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。
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
系统环境
安装
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:
[root@localhost ~]# cargo install dutree

Installing /root/.cargo/bin/dutree
Installed package `dutree v0.2.16` (executable `dutree`)
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
实例
目录深度
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/
排除某个文件
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。
进度条使用ASCII字符显示
可以使用ASCII字符#号来代替默认的进度条:
[root@localhost ~]# dutree -d1 -A /root
