This article will explain in detail how to use the tree command in Linux. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The Linux common command tree command lists the contents of the directory in a tree view.

The tree tree view lists the contents of the directory

Syntax tree (options) (parameters) option-list option-a # displays all files and directories. -d # displays the directory name instead of the file. -l # if you encounter a directory with a symbolic connection, directly list the original directory that the connection points to. -f # displays the full relative path name before each file or directory. -x # limits the scope to the current file system, and excludes some subdirectories under the specified directory from the search if they are stored on another file system. -L level # restricts the directory display level. -R # Rerun tree when max dir level reached. -P pattern # displays only file and directory names that match the template style. -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 # Print and format time according to the format. -o filename # Output to file instead of stdout. -File options-- Q # with "?" Instead of the control character, the file and directory names are listed. -N # lists file and directory names directly, including control characters. -Q # Quote filenames with double quotes. -p # lists permission tags. -u # lists the owner name of the file or directory, and if there is no corresponding name, the user identification number is displayed. -g # lists the name of the group to which the file or directory belongs. If there is no corresponding name, the group identification number is displayed. -s # lists file and directory sizes. -h # Print the size in a more human readable way. -- si # Like-h, but use in SI units (powers of 1000). -D # lists when the file or directory was changed. -F # adds "*", "/", "@", "|" to the execution file, directory, Socket, symbolic link, and pipe name respectively. -- 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 by the change time of files and directories. -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. -graphic option-- I # does not list file and directory names in a ladder. -A # displays the tree view using ASNI drawing characters instead of ASCII character combinations. -S # Print with CP437 (console) graphics indentation lines. -n # Turn colorization off always (- C overrides). -C # colors the list of files and directories to make it easier to distinguish between types. -XML / HTML / JSON option-- 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 # enter version information. -- help # print usage help. -# Options processing terminator. Parameter directory: execute the tree directive, which lists all files in the specified directory, including files in the subdirectory.

The instance lists the directory / private/ first-level file name

Tree / private/-L 1 / private/ ├── etc ├── tftpboot ├── tmp └── var ignore folders

Tree-I node_modules # ignore current directory folder node_modules tree-P node_modules # list current directory folder node_modules directory structure tree-P node_modules-L 2 # display directory node_modules two-tier directory tree structure tree-L 2 > / home/www/tree.txt # current directory results saved to tree.txt document ignore multiple folders

Tree-I 'node_modules | icon | font'-L 2 non-tree structure lists all files under the directory / private/

This is the end of tree-if / private/ / private/ private/a1 / private/a2 / private/etc/ private/etc/b1 / private/etc/b2 / private/tftpboot article on "how to use tree commands in Linux".
