|-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.|
|-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.|
|-f||Prints the full path prefix for each file.|
|-x||Stay on the current file-system only. Ala find -xdev.|
|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.|
|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.|
|Do not list those files that match the wild-card pattern.|
|.TP --ignore-case If a match pattern is specified by the -P or -I option, this will cause the pattern to match without regards to the case of each letter.|
|If a match pattern is specified by the -P option, this will cause the pattern to be applied to directory names (in addition to filenames). In the event of a match on the directory name, matching is disabled for the directorys contents. If the --prune option is used, empty folders that match the pattern will not be pruned.|
|Makes tree prune empty directories from the output, useful when used in conjunction with -P or -I. See BUGS AND NOTES below for more information on this option.|
|Omits printing of the file and directory report at the end of the tree listing.|
|Set the character set to use when outputting HTML and for line drawing.|
|Do not descend directories that contain more than # entries.|
|Prints (implies -D) and formats the date according to the format string which uses the strftime(3) syntax.|
|Send output to filename.|
-q Print non-printable characters in filenames as question marks instead of the default. -N Print non-printable characters as is instead of as escaped octal numbers. -Q Quote the names of files in double quotes. -p Print the file type and permissions for each file (as per ls -l). -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. -s Print the size of each file in bytes along with the name. -h Print the size of each file but in a more human readable way, e.g. appending a size letter for kilobytes (K), megabytes (M), gigabytes (G), terabytes (T), petabytes (P) and exabytes (E). --si Like -h but use SI units (powers of 1000) instead. --du For each directory report its size as the accumulation of sizes of all its files and sub-directories (and their files, and so on). The total amount of used space is also given in the final report (like the du -c command.) This option requires tree to read the entire directory tree before emitting it, see BUGS AND NOTES below. Implies -s. -D Print the date of the last modification time or if -c is used, the last status change time for the file listed. -F Append a / for directories, a = for socket files, a * for executable files, a > for doors (Solaris) and a | for FIFOs, as per ls -F --inodes Prints the inode number of the file or directory --device Prints the device number to which the file or directory belongs
-v Sort the output by version. -t Sort the output by last modification time instead of alphabetically. -c Sort the output by last status change instead of alphabetically. Modifies the -D option (if used) to print the last status change instead of modification time. -U Do not sort. Lists files in directory order. Disables --dirsfirst. -r Sort the output in reverse order. This is a meta-sort that alter the above sorts. This option is disabled when -U is used. --dirsfirst List directories before files. This is a meta-sort that alters the above sorts. This option is disabled when -U is used. --sort[=]<name> Sort the output by name (as per ls): name (default), ctime (-c), mtime (-t), size or version (-v).
-i Makes tree not print the indentation lines, useful when used in conjunction with the -f option. Also removes as much whitespace as possible when used with the -J or -x options. -A Turn on ANSI line graphics hack when printing the indentation lines. -S Turn on CP437 line graphics (useful when using Linux console mode fonts). This option is now equivalent to --charset=IBM437 and may eventually be depreciated. -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.
-X Turn on XML output. Outputs the directory tree as an XML formatted file. -J Turn on JSON output. Outputs the directory tree as an JSON formatted array. -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: dont use ANSI lines with this option, and dont give more than one directory in the directory list. If you wish to use colors via CCS style-sheet, 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. --nolinks Turns off hyperlinks in HTML output.
--help Outputs a verbose usage listing. --version Outputs the version of tree. -- Option processing terminator. No further options will be processed after this.
/etc/DIR_COLORS System color database.
~/.dircolors Users color database.
LS_COLORS Color information created by dircolors
TREE_COLORS Uses this for color information over LS_COLORS if it is set.
TREE_CHARSET Character set for tree to use in HTML mode.
LC_CTYPE Locale for filename output.
LC_TIME Locale for timefmt output, see strftime(3).
TZ Timezone for timefmt output, see strftime(3).

Tree does not prune "empty" directories when the -P and -I options are used by default. Use the --prune option.
The -h and --si options round to the nearest whole number unlike the ls implementations which rounds up always.
Pruning files and directories with the -I, -P and --filelimit options will lead to incorrect file/directory count reports.
The --prune and --du options cause tree to accumulate the entire tree in memory before emitting it. For large directory trees this can cause a significant delay in output and the use of large amounts of memory.
The timefmt expansion buffer is limited to a ridiculously large 255 characters. Output of time strings longer than this will be undefined, but are guaranteed to not exceed 255 characters.
XML/JSON trees are not colored, which is a bit of a shame.
