用'查找'选择的文件组的总大小 [英] total size of group of files selected with 'find'

问题描述

例如，我有一个比我预期的更快的大文件系统。所以我寻找什么被添加：

pre $ find $ / rapid_shrinking_drive / -type f -mtime -1 -ls |减去

我发现很多东西。数以千计的六七类文件。

$ p $ find $ / rapid_shrinking_drive / -name* offender1 *-mtime -1 - ls | wc -l

但是我真正喜欢的是能够获得磁盘上的总大小
$ b

  find / rapidly_shrinking_drive / -name* offender1 *-mtime -1 |如果有人有一个，我打开Perl的一行，但我我不打算使用任何涉及多行脚本或File :: Find的解决方案。     命令< a href =http://linux.die.net/man/1/du =noreferrer>  du  告诉你磁盘使用情况。 
 $ b 
  find quickly_shrinking_drive / -nameoffender1-mtime -1 -print0 | du --files0-from =  -  -hc | tail -n1 
  
 
 
 <先前我写过 du -hs ，但是在我的机器上，似乎忽略 find 的输入，而是总结了cwd的大小。）
 
For instance, I have a large filesystem that is filling up faster than I expected. So I look for what's being added:
find /rapidly_shrinking_drive/ -type f -mtime -1 -ls | less
And I find, well, lots of stuff. Thousands of files of six-seven types. I can single out a type and count them:
find /rapidly_shrinking_drive/ -name "*offender1*" -mtime -1 -ls | wc -l
but what I'd really like is to be able to get the total size on disk of these files:
find /rapidly_shrinking_drive/ -name "*offender1*" -mtime -1 | howmuchspace
I'm open to a Perl one-liner for this, if someone's got one, but I'm not going to use any solution that involves a multi-line script, or File::Find.
解决方案
The command du tells you about disk usage. Example usage for your specific case:
find rapidly_shrinking_drive/ -name "offender1" -mtime -1 -print0 | du --files0-from=- -hc | tail -n1
(Previously I wrote du -hs, but on my machine that appears to disregard find's input and instead summarises the size of the cwd.)
