命令列出Linux目录中的所有文件夹和子文件夹

Question

I would like to check all the folders and sub-folders in a directory.

ls -R works fine, but it lists all the files in each folder and sub-folder. As a result I can't see what I want to check unless ls -R |less .

ls -R | less ls -R | less is also not a good choice because I have thousands and thousands of files in each sub-folder.

Install tree package. You can easily change max display depth of directory with -L .

For example:

$ tree -L 1 /
/
├── bin -> usr/bin
├── boot
├── dev
├── etc
├── home
├── lib -> usr/lib
├── lib64 -> usr/lib
├── lost+found
├── media
├── mnt
├── opt
├── proc
├── root
├── run
├── sbin -> usr/bin
├── srv
├── sys
├── tmp
├── usr
└── var
