在启动时在Ubuntu中设置环境变量(通过脚本) [英] Setting environment variable in Ubuntu at boot time (via script)

问题描述

我想在Ubuntu计算机(10.04)上设置几个环境变量，但是我想通过脚本创建它们的值，就像:

I'd like to set a couple of environment variables on an Ubuntu machine (10.04), but I want to create their value via a script, much like:

export THE_ENV_VAR=$(script_to_execute_and_use_stdout_from)

我尝试在/etc/environment中进行设置，但这仅逐字复制了rhs

I've tried setting in /etc/environment, but that only copies rhs verbatim

我尝试在启动时在/etc/init.d/中执行脚本，但这似乎不起作用.

I've tried executing a script in /etc/init.d/ at startup, but that does not seem to work.

想法?

推荐答案

您需要将导出语句写入/etc/bash.bashrc文件，该文件是系统范围的.bashrc文件，它将为所有系统用户设置环境:)

You need to write your export statement into /etc/bash.bashrc file, which is a system wide .bashrc file that will set environments for all system users :)

编辑:一种方法是在引导过程中填充缓存文件，并让用户脚本从该缓存文件中读取

Edit: One way to do this is to populate a cache file during boot, and let the user scripts read from that cached file.
