问题描述
我有一大组目录,我试图计算几百个.txt文件的总大小。我试过这个,主要工作: find。 -name * .txt | xargs du -hc
但是最后我没有给我一个总数,我得到了几个。我的猜测是管道一次只能传递很多find的输出行,而du只是在每个批次上运行。有没有办法解决这个问题?
谢谢!

如何使用--files0-from选项到du?您必须相应地生成以null结尾的文件输出:
find。 -name* txt-exec echo -n -e {}\0\; | du -hc --files0-from = -
在我的系统上正常工作。
I have a large set of directories for which I'm trying to calculate the sum total size of several hundred .txt files. I tried this, which mostly works:
find . -name *.txt | xargs du -hc
But instead of giving me one total at the end, I get several. My guess is that the pipe will only pass on so many lines of find's output at a time, and du just operates on each batch as it comes. Is there a way around this?
Thanks!Alex
How about using the --files0-from option to du? You'd have to generate the null-terminated file output appropriately:
find . -name "*txt" -exec echo -n -e {}"\0" \; | du -hc --files0-from=-
works correctly on my system.
这篇关于为什么“查找”。 -name * .txt | xargs du -hc“给多个总数?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
