如何在shell脚本运行“CD”，呆在那里的脚本结束后？ [英] How to run 'cd' in shell script and stay there after script finishes?

问题描述

我在shell脚本中使用更改目录（庆典）

I used 'change directory' in my shell script (bash)

#!/bin/bash
alias mycd='cd some_place'
mycd
pwd

PWD 打印 some_place 正确，但脚本完成后，我当前的工作目录并没有改变。

pwd prints some_place correctly, but after the script finished my current working directory doesn't change.

是否有可能通过脚本来改变我的路径？

Is it possible to change my path by script?

推荐答案

您需要将源文件为：

. myfile.sh

或

source myfile.sh

没有采购的变化在子壳和未在其中调用脚本的父外壳会发生。但是，当你源文件，就好像在命令行中键入文件中的行执行。

Without sourcing the changes will happen in the sub-shell and not in the parent shell which is invoking the script. But when you source a file the lines in the file are executed as if they were typed at the command line.
