Linux Talk: Tree-shaped display multilevel directory--tree

　　When blogging recently, it is occasionally necessary to visually list the file directory structure, such as Python's package structure.

So on the Internet search, found a Linux is a good tool--tree

　　Tree can visually display a multilevel directory structure.

1. Installation method

On Ubuntu directly

sudo Install Tree

2. A few more general uses:

　　1. Display the directory structure

[email protected] test]# Tree.└──level-1├──L1-file-1. TXT├──L1-file-2. Txt├──level-2-1│├──l21-file-1. Txt│├──level-3-1││└──l31-file-1. Txt│├──level-3-2││└──l32-file-1. Txt│└──level-3-3│└──l33-file-1. Txt├──level-2-2│└──l22-file-1. Txt└──level-2-37Directories,7Files

　　

　　2. Include hidden files

[Email protected] test]# tree-A.└──level-1├──L1-file-1. TXT├──L1-file-2. txt├──. L1-Hide.dat├──level-2-1│├──l21-file-1. txt│├──. L2-Hide.dat│├──level-3-1││└──l31-file-1. Txt│├──level-3-2││└──l32-file-1. Txt│└──level-3-3│└──l33-file-1. Txt├──level-2-2│└──l22-file-1. Txt└──level-2-37Directories,9Files

　　3. Depth of control (assuming 3)

[Email protected] test]# tree-l3. └──level-1├──L1-file-1. TXT├──L1-file-2. Txt├──level-2-1│├──l21-file-1. Txt│├──level-3-1│├──level-3-2│└──level-3-3├──level-2-2│└──l22-file-1. Txt└──level-2-37Directories,4Files

　　4. Show only Directories

 [[email protected] test]# tree-d.└──level - 1  ├──level -2 - 1  │  ├──level -3 -1  │  ├──level - 3 -2  │  └──level -3 -3  ├──level -2 -2  └──level -2 - 3  7  directories 

　　5. Filter the files that need to be displayed

# displays only the containing"L2"string of files and filter out the empty directory also filtered out [[email protected] test]# tree-P'*l2*'--Prune.└──level-1├──level-2-1│└──l21-file-1. Txt└──level-2-2└──l22-file-1. txt3Directories,2files# only display does not contain"L2"string of files, and will filter out the empty directory also filtered out [[email protected] test]# [[email protected] test]# tree-I.'*l2*'--Prune.└──level-1├──L1-file-1. TXT├──L1-file-2. Txt└──level-2-1├──level-3-1│└──l31-file-1. Txt├──level-3-2│└──l32-file-1. Txt└──level-3-3└──l33-file-1. txt5Directories,5Files

3. More Options

Options	Description
-A	Displays all files, including hidden files.
-D	Displays only the directory.
-L	Trace symbolic links, if linked to a directory, is treated as a directory.
-F	Displays the full path.

- L level	Controls the directory depth displayed.
-R	In the subordinate directory, execute the tree command again and add the '-o 00tree.html ' option to use with-l,-h.
-P Pattern	Only files that match the pattern (not the directory) are displayed, and simple regular expressions are supported.
-I. pattern	In contrast to-p, only files with no matching pattern are displayed.
--ignore-case	When the-p or-i option is used, the case is ignored.
--matchdirs	When the-p option is used, the file name contains the full path.
--prune	Empty directories are not displayed and are considered empty if no directories are required to be displayed after-p or-I.
--noreport	The last statistic is not displayed.
--charset CharSet	Specifies the character set.
--filelimit #	Filter out directories that have more than # of files.
--timefmt FMT	Prints the modified time of the file in the specified format.

-U	Displays the user name or UID to which the file belongs.
-G	Displays the group or GID to which the file belongs.
-S	Displays the size of the file, in bytes.
-H	Displays the size of the file, using a more user-friendly display.
--si	Displays the size of the file, similar to-H but using biggest units (1k=1000).
--du	For a directory, displays the cumulative size of all the files under it.
-D	Displays the last modified time of the file.
-F	Similar to ls-f, for different file types, add different characters at the end.
--inodes	Displays the index node of the file.
--device	Displays the device number to which the file belongs.
-V	The list of files displayed is sorted by version.
-T	The list of files displayed is sorted by the last modified time.
-C	The list of files displayed is sorted by the last state change time.
-U	Sorting is not processed.
-R	The reverse output list.
--dirsfirst	Priority display table of contents (same level)
--sort[=name]	Specifies the sort method, name (default), CTime, mtime, size, version.
-I.	Do not indent in the output.
-A	Uses the ASCII horizontal line character to denote indentation.
