tree 命令，是一个递归目录列表程序，它生成一个深度缩进的文件列表（如果设置了 LS_COLORS 环境变量，它会被着色）并且输出到 tty。 没有参数，树列出当前目录中的文件。 当给出目录参数时，树依次列出在给定目录中找到的所有文件和 / 或目录。 tree 然后返回列出的文件和 / 或目录的总数。
默认情况下，当遇到符号链接时，符号链接所指的路径以格式打印在链接名称之后：
name -> real-path
tree [-adfgilnopqrstuxACDFNS] [-L level [-R]] [-H baseHREF] [-T title]
[-o file name] [--nolinks] [-P pattern] [-I pattern] [--inodes]
[--device] [--noreport] [--dirsfirst] [--version] [--help]
[--filelimit #] [--si] [--prune] [--du] [--timefmt format]
[directory ...]
--help Outputs a verbose usage listing. --version Outputs the version of tree. -a All files are printed. By default, tree does not print hidden files (those beginning with a dot `.'). In no event does tree print the file system constructs `.' (current directory) and `..' (previous directory). -d List directories only. -f Prints the full path prefix for each file. -i Tree does not print the indentation lines. Useful when used in conjunction with the -f option. -l Follows symbolic links to directories as if they were directories. Links that would result in a recursive loop are avoided. -x Stay on the current file system only, as with find -xdev. -P pattern List only those files that match the wildcard pattern. Note: you must use the -a option to also consider those files beginning with a dot `.' for matching. Valid wildcard operators are `*' (any zero or more characters), `?' (any single character), `[...]' (any single character listed between brackets (optional - (dash) for character range may be used: ex: [A-Z]), and `[^...]' (any single character not listed in brackets) and `|' separates alternate patterns. -I pattern Do not list those files that match the wildcard pattern. --prune Makes tree prune empty directories from the output, useful when used in conjunction with -P or -I. --filelimit # Do not descend directories that contain more than # entries. --timefmt format Prints (implies -D) and formats the date according to the format string which uses the strftime syntax. --noreport Omits printing of the file and directory report at the end of the tree listing. -p Print the protections for each file (as per ls -l). -s Print the size of each file with the name. -u Print the username, or UID # if no username is available, of the file. -g Print the group name, or GID # if no group name is available, of the file. -D Print the date of the last modification time for the file listed. --inodes Prints the inode number of the file or directory --device Prints the device number to which the file or directory belongs -F Append a `/' for directories, a `=' for socket files, a `*' for executable files and a `|' for FIFO's, as per ls -F -q Print non-printable characters in file names as question marks instead of the default carrot notation. -N Print non-printable characters as is instead of the default carrot notation. -r Sort the output in reverse alphabetic order. -t Sort the output by last modification time instead of alphabetically. --dirsfirst List directories before files. -n Turn colorization off always, overridden by the -C option. -C Turn colorization on always, using built-in color defaults if the LS_COLORS environment variable is not set. Useful to colorize output to a pipe. -A Turn on ANSI line graphics hack when printing the indentation lines. -S Turn on ASCII line graphics (useful when using linux console mode fonts). This option is now equivalent to `--charset=IBM437' and eventually is depreciated. -L level Max display depth of the directory tree. -R Recursively cross down the tree each level directories (see -L option), and at each of them execute tree again adding `-o 00Tree.html' as a new option. -H baseHREF Turn on HTML output, including HTTP references. Useful for ftp sites. baseHREF gives the base ftp location when using HTML output. That is, the local directory may be `/local/ftp/pub', but it must be referenced as `ftp://host-name.organization.domain/pub' (baseHREF should be `ftp://hostname.organization.domain'). Hint: don't use ANSI lines with this option, and don't give more than one directory in the directory list. If you want to use colors via CSS stylesheet, use the -C option in addition to this option to force color output. -T title Sets the title and H1 header string in HTML output mode. --charset charset Set the character set to use when outputting HTML and for line drawing. --nolinks Turns off hyperlinks in HTML output. -o file name Send output to file name.
tree 显示高达 num 级深度的文件和目录（其中 1 表示当前目录）：
tree -L num -------------------- $ tree -L 2 . ├── conf │ └── nutcracker.yml ├── sbin │ └── nutcracker ├── share │ └── man └── twemproxy.log 4 directories, 3 files
tree 仅显示目录：
tree -d
--------------------
$ tree -d
.
├── conf
├── sbin
└── share
└── man
└── man8
5 directories
tree 也显示隐藏文件：
tree -a -------------------- $ tree -a . ├── conf │ └── nutcracker.yml ├── sbin │ └── nutcracker ├── share │ └── man │ └── man8 │ └── nutcracker.8 └── twemproxy.log 5 directories, 4 files
tree 打印没有缩进线的树，而是显示完整路径（使用 -N 不转义空格和特殊字符）：
tree -i -f -------------------- $ tree -i -f . ./conf ./conf/nutcracker.yml ./sbin ./sbin/nutcracker ./share ./share/man ./share/man/man8 ./share/man/man8/nutcracker.8 ./twemproxy.log 5 directories, 4 files
tree 以人类可读的格式打印旁边每个节点的大小：
tree -s -h -------------------- $ tree -s -h . ├── [ 28] conf │ └── [ 471] nutcracker.yml ├── [ 24] sbin │ └── [885K] nutcracker ├── [ 17] share │ └── [ 18] man │ └── [ 26] man8 │ └── [2.1K] nutcracker.8 └── [ 0] twemproxy.log 5 directories, 4 files
tree 使用通配符 (glob) 模式过滤树：
tree -P *.txt
--------------------
$ tree -P *.yml
.
├── conf
│ └── nutcracker.yml
├── sbin
└── share
└── man
└── man8
5 directories, 1 file
tree 忽略与通配符 (glob) 模式匹配的条目：
tree -I *.txt -------------------- $ tree -I *.yml . ├── conf ├── sbin │ └── nutcracker ├── share │ └── man │ └── man8 │ └── nutcracker.8 └── twemproxy.log 5 directories, 3 files
