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

SYNOPSIS
       tree [ -adfgilnpqstuxACDFN ] [ -P pattern ] [ -I pattern ] [ directory ... ]

DESCRIPTION
       Tree  is  a  recursive  directory listing program that produces a depth indented listing of files.  Color is supported ala dircolors if the
       LS_COLORS environment variable is set, output is to a tty, and the -C flag is used.  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
       format:

	   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.

OPTIONS
       Tree understands the following command line switches:

       -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.

       -x     Stay on the current file-system only.  Ala find -xdev.

       -P pattern
	      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 sin-
	      gle character not listed in brackets).

       -I pattern
	      Do not list those files that match the wild-card pattern.

       -p     Print the protections for each file (as per ls -l).

       -s     Print the size of each file along with the name.

       -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.

       -D     Print the date of the last modification time for the file listed.

       -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 caret notation.

       -t     Sort the output by last modification time instead of alphabetically.

       -n     Turn colorization off always, over-ridden by the -C option.

       -C     Turn colorization on always, unless 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 lines.

FILES
       /etc/DIR_COLORS		System color database.
       ~/.dircolors		Users color database.

ENVIRONMENT
