# The `tree` command
|
|
|
|
The `tree` command in Linux recursively lists directories as tree structures. Each listing is indented according to its depth relative to root of the tree.
|
|
|
|
### Examples:
|
|
|
|
1. Show a tree representation of the current directory.
|
|
|
|
```
|
|
tree
|
|
```
|
|
|
|
2. -L NUMBER limits the depth of recursion to avoid display very deep trees.
|
|
|
|
```
|
|
tree -L 2 /
|
|
```
|
|
|
|
### Syntax:
|
|
|
|
```
|
|
tree [-acdfghilnpqrstuvxACDFQNSUX] [-L level [-R]] [-H baseHREF] [-T title]
|
|
[-o filename] [--nolinks] [-P pattern] [-I pattern] [--inodes]
|
|
[--device] [--noreport] [--dirsfirst] [--version] [--help] [--filelimit #]
|
|
[--si] [--prune] [--du] [--timefmt format] [--matchdirs] [--from-file]
|
|
[--] [directory ...]
|
|
```
|
|
|
|
