# Linux tree command [ Linux Command Manual](#) The Linux tree command is used to list the contents of a directory in a tree-like diagram. Executing the tree command will list all files in the specified directory, including files in subdirectories. ### Syntax tree [directory...] **Parameter Description**: * -a Display all files and directories. * -A Use ANSI graphic characters to display the tree diagram instead of ASCII character combinations. * -C Add color to the file and directory listing to easily distinguish different types. * -d Display directory names instead of contents. * -D List the modification time of files or directories. * -f Display the full relative path name before each file or directory. * -F Append "*", "/", "=", "@", "|" to executable files, directories, Sockets, symbolic links, and pipes respectively. * -g List the group name of files or directories. If no corresponding name exists, display the group ID. * -i Do not list file or directory names in a hierarchical manner. * -L level Limit the directory display level. * -l If encountering a directory that is a symbolic link, directly list the original directory pointed to by the link. * -n Do not add color to the file and directory listing. * -N Directly list file and directory names, including control characters. * -p List permission indicators. * -P Only display file or directory names that match the pattern. * -q Use "?" to replace control characters when listing file and directory names. * -s List file or directory size. * -t Sort by the modification time of files and directories. * -u List the owner name of files or directories. If no corresponding name exists, display the user ID. * -x Limit the scope to the current file system. If some subdirectories under the specified directory are located on another file system, exclude those subdirectories from the search scope. ### Example List the current directory structure in a tree diagram.
