如何在 Linux 中循环目录? [英] How to loop over directories in Linux?

问题描述

我正在 Linux 上用 bash 编写脚本，需要遍历给定目录中的所有子目录名称.如何遍历这些目录(并跳过常规文件)?

I am writing a script in bash on Linux and need to go through all subdirectory names in a given directory. How can I loop through these directories (and skip regular files)?

例如:
给定的目录是 /tmp/
它有以下子目录:/tmp/A、/tmp/B、/tmp/C

我想检索 A、B、C.

I want to retrieve A, B, C.

推荐答案

cd /tmp
find . -maxdepth 1 -mindepth 1 -type d -printf '%f
'

简短说明:

• find 查找文件(很明显)

. 是当前目录，在 cd 之后是 /tmp (恕我直言，这比 /tmp 直接在 find 命令中.如果您希望在此文件夹中执行更多操作，您只有一个位置 cd 可以更改)

. is the current directory, which after the cd is /tmp (IMHO this is more flexible than having /tmp directly in the find command. You have only one place, the cd, to change, if you want more actions to take place in this folder)

-maxdepth 1 和 -mindepth 1 确保 find 只查找当前目录，不包括 . 本身在结果中

-maxdepth 1 and -mindepth 1 make sure that find only looks in the current directory and doesn't include . itself in the result

-type d 只查找目录

-printf '%f 只为每次点击打印找到的文件夹的名称(加上换行符).

-printf '%f prints only the found folder's name (plus a newline) for each hit.

等等！
