On Macs, defining environment variables in the environment.plist will allow you to use environment variables in Emacs.app. On Linux, is there such an equivalent?

I don't want to use the environment variables in one of the shell or terminal emulators but also for find-file (C-x C-f), shell-command (C-!), etc. and I have a lot of paths defined as environment variables that would be helpful here. For instance, finding a file with find-file can be $WORK/projectname and so on.

I suppose the most straightforward way is to use setenv within .emacs, but as I have a lot of such variables it would be better if I could define it once in an external file and have Emacs read it in.

Edit: Sorry for the confusion. This question is specifically addressing issue of Emacs access, as variables defined in ~/.bashrc is not available to Emacs until shell, eshell, or term is invoked.

这里是一个脚本，它定义了几个环境变量，由 Emacs 以批处理模式读取

从 lisp 获取 $HOME 例如使用 (getenv "HOME")

为了能够访问您的变量，您.bashrc需要从 bash shell 启动 emacs。如果您只是单击一个图标，.bashrc则不会读取该图标，并且您将无权访问您的变量。

如果您绝对无法从 bash shell 启动 emacs，请找到一个由您的桌面环境加载的 init 文件。就我而言，它是.xsession。我在其中导出的任何变量都可用于 emacs。

要访问环境变量，请使用getenv.

如果您在 ~/.bashrc 中定义环境变量，则它们在用户 shell 中可用于所有命令。正确的语法是：

export VARIABLE="value"

您可以.bashrc在您的主目录中编辑您的，您可以在其中添加您自己的别名、定义环境变量并为您的自定义脚本添加路径。
