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.

--help

Outputs a verbose usage listing.

--version

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.

-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) and `|' separates alternate patterns.

-I pattern

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

--noreport

Omits printing of the file and directory report at the end of the tree listing.

-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.

--inodes

Prints the inode number of the file or directory

--device

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 caret notation.

-r

Sort the output in reverse alphabetic order.

-t

Sort the output by last modification time instead of alphabetically.

--dirsfirst

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 lines.

-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.

-L level

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.

-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: 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.

-T title

-T title

Sets the title and H1 header string in HTML output mode.
