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

Tree is a recursive directory listing program that produces a depth
indented listing of files, which is colorized ala dircolors if the
LS_COLORS environment variable is set and output is to tty. 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
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.
Tree understands the following command line switches:
--help Outputs a verbose usage listing.
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.
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.
Omits printing of the file and directory report at the end of
the tree listing.
-p Print the file type and permissions for each file (as per ls
-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), terrabytes (T), petabytes (P) and exabytes (E).
-u Print the username, or UID # if no username is available, of the
-g Print the group name, or GID # if no group name is available, of
-D Print the date of the last modification time for the file
Prints the inode number of the file or directory
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
-v Sort the output by version.
-r Sort the output in reverse alphabetic order.
-t Sort the output by last modification time instead of
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
-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.
Max display depth of the directory tree.
Do not descend directories that contain more than # entries.
-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.
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.
Sets the title and H1 header string in HTML output mode.
Set the character set to use when outputting HTML and for line
Turns off hyperlinks in HTML output.
Send output to filename.
/etc/DIR_COLORS System color database.
~/.dircolors Users color database.
LS_COLORS Color information created by dircolors
TREE_CHARSET Character set for tree to use in HTML mode.
LC_CTYPE Locale for filename output.

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.
The -h option rounds to the nearest whole number unlike the ls
implementation of -h which rounds up always. The IEC standard names
for powers of 2 cooresponding to metric powers of 10 (KiBi, et al.) are
Pruning files and directories with the -I, -P and --filelimit options
will lead to incorrect file/directory count reports.
