复制包含在不同的文件夹父亲许多文件（名称相同） [英] copy many files (same name) contained in different father folder

问题描述

家伙，您好我有一个关于UNIX命令行的问题。我有很多的文件这样的：

Hi guys I have a question about unix command line. I have many files like these:

/f/f1/file.txt

/f/f2/file.txt

/f/f3/file.txt

and so on...

我想复制所有 file.txt的与文件夹父亲在其他的文件夹摹，如：

/g/f1/file.txt

/g/f2/file.txt

/g/f3/file.txt

我不能复制文件夹˚F的所有内容，因为在每个子文件夹F1，F2，... 我有我不想复制许多其他文件。

I can't copy all content of folder f because in each sub-folder f1, f2, ... I have many other files that I don't want copy.

我怎么可以这样使用命令行？最终使用bash脚本？

How could I do this with the command line? Eventually using a bash script?

感谢您！

推荐答案

手册 CP 显示此选项 -

Manual for cp shows this option -

--parents
              use full source file name under DIRECTORY

所以，如果你是在庆典V4 你可以做这样的事情 -

So if you are on bash v4 you can do something like this -

[jaypal:~/Temp/f] tree
.
├── f1
│   ├── file.txt  # copy this file only with parent directory f1
│   ├── file1.txt
│   └── file2.txt
└── f2
    ├── file.txt  # copy this file only with parent directory f2
    ├── file1.txt
    └── file2.txt

2 directories, 6 files
[jaypal:~/Temp/f] mkdir ../g
[jaypal:~/Temp/f] shopt -s globstar
[jaypal:~/Temp/f] for file in ./**/file.txt; do cp --parents "$file" ../g ; done
[jaypal:~/Temp/f] tree ../g
../g
├── f1
│   └── file.txt
└── f2
    └── file.txt

2 directories, 2 files
