你也想要生成这个目录树层结构吗？，按下面操作即可：
├── build ├── config ├── docs │ └── static│ ├── css │ └── js ├── src │ ├── assets │ ├── components │ ├── store │ │ └── modules │ └── views │ ├── book │ └── movie └── static
1. mac 下使用 brew包管理工具安装 tree
brew install tree
2. 安装成功后，直接在终端使用，使用 --help 查看帮助信息
tree --help
看到如下功能
tree --help 10:06:14usage: 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>] [--sort[=]<name>] [--matchdirs] [--ignore-case] [--] [<directory list>] ------- Listing options ------- -a All files are listed. -d List directories only. -l Follow symbolic links like directories. -f Print the full path prefix for each file. -x Stay on current filesystem only. -L level Descend only level directories deep. -R Rerun tree when max dir level reached. -P pattern List only those files that match the pattern given. -I pattern Do not list files that match the given pattern. --ignore-case Ignore case when pattern matching. --matchdirs Include directory names in -P pattern matching. --noreport Turn off file/directory count at end of tree listing. --charset X Use charset X for terminal/HTML and indentation line output. --filelimit # Do not descend dirs with more than # files in them. --timefmt <f> Print and format time according to the format <f>. -o filename Output to file instead of stdout. -------- File options --------- -q Print non-printable characters as '?'. -N Print non-printable characters as is. -Q Quote filenames with double quotes. -p Print the protections for each file. -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 ------- -X Prints out an XML representation of the tree. -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. ---- Miscellaneous options ---- --version Print version and exit. --help Print usage and this help message and exit. -- Options processing terminator.
3. 输出你的树层目录结构
cd 目标文件夹路径
然后 tree 一下，会将该层级下所有文件都遍历了输出，不管层级多深
4. 常用技巧
我们可以在目录遍历时使用 -L 参数指定遍历层级
tree -L 2
如果你想把一个目录的结构树导出到文件 Readme.md ,可以这样操作
tree -L 2 >README.md //然后我们看下当前目录下的 README.md 文件
只显示文件夹；
tree -d
显示项目的层级，n表示层级数。例：显示项目三层结构，tree -l 3；
tree -L n
tree -I pattern 用于过滤不想要显示的文件或者文件夹。比如要过滤项目中的node_modules文件夹；
tree -I “node_modules”
