从文本文件中指定的目录中复制几个文件（Linux）

Question

I have a directory called images and it contains many images. For example:

images/
    imag001.png
    imag002.png
    imag003.png
    imag004.png

And I have a text file that has the files that I want to copy somewhere else. Say the test.txt file has

img001.png
img003.png

How do I copy the files specified in test.txt from the images folder to some other place?

Answer 1

尝试在您的images目录下使用此一线：

awk '{print "cp "$0" /target/path"}' test.txt|sh

Answer 2

I think in the bash shell you can do:

for image in $(cat copylist.txt); do
    cp $image destination
done

Answer 3

You can write:

while IFS= read -r image_filename ; do
    cp images/"$image_filename" some_other_place/
done < test.txt

Answer 4

There are probably many solutions to this problem. I would do it by using xargs:

cd images/
cat path/to/test.txt | xargs -I FILES cp FILES path/to/dest/

Answer 5

 cat copylist.txt  | xargs -n1 -I %  echo cp   % destination/.
 # remove echo after testing
