Linux - 如何将位于多个子目录中的相同扩展名的文件直接复制到一个子目录中？

Question

I have a folder which has many subdirectories, each with a *.nr file in them. There are 1000 subdirectories, each containing at least one *.nr file. Is there a quick way to copy all those *.nr files into a single directory?

I can write a quick python script to iterate through the files, but this seems like overkill if there is a quick command line based way to do it.

I've been googling, but I'm not sure what exact terms I should be googling.

Thanks!

Answer 1

就像是

find /path/to/src -name "*.nr" -exec cp \{\} /path/to/dest \;

Answer 2

If you're on a system with GNU cp , this will do it faster:

find /path/to/src -name "*.nr" -print0 | xargs -0 cp -t /path/to/dest

Copying all .c files under my src dir:

time find ~/src -name "*.c" -exec cp \{\} ~/src/Cfound/ \;
. . .
real    0m1.838s
user    0m9.530s
sys     0m1.110s

time find . -name "*.c" -print0 | xargs -0 cp -t ./Cfound/
. . .
real    0m0.057s
user    0m0.010s
sys     0m0.060s

Answer 3

bash中最简单的方法：

for F in */*.nr; do cp $F otherdir/ ; done
