Dutree – Linux上的命令行磁盘使用情况分析工具

dutree的特性：

• 彩色输出
• 分层显示文件系统
• 用户可以聚合小文件
• 用户可以排除文件或目录
• 用户可以比较不同的目录
• 可靠性和速度快

Centos7

需要先安装cargo包管理器：

[root@localhost ~]# yum -y install cargo

其次配置cargo的仓库地址，因为默认使用国外源，下载速度超慢：

进入$HOME/.cargo创建config配置文件：

[root@localhost ~]# cd $HOME/.cargo
[root@localhost .cargo]# touch config

将下面内容复制到config配置文件中：

[source.crates-io]
registry = "https://github.com/rust-lang/crates.io-index"

# 替换成速度比较快的镜像源，这里使用上海交大的。
replace-with = 'sjtu'

# 清华大学
[source.tuna]
registry = "https://mirrors.tuna.tsinghua.edu.cn/git/crates.io-index.git"

# 上海交通大学
[source.sjtu]
registry = "https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index"

# rustcc社区
[source.rustcc]
registry = "git://crates.rustcc.cn/crates.io-index"

开始安装dutree吧：

warning: be sure to add `/root/.cargo/bin` to your PATH to be able to run the installed binaries

看到上面最后一个warning提示，需要将/root/.cargo/bin目录添加到PATH环境变量中：

[root@localhost ~]# echo "export PATH=$PATH:/root/.cargo/bin" >> ~/.bashrc 
[root@localhost ~]# source ~/.bashrc 

现在可以使用dutree了

通过-d选项，加上数字，查看一层目录或者多层目录，下面是查看/root用户家目录的，查查看一层目录：

[root@localhost ~]# dutree -d1 ./

下面是查看/root家目录最多3层目录：

[root@localhost ~]# dutree -d3 ./

如果不限制目录层数，可以不加-d选项，下面查看/root/test目录：

[root@localhost ~]# dutree test/

要排除与文件或目录名称匹配的内容，请使用-x选项。下面排除test目录中包括dir1的项目：

[root@localhost ~]# dutree -x dir1 test/

使用-H选项，可以排除隐藏文件：

[root@localhost ~]# dutree -H

可以看到隐藏文件没有列出来。

可以使用ASCII字符#号来代替默认的进度条：

[root@localhost ~]# dutree -d1 -A /root

Dutree是Durep和Tree的组合。Durep用图表创建磁盘使用情况报告，这使我们能够确定哪些目录使用了最多的空间。尽管durep可以产生类似于du的文本输出，但其真正的功能是能够将报告存储在文件中。Tree是目录显示程序，它以树状结构在终端上递归列出目录。
