I put source /etc/profile in /etc/bash.bashrc and unable to open terminal window in ubuntu 16.04, and now, whenever I try to open a terminal window, it closes after a few seconds. During those few seconds, there is no prompt and it does not except commands.My /etc/bash.bashrc looks like # 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)fisource /etc/profilealias login=sudo login# 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 $TERM in#xterm*|rxvt*)#    PROMPT_COMMAND='echo -ne \033]0;${USER}@${HOSTNAME}: ${PWD}\007'#    ;;#*)#    ;;#esac# enable bash completion in interactive shells#if ! shopt -oq posix; then#  if [ -f /usr/share/bash-completion/bash_completion ]; then#    . /usr/share/bash-completion/bash_completion#  elif [ -f /etc/bash_completion ]; then#    . /etc/bash_completion#  fi#fi# sudo hintif [ ! -e $HOME/.sudo_as_admin_successful ] && [ ! -e $HOME/.hushlogin ] ; then    case  $(groups)  in *\ admin\ *|*\ sudo\ *)    if [ -x /usr/bin/sudo ]; then    cat <<-EOF    To run a command as administrator (user root), use sudo <command>.
