本操作使用場(chǎng)景：Mac OS 窑滞， Homebrew

1.安裝（tree）工具

brew install tree

2.Tree操作說明

安裝完成后良漱，可直接運(yùn)行：tree 毅弧，既可自動(dòng)生成當(dāng)前目錄文件下目錄結(jié)構(gòu)局义。

輸入 tree help 可查看tree項(xiàng)目可操作命令喜爷，具體命令結(jié)構(gòu)如下：

$ tree --help
usage: tree [-adfghilnpqrstuvxACDFNS] [-H baseHREF] [-T title ] [-L level [-R]]
 [-P pattern] [-I pattern] [-o filename] [--version] [--help] [--inodes]
 [--device] [--noreport] [--nolinks] [--dirsfirst] [--charset charset]
 [--filelimit #] [<directory list>]
 -a All files are listed(列出所有文件).
 -d List directories only(只列出目錄).
 -l Follow symbolic links like directories.(遵循象目錄這樣的符號(hào)鏈接)
 -f Print the full path prefix for each file(打印每個(gè)文件的完整路徑前綴).

 -v Sort files alphanumerically by version.(按版本對(duì)文件進(jìn)行字母數(shù)字排序)
 -r Sort files in reverse alphanumeric order.(按字母數(shù)字倒序排列文件。)
 -t Sort files by last modification time.(按上次修改時(shí)間排序文件)
 -x Stay on current filesystem only.(只保留當(dāng)前文件系統(tǒng))
 -L level Descend only level directories deep.(只向下深入到級(jí)別目錄)
 -A Print ANSI lines graphic indentation lines.(打印ANSI線圖形壓痕線)
 -S Print with ASCII graphics indentation lines.(用ASCII圖形縮進(jìn)行打印)
 -n Turn colorization off always (-C overrides).(始終關(guān)閉著色(-C覆蓋))
 -C Turn colorization on always.(始終打開彩色化)

3.常用方法舉例

3.1 指定遍歷層級(jí)

tree -L 2

("2" - 表示當(dāng)前文件夾下第幾級(jí)文件)

3.2 導(dǎo)出到指定文件 Readme.md

(*會(huì)覆蓋整個(gè)文本內(nèi)容)

tree -L 2 >README.md

3.2 過濾指定文件夾

tree -I "文件夾名"

如下過濾 node_modules

tree -I "node_modules"

過濾多文件夾

Tree -d -I "文件夾A｜文件夾B｜文件夾C"

tree -d -I "node_modules|weapp"

3.3 只顯示文件夾

tree -d 

如下 過濾node_modules?只顯示文件夾

tree -d -I "node_modules"
