在 Linux 中，名称与正则表达式匹配的文件的磁盘使用情况? [英] Disk usage of files whose names match a regex, in Linux?

问题描述

因此，在许多情况下，我想知道我的磁盘空间有多少被什么使用，所以我知道要摆脱什么、转换为另一种格式、存储在其他地方(例如数据 DVD)、移动到另一个分区等.在这种情况下，我正在查看来自 的标准 Linux，我如何获取这些信息?p>

输出旨在被脚本解析.

解决方案

我建议类似:find .-regex '.*.bak' -print0 |du --files0-from=- -ch |尾 -1

一些注意事项:

• find 的 -print0 选项和 du 的 --files0-from 选项可避免出现问题文件名中有空格
• 正则表达式匹配整个路径，例如./dir1/subdir2/file.bak，而不仅仅是file.bak，所以如果你修改它，请考虑到这一点
• 我使用 h 标志为 du 生成人类可读"格式，但如果您想解析输出，最好使用 k(总是使用千字节)
• 如果您删除 tail 命令，您将另外看到特定文件和目录的大小

旁注:FileLight 是一个很好的 GUI 工具，用于找出谁占用了您的磁盘空间.它不执行正则表达式，但对于查找阻塞磁盘的大目录或文件非常方便.

So, in many situations I wanted a way to know how much of my disk space is used by what, so I know what to get rid of, convert to another format, store elsewhere (such as data DVDs), move to another partition, etc. In this case I'm looking at a Windows partition from a SliTaz Linux bootable media.

In most cases, what I want is the size of files and folders, and for that I use NCurses-based ncdu:

                

But in this case, I want a way to get the size of all files matching a regex. An example regex for .bak files:

.*.bak$

How do I get that information, considering a standard Linux with core GNU utilities or BusyBox?

Edit: The output is intended to be parseable by a script.

解决方案

I suggest something like: find . -regex '.*.bak' -print0 | du --files0-from=- -ch | tail -1

Some notes:

• The -print0 option for find and --files0-from for du are there to avoid issues with whitespace in file names
• The regular expression is matched against the whole path, e.g. ./dir1/subdir2/file.bak, not just file.bak, so if you modify it, take that into account
• I used h flag for du to produce a "human-readable" format but if you want to parse the output, you may be better off with k (always use kilobytes)
• If you remove the tail command, you will additionally see the sizes of particular files and directories

Sidenote: a nice GUI tool for finding out who ate your disk space is FileLight. It doesn't do regexes, but is very handy for finding big directories or files clogging your disk.
