You can make your own primitive "tree" ( for fun :) )
您可以制作自己的原始“树”（为了好玩:)）
#!/bin/bash
# only if you have bash 4 in your CentOS system
shopt -s globstar
for file in **/*
do
slash=${file//[^\/]}
case "${#slash}" in
0) echo "|-- ${file}";;
1) echo "| |-- ${file}";;
2) echo "| | |-- ${file}";;
esac
done

You have tree in the base repo.
你在基础仓库中有树。
Show it (yum list package-name):
显示它（yum list package-name）：
# yum list tree
Available Packages
tree.i386 1.5.0-4 base
Install it:
安装它：
yum install tree
(verified on CentOS 5 and 6)
（已在 CentOS 5 和 6 上验证）

If tree is not installed on your Centos system (I typically recommend server setups to use minimal install disk anyhow) you should type the following at your command line:
如果你的 Centos 系统上没有安装 tree（我通常建议服务器设置使用最少的安装磁盘）你应该在你的命令行中输入以下内容：
# yum install tree -y
If this doesn't install it's because you don't have the proper repository. I would use the Dag Wieers repository:
如果这没有安装，那是因为您没有正确的存储库。我会使用 Dag Wieers 存储库：
http://dag.wieers.com/rpm/FAQ.php#B
http://dag.wieers.com/rpm/FAQ.php#B
After that you can do your install:
之后，您可以进行安装：
# yum install tree -y
Now you're ready to roll. Always read the man page: http://linux.die.net/man/1/tree
现在你准备好开始了。始终阅读手册页：http: //linux.die.net/man/1/tree
So quite simply the following will return a tree:
所以很简单，以下将返回一棵树：
# tree
Alternatively you can output this to a text file. There's a ton of options too.. Again, read your man page if you're looking for something other than default output.
或者，您可以将其输出到文本文件。还有很多选项。如果您正在寻找除默认输出之外的其他内容，请再次阅读您的手册页。
# tree > recursive_directory_list.txt
(^^ in a text file for later review ^^)
（^^ 在文本文件中供以后查看 ^^）

Since treeis not installed by default in CentOS ...
由于tree在 CentOS 中默认未安装...
[user@CentOS test]$ tree
-bash: tree: command not found
[user@CentOS test]$
You can also use the following lscommand to produce almost similar output with tree
您还可以使用以下ls命令产生几乎相似的输出tree
ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/ /' -e 's/-/|/'
Example:
例子：
[user@CentOS test]$ ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/ /' -e 's/-/|/'
.
|-directory1
|-directory2
|-directory3
[user@CentOS directory]$
