系统
执行tree指令,它会列出指定目录下的所有文件,包括子目录里的文件。

功能说明:以树状图列出目录的内容。

语法:tree[-aACdDfFgilnNpqstux][-I<范本样式>][-P<范本样式>][目录...]

补充说明:执行tree指令,它会列出指定目录下的所有文件,包括子目录里的文件。

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。

NAME

tree - list contents of directories in a tree-like format.

SYNOPSIS

tree [-adfgilnopqrstuxACDFNS] [-L level [-R]] [-H baseHREF] [-T title] [-o filename] [--nolinks] [-P pattern] [-I pattern] [--inodes] [--device] [--noreport] [--dirsfirst] [--version] [--help] [directory ...]
 

DESCRIPTION

Tree is a recursive directory listing program that produces a depth indented listing of files. Color is supported ala dircolors if the LS_COLORS environment variable is set, output is to a tty, and the -C flag is used. With no arguments, tree lists the files in the current directory. When directory arguments are given, tree lists all the files and/or directories found in the given directories each in turn. Upon completion of listing all files/directories found, tree returns the total number of files and/or directories listed.

By default, when a symbolic link is encountered, the path that the symbolic link refers to is printed after the name of the link in the format:
 


    name -> real-path
 

If the `-l' option is given and the symbolic link refers to an actual directory, then tree will follow the path of the symbolic link as if it were a real directory.
 

OPTIONS

Tree understands the following command line switches:

--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 caret notation.
-N
Print non-printable characters as is instead of the default caret 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://hostname.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.

BUGS

Tree does not prune "empty" directories when the -P and -I options are used. Tree prints directories as it comes to them, so cannot accumulate information on files and directories beneath the directory it is printing. Probably more.
