 语  法:tree [-aACdDfFgilnNpqstux][-I <范本样式>][-P <范本样式>][目录...]
参  数:
-a   显示所有文件和目录。
-A   使用ASNI绘图字符显示树状图而非以ASCII字符组合。
-C   在文件和目录清单加上色彩,便于区分各种类型。
-d   显示目录名称而非内容。
-D   列出文件或目录的更改时间。
-f   在每个文件或目录之前,显示完整的相对路径名称。
-F   在执行文件,目录,Socket,符号连接,管道名称名称,各自加上"*","/","=","@","|"号。
-g   列出文件或目录的所属群组名称,没有对应的名称时,则显示群组识别码。
-i   不以阶梯状列出文件或目录名称。
-I<范本样式>   不显示符合范本样式的文件或目录名称。
-l   如遇到性质为符号连接的目录,直接列出该连接所指向的原始目录。
-n   不在文件和目录清单加上色彩。
-N   直接列出文件和目录名称,包括控制字符。
-p   列出权限标示。
-P<范本样式>   只显示符合范本样式的文件或目录名称。
-q   用"?"号取代控制字符,列出文件和目录名称。
-s   列出文件或目录大小。
-t   用文件和目录的更改时间排序。
-u   列出文件或目录的拥有者名称,没有对应的名称时,则显示用户识别码。
-x   将范围局限在现行的文件系统中,若指定目录下的某些子目录,其存放于另一个文件系统上,则将该子目录予以排除在寻找范围外。



List the contents of directories in a tree-like format.


tree [-adfgilnopqrstuxACDFNS] [-L level [-R]] [-H baseHREF] [-T title] [-o filename] [--nolinks] [-P pattern] [-I pattern] [--inodes] [--device] [--noreport] [--dirsfirst] [--version] [--help] [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 Makes tree not print the indentation lines, useful when used in conjunction with the -f option. -l Follows symbolic links if they point to directories, as if they were directories. Symbolic links that will result in recursion are avoided when detected. -x Stay on the current file-system only. Ala find -xdev. -P pattern List only those files that match the wild-card 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 wild-card pattern. --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 along 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 filenames 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, over-ridden 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 will eventually be 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 wish to use colors via CCS 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 filename Send output to filename.



Simply running the command without any option will give a tree output of the current directory and alls sub directories. Therefore if you're at root it's not a good idea to run this command alone otherwise it will list every file and directory on the computer.

tree -L 1

List the directories and files in the current directory. Below is an example of what this may look like.
