启动 ubuntu14.04 时出错

每次启动系统时我都会收到此消息：

Error found when loading /etc/profile:
/etc/profile: line 1: syntax error near unexpected token ('
/etc/profile: line 1:iamgreat# /etc/profile: system-wide.profile file for the Bourne shell(sh(1))'

As a result the session will not be configured correctly You should fix the problem as soon as feasible.

有人能帮我解决这个问题吗？这些是我当前的内容/etc/profile：

iamgreat# /etc/profile: system-wide .profile file for the Bourne shell (sh(1)) 
 # and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).
if [ "$PS1" ]; then  
  if [ "$BASH" ] && [ "$BASH" != "/bin/sh" ]; then    
  # The file bash.bashrc already sets the default PS1.    
  # PS1='\h:\w\$ '    
  if [ -f /etc/bash.bashrc ]; then      
      . /etc/bash.bashrc    fi
  else
    if [ "`id -u`" -eq 0 ]; then      
      PS1='# '
    else
       PS1='$ '    
      fi
    fi 
 fi

 # The default umask is now handled by pam_umask. 
 # See pam_umask(8) and /etc/login.defs.
if [ -d /etc/profile.d ]; then  
   for i in /etc/profile.d/*.sh; do    
      if [ -r $i ]; then
      . $i
    fi
  done  
   unset i
 fi

你/etc/profile的一团糟。即使iamgreat一开始就去除杂散，sh -n仍然抱怨语法错误。重新缩进并清理空格后，错误消失了。结果如下：

# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))
# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).
if [ "$PS1" ]; then
  if [ "$BASH" ] && [ "$BASH" != "/bin/sh" ]; then
    # The file bash.bashrc already sets the default PS1.
    # PS1='\h:\w\$ '
    if [ -f /etc/bash.bashrc ]; then
        . /etc/bash.bashrc
    fi
  else
    if [ "`id -u`" -eq 0 ]; then
      PS1='# '
    else
      PS1='$ '
    fi
  fi
fi

# The default umask is now handled by pam_umask.
# See pam_umask(8) and /etc/login.defs.
if [ -d /etc/profile.d ]; then
  for i in /etc/profile.d/*.sh; do
    if [ -r $i ]; then
      . $i
    fi
  done
  unset i
fi

export JAVA_HOME=/usr/lib/jvm/java-8-oracle

将您的内容替换/etc/profile为上面列出的代码（例如gksu gedit /etc/profile），然后您就应该再次变得好起来。

PS：比全局环境变量/etc/environment更好的地方（见最后一行）。/etc/profileJAVA_HOME

iamgreat# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))

你不应该iamgreat在那里有它。删除它。你可以使用以下命令来执行此操作：

sudo sed -i '1s/^iamgreat//' /etc/profile

或者使用编辑器。
