永久设置CLASSPATH [英] Setting CLASSPATH permanently

问题描述

为了设置我的classpath环境变量，我正在运行以下命令：

In order to set my classpath environment variable, I'm running the following command:

export CLASSPATH=/path/to/appropriate/dir

为了检查这是否正确设置，我将输入

In order to check that this was correctly set, I'll type

echo $CLASSPATH

并返回/ path / to / proper / dir。

and am returned /path/to/appropriate/dir.

然而，当我在终端中打开一个新的标签或窗口时

However, when I open up a new tab or window in the terminal

echo $CLASSPATH

什么都不返回。这里发生了什么？

returns nothing. What's going on here?

推荐答案

您在终端中设置的变量仅对该终端有效。你应该做的是，在你的〜/ .bashrc 文件中导出变量，该文件是为每个终端加载的。所以，在 .bashrc 文件中添加该语句，你就没事了。

The variable you set in a terminal, is valid only for that terminal. What you should do is, export the variable in your ~/.bashrc file, which is loaded for each terminal. So, add that statement in the .bashrc file, and you'll be fine.

你也可以导出来自〜/ .bash_profile 文件的变量，将为登录shell加载。

You can also export the variable from ~/.bash_profile file, which will be loaded for login shells.
