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, 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 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 single 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

LS_COLORS Color information created by dircolors
