命令都不能用了。

我在虚拟机上安装了Debian，并在上面安装了JDK，在配置环境变量时，不知道是哪个文件改错了，重新登录后，除了exit、cd等少数几个能用，其它的命令（包括ls、vi、cp、rm等基本命令）都不能用了，不知道是什么原因，请大家帮帮忙，谢谢了！

输入命令按回车就会提示：
-bash : 命令 : command not found
连登录后都会出现好多提示：
-bash: dircolors: command not found
-bash: uname: command not found
-bash: uname: command not found
-bash: [: !=: unary operator expected

不要紧，使用完整的路径引用命令。
你修改了哪里的path变量？

lvzhu18

开始是在bash.bashrc里面修改的，然后又删了，又在profile里加上了。
我在修改bash.bashrc的过程中，不小心按了下Ctrl - Z，后来是fg后才退出的。
我在网上查说是那些命令都与bash.bashrc有关，可是我现在连文件都打不开。
请帮帮忙，谢谢！

用绝对路径使用命令.
楼主应该是把path变量给弄丢了

请问是哪个文件的问题，应该如何修复呢？谢谢。

path变量

lvzhu18

谢谢大家，我把/etc/profile中设置的JAVA_HOME、PATH、CLASSPATH去掉，重新登录就好了。

. /path/to/file 可以不用注销而令其生效。

在设置 java环境变量时，编辑profile文件没有写正确，导致在命令行下 ls等命令不能够识别。
在命令行下打入下面这段就可以了
export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
