tree

tree: list directories as a tree.

Synopsis

tree [-a] [-d] [-L level] [–noreport] [dir…]

Description

tree prints each dir (the working directory when none is named), then its contents as a tree, drawn with lines, descending into every directory. A symbolic link is shown as name -> target and is not followed. Names starting with a dot are left out.

At the end it reports how many directories and files it showed, for all the dirs together.

Options

-a: Shows names starting with a dot too.
-d: Shows directories only; the report then counts only directories.
-L level: Descends at most level levels (1: only the directory’s own entries). It must be greater than 0.
–noreport: Leaves the report out.

-a and -d can be joined (-ad).

Exit status

0 on success; 1 for an invalid option or level; 2 if a dir isn’t a directory (it is shown as dir [error opening dir] and the others are still listed).
