Dutree – Linux上的命令行磁盘使用情况分析工具
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 Updating `https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index` index Downloaded dutree v0.2.16 (registry `https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index`) Downloaded 1 crate (638.0 KB) in 0.37s Installing dutree v0.2.16 Downloaded signal-hook v0.1.16 (registry `https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index`) Downloaded terminal_size v0.1.13 (registry `https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index`) Downloaded thread_local v1.0.1 (registry `https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index`) Downloaded signal-hook-registry v1.2.2 (registry `https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index`) Downloaded unicode-width v0.1.8 (registry `https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index`) Downloaded memchr v2.3.4 (registry `https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index`) Downloaded regex-syntax v0.6.21 (registry `https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index`) Downloaded aho-corasick v0.7.14 (registry `https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index`) Downloaded regex v1.4.2 (registry `https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index`) Downloaded libc v0.2.80 (registry `https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index`) Downloaded lazy_static v1.4.0 (registry `https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index`) Downloaded getopts v0.2.21 (registry `https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index`) Downloaded unicode-segmentation v1.6.0 (registry `https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index`) Downloaded 13 crates (1.4 MB) in 0.43s Compiling libc v0.2.80 Compiling memchr v2.3.4 Compiling lazy_static v1.4.0 Compiling unicode-width v0.1.8 Compiling regex-syntax v0.6.21 Compiling unicode-segmentation v1.6.0 Compiling thread_local v1.0.1 Compiling getopts v0.2.21 Compiling signal-hook-registry v1.2.2 Compiling terminal_size v0.1.13 Compiling aho-corasick v0.7.14 Compiling signal-hook v0.1.16 Compiling regex v1.4.2 Compiling dutree v0.2.16 Finished release [optimized] target(s) in 1m 35s 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
