使用如下過程爲GitHub中的項目創建好看的目錄結構
1. 在Mac中使用如下命令安裝tree工具：
# 安裝 tree
brew install tree
2. 安裝完成之後，在項目所在的目錄中可以選擇使用如下的命令輸出項目結構：
# 使用-L參數指定遍歷層級
tree -L 2
# 將目錄的結構樹導出到文件README.md
tree -L 2 >README.md
# 在結構中只顯示文件夾
tree -d
# 過濾不想要顯示的文件或者文件夾，比如要過濾項目中的target文件夾；
tree -I pattern
tree -I “target”
# 解決中文文件名亂碼問題
tree -N
3. 具體的命令參數如下：
Yitian-MacBook-Pro:~ yitian$ tree --help
usage: tree [-acdfghilnpqrstuvxACDFJQNSUX] [-H baseHREF] [-T title ]
[-L level [-R]] [-P pattern] [-I pattern] [-o filename] [--version]
[--help] [--inodes] [--device] [--noreport] [--nolinks] [--dirsfirst]
[--charset charset] [--filelimit[=]#] [--si] [--timefmt[=]<f>]

-u Displays file owner or UID number.
-g Displays file group owner or GID number.
-s Print the size in bytes of each file.
-h Print the size in a more human readable way.
--si Like -h, but use in SI units (powers of 1000).
-D Print the date of last modification or (-c) status change.
-F Appends '/', '=', '*', '@', '|' or '>' as per ls -F.
--inodes Print inode number of each file.
--device Print device ID number to which each file belongs.
------- Sorting options -------
-v Sort files alphanumerically by version.
-t Sort files by last modification time.
-c Sort files by last status change time.
-U Leave files unsorted.
-r Reverse the order of the sort.
--dirsfirst List directories before files (-U disables).
--sort X Select sort: name,version,size,mtime,ctime.
------- Graphics options -------
-i Don't print indentation lines.
-A Print ANSI lines graphic indentation lines.
-S Print with CP437 (console) graphics indentation lines.
-n Turn colorization off always (-C overrides).
-C Turn colorization on always.
------- XML/HTML/JSON options -------

-J Prints out an JSON representation of the tree.
-H baseHREF Prints out HTML format with baseHREF as top directory.
-T string Replace the default HTML title and H1 header with string.
--nolinks Turn off hyperlinks in HTML output.
------- Input options -------
--fromfile Reads paths from files (.=stdin)
------- Miscellaneous options -------
--version Print version and exit.
--help Print usage and this help message and exit.
-- Options processing terminator.
4. 得到的目錄結構如下：
.
├── main
│ ├── java
│ │ └── cn
│ │ └── zyt
│ │ └── springbootlearning
│ │ ├── aop
│ │ ├── aspect
│ │ ├── component
│ │ ├── config
│ │ ├── controller
│ │ ├── dao
│ │ ├── domain
│ │ ├── service
│ │ │ └── impl
│ │ ├── tools
│ │ └── typehandler
│ ├── resources
│ │ ├── mapper
│ │ ├── properties
│ │ ├── static
│ │ │ ├── jquery-easyui-1.7.0
│ │ │ └── other
│ │ └── templates
│ └── webapp
│ └── WEB-INF
│ └── jsp
└── test
└── java
└── cn
└── zyt
└── springbootlearning
需要過濾多個目錄時，使用：
tree -L 10 -I "target|static"
這樣就不會輸出target和static目錄下的文件。
