, you can copy the contents of the following .bashrc file as commented in How to restore .bashrc file?
