如何复制用grep找到的文件 [英] How to copy files found with grep

问题描述

我正在运行此命令以在树目录中查找包含(借助正则表达式)someStrings"的所有文件.

I am running this command to find all my files that contain (with help of regex)"someStrings" in a tree directory.

grep -lir '^beginString' ./ -exec cp -r {} /home/user/DestinationFolder ; 

它找到了这样的文件:

FOLDER
a.txt
-->SUBFOLDER
  a.txt
---->SUBFOLDER
     a.txt

我想将具有相同架构的所有文件和文件夹复制到目标文件夹，但我不知道该怎么做.复制文件和文件夹很重要，因为找到的几个文件同名，我需要保留它.

I want to copy all files and folder, with the same schema, to the destination folder, but i don't know how to do it. It's important copy files and folder, because several files found has the same name and I need to keep it.

推荐答案

试试这个:

find . -type f -exec grep -q '^beginString' {} ; -exec cp -t /home/user/DestinationFolder {} +

或

grep -lir '^beginString' . | xargs cp -t /home/user/DestinationFolder

但如果你想保持目录结构，你可以:

But if you want to keep directory structure, you could:

grep -lir '^beginString' . | tar -T - -c | tar -xpC /home/user/DestinationFolder

或者如果像我一样，你更喜欢确定你存储的文件类型(只有文件，没有符号链接)，你可以:

or if like myself, you prefer to be sure about kind of file you store (only file, no symlinks), you could:

find . -type f -exec grep -l '^beginString' {} + | tar -T - -c |
    tar -xpC /home/user/DestinationFolder

如果您的文件名可以包含空格和/或特殊字符，请使用空终止字符串来传递grep -l 输出 (arg -Z) 到 tar -T (arg --null -T):

and if your files names could countain spaces and/or special characters, use null terminated strings for passing grep -l output (arg -Z) to tar -T (arg --null -T):

find . -type f -exec grep -lZ '^beginString' {} + | tar --null  -T - -c |
    tar -xpC /home/user/DestinationFolder
