|    |    |    |-- classes
|    |    |    +-- scripts

Answer 1

来自Unix Tree/Linux Tree的这个例子怎么样:

ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/   /' -e 's/-/|/'  

Answer 2

那个oneliner非常酷,我建议使用tree util.

bash-3.2$ mkdir -p this/is/some/nested/example
bash-3.2$ mkdir -p this/is/another/super/nested/example
bash-3.2$ mkdir -p this/is/yet/another/example
bash-3.2$ mkdir -p this/is/some/nested/other/example
bash-3.2$ tree this
this
`-- is
    |-- another
    |   `-- super
    |       `-- nested
    |           `-- example
    |-- some
    |   `-- nested
    |       |-- example
    |       `-- other
    |           `-- example
    `-- yet
        `-- another
            `-- example

13 directories, 0 files

我意识到这个问题很久以前就得到了回答,但我刚刚发现这个叫做树的程序也非常酷.

Answer 4

看RecursiveTreeIterator课

允许迭代RecursiveIterator以生成ASCII图形树.

$treeIterator = new RecursiveTreeIterator(
    new RecursiveDirectoryIterator('/path/to/dir'),
    RecursiveTreeIterator::SELF_FIRST);

foreach($treeIterator as $val) echo $val, PHP_EOL;

输出将是这样的(在我的机器上使用c:\​​ php):

|-c:\php5\cfg
|-c:\php5\data
| |-c:\php5\data\Base
| | \-c:\php5\data\Base\design
| |   |-c:\php5\data\Base\design\class_diagram.png
| |   \-c:\php5\data\Base\design\design.txt
| |-c:\php5\data\ConsoleTools
| | \-c:\php5\data\ConsoleTools\design
| |   |-c:\php5\data\ConsoleTools\design\class_diagram.png
| |   |-c:\php5\data\ConsoleTools\design\console.png
| |   |-c:\php5\data\ConsoleTools\design\console.xml

本身不是一个库，但这个小实用程序可以方便地在不离开浏览器的情况下生成快速树图： https: //tree.nathanfriend.io/

与--tree的exa表现出色：

exa --tree ~/tmp/public/

<dir>
??? aboutme
?  ??? index.html
??? atrecurse
?  ??? index.html
??? base.css
??? html5
?  ??? cat-and-mouse
?  ??? frantic
?     ??? css
?     ?  ??? main.css
