在Shell脚本完成后保留环境变量 [英] Preserve environments vars after shell script finishes

问题描述

在脚本运行完毕后，如何保留从Shell脚本设置的环境变量?

How can I keep the environment variables, set from a shell script, after the script finishes running?

推荐答案

通过运行脚本无法实现.该脚本会产生它自己的子外壳，脚本完成后会丢失.

This is not possible by running the script. The script spawns it's own sub-shell which is lost when the script completes.

为了保留脚本中可能包含的 export ，请对其进行调用

In order to preserve exports that you may have in your script, call it

• 要么

. myScript.sh

或

source myScript.sh

注意.和 myScript.sh 之间的空间；还请注意，" source 是的同义词.在Bash中，但在POSIX sh 中不是，因此为了获得最大的兼容性，请使用句点"

Notice the space between the . and myScript.sh; also note that "source is a synonym for . in Bash, but not in POSIX sh, so for maximum compatibility use the period."
