When you run your script normally, what happens is that your shell starts a new process, the script runs in that process, and when the script is done the process dies and control returns to your shell.
当您正常运行脚本时，发生的情况是您的 shell 启动了一个新进程，脚本在该进程中运行，当脚本完成时，该进程终止并且控制权返回到您的 shell。
All modifications that the script did to its environment die with it. The changes have no effect on the parent shell. Same if you're trying to run cdin a script and expecting the parent shell to move.
脚本对其环境所做的所有修改都会随之消失。这些更改对父 shell 没有影响。如果您尝试cd在脚本中运行并期望父 shell 移动，则相同。
To run your script in the context of your shell and not in a subprocess, use the sourceor .commands:
要在 shell 的上下文中而不是在子进程中运行脚本，请使用source或.命令：
source setAppPath.sh
. setAppPath.sh
