提示用户使用bash脚本选择目录并读取结果 [英] Prompt user to select a directory with a bash script and read result

问题描述

我想使用bash脚本读取目录(实际上我正在使用zsh).

I want to be read a dir with a bash script (actually I am using zsh).

我想在同一目录中列出当前文件夹，并显示给用户，要求他们输入数字以选择正确的文件夹.

I want to list the current folders in the same dir and display it to the user asking them to enter a number to select the correct folder.

Please select a Folder eg, 1,2,3.
1. Folder Name 1 (this should the actual name of the folder in the dir
2. Folder 2
3. Folder 3.

我还希望能够转换输入，例如1.回到实际的文件夹名称，这样我就可以

I would like to also be able to convert the input eg 1. Back to the actual folder name so I can

cd ./$foldername/

感谢您的帮助. 干杯，约翰.

Thanks for you help. Cheers, John.

推荐答案

除非您的格式要求非常严格，否则您可以只使用 bash 的

Unless your formatting requirements are very strict, you can probably just use bash’s select construct.

以下代码将显示当前目录中所有目录的菜单，然后按chdir到所选目录:

The following code will present a menu of all the directories in the current directory and then chdir to the selected one:

printf "Please select folder:\n"
select d in */; do test -n "$d" && break; echo ">>> Invalid Selection"; done
cd "$d" && pwd
