破坏了我的 centos 路径设置
我错误地通过添加错误的路径破坏了我的 centos 路径设置。我添加了以下内容：
PATH=/usr/local/jdk1.6.0/bin
export PATH
到 /etc/profile/bashrc ，现在所有命令都消失了。
有人可以帮我恢复我的系统吗？
提前致谢。

设置路径而不破坏路径的一种方法是：
export PATH=/usr/local/jdk1.6.0/bin:$PATH简短的解释。当您想向路径添加新内容时，应保留旧路径设置。您所做的是将路径设置为仅指向 /usr/local/jdk1.6.0/bin。这就是为什么除了 /usr/local/jdk1.6.0/bin 中找到的命令之外的所有其他命令都“消失了”。没有什么是真正“消失”的。你只需要重置你的路径。只需打开一个新的 shell/终端实例或简单地注销/登录并使用更正确的方式设置您的路径。
One way of setting your path without breaking it is:
export PATH=/usr/local/jdk1.6.0/bin:$PATHA short explanation. When you want to add something new to your path, you should keep the old path settings. What you did was to set the path to point only to /usr/local/jdk1.6.0/bin. That's why all the other commands except from the ones found in /usr/local/jdk1.6.0/bin are "gone". Nothing is really "gone". You just need to reset your path. Just open a new shell/terminal instance or simply logout/login and set your path using a more proper way.
