将 Lubuntu 从 12.10 升级到 13.04 后，我遇到了这个问题。

我按Ctrl+ Alt+ 1，输入登录名，密码，等待两秒钟，然后得到：?: command not found"。在此消息之后，我可以毫无问题地键入命令，但它是什么？

echo $PATH
/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/vitaly/bin:/usr/java/jdk1.7.0_17/bin

我的.bashrc文件是：

echo $PATH
/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/vitaly/bin:/usr/java/jdk1.7.0_17/bin

我的.profile文件是：

# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples

# If not running interactively, don't do anything
case $- in
    *i*) ;;
      *) return;;
esac
