Linux下使用tree命令以樹形結構顯示資料夾目錄結構

tree命令功能說明：以樹狀圖列出目錄的內容。

如：

tree 以樹狀圖顯示所有檔案

tree -L N 以樹狀圖顯示所有檔案，子資料夾顯示到第 N 層

Ubuntu安裝tree命令

sudo apt-get install tree

tree命令常用使用方法

(1) 顯示當前目錄的樹形結構

linuxidc@linuxidc:~/桌面/www.linuxidc.com/linuxidc.com$ tree

└── 教學重要說明及更新連結點選這個文字.txt

2 directories, 7 files

(2) 只檢視當前第一級的目錄和檔案

$ tree -L 1

(3) 只檢視當前第二級的目錄和檔案

$ tree -L 2

(4) 只檢視當前第N級的目錄和檔案

$ tree -L N

(5) 把目錄結構資訊儲存到文字中

$ tree -L 2 > linuxidc.com.txt
