昨天不小心修改了/ect/bashrc和/ect/profile后，启动时进入不了xwindow
请各位高手帮忙看看是什么原因！！！非常感谢！！
/ect/bashrc内容如下：

# /etc/bashrc

# System wide functions and aliases
# Environment stuff goes in /etc/profile

# by default, we want this to get set.
# Even for non-interactive, non-login shells.

if [ "`id -gn`" = "`id -un`" -a `id -u` -gt 99 ]; then
       umask 002
else
       umask 022
fi

# are we an interactive shell?
if [ "$PS1" ]; then
   case $TERM in
       xterm*)
           PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME}: ${PWD}\007"'
           ;;
       *)
           ;;
   esac   
   [ "$PS1" = "\\s-\\v\\\$ " ] && PS1="[\u@\h \W]\\$ "
        
   if [ -z "$loginsh" ]; then # We're not a login shell
       for i in /etc/profile.d/*.sh; do
           if [ -x $i ]; then
               . $i
