Bash脚本更改父Shell目录 [英] Bash script to change parent shell directory

问题描述

我要做什么

我已经创建了一个外壳脚本，并将其添加到$ PATH中，该脚本将下载并为新的 Laravel 项目进行所有设置. .我希望通过将终端目录更改为新的项目文件夹来结束脚本.

I've created a shell script that I've added to my $PATH that will download and get everything setup for a new Laravel project. I would like the script to end by changing my terminal directory into the new project folder.

据我目前的了解，它只是更改脚本实际运行所在的子shell的目录.我似乎无法弄清楚该如何做.任何帮助表示赞赏.谢谢！

From what I understand right now currently it's only changing the directory of the sub shell where the script is actually running. I can't seem to figure out how to do this. Any help is appreciated. Thank you!

推荐答案

使用shell 函数来前端脚本

Use a shell function to front-end your script

setup () {
  # first, call your big script.
  # (It could be open-coded here but that might be a bit ugly.)

  # then finally...

  cd someplace
}

将shell函数放在shell启动文件中.

Put the shell function in a shell startup file.
