“找到"与"xargs"和"tar" [英] 'find' with 'xargs' and 'tar'

问题描述

我要执行以下操作:

find . -maxdepth 6 \( -name \*.tar.gz -o -name bediskmodel -o -name src -o -name ciao -o -name heasoft -o -name firefly -o -name starlink -o -name Chandra \) -prune -o -print | tar  cvf somefile.tar --files-from=-

即，排除大量内容，仅查看六个子目录的深度，然后在修剪完成后，将其余部分压缩".

I.e., exclude a whole lot of stuff, only look to six subdirectories depth, and then once pruning is done, 'tar' up the rest.

这并不难.管道(|)之前的位有效100％.如果我排除焦油"，那么我将得到(屏幕上)想要的东西.但是一旦我把管道和焦油包括在内，它就会使所有东西都焦油，包括我刚刚在查找"中排除的所有东西.

It is not hard. The bit before the pipe (|) works 100%. If I exclude the 'tar', then I get what I'm after (to the screen). But once I include the pipe, and the tar, it tars everything, including all the stuff I've just excluded in the 'find'.

我尝试了许多不同的迭代:

I've tried a number of different iterations:

-print0 | xargs -0 tar rvf somefile.tar
-print0 | xargs -0 tar rvf somefile.tar --null --files-from=-
-print0 | tar cvf somefile.tar --null -T -

那么我在做什么错了?我以前已经做过；但是现在它只是给我留白发.

So what am I doing wrong? I've done this before; but now it's just giving me grey hairs.

推荐答案

-print 标志的组合，用于查找，然后在-files-from 'tar'命令对我有用.就我而言，我需要压缩5000多个日志文件，但是仅使用'xargs'只能在生成的文件中提供500个文件.

A combination of the -print flag for find, and then --files-from on the 'tar' command worked for me. In my case I needed to tar up 5000+ log files, but just using 'xargs' only gave me 500 files in the resulting file.

find . -name "*.pdf" -print | tar -czf pdfs.tar.gz --files-from -

当您只想"--files-from-"时，您有"--files-from =-".然后我认为您需要在 cvf 前面的-，如下所示.

You have "--files-from=-", when you just want "--files-from -" and then I think you need a - in front of cvf, like the following.

find . -maxdepth 6 ( -name *.tar.gz -o -name bediskmodel -o -name src -o -name ciao -o -name heasoft -o -name firefly -o -name starlink -o -name Chandra ) -prune -o -print| tar -cvf somefile.tar.gz --files-from -
