如何将文件名更改为数字的文件复制到同一目录中

Question

I would like to copy mutiple files using patterns for a new file name.

For example:

./happycat1_sm.png
./happydog1.png
./happyrat1.png

How do I copy these files into the following filename automatically using bash-script?

./happycat2_sm.png
./happydog2.png
./happyrat2.png

Many thanks

Answer 1

for file in $(find . -maxdepth 1 -type f); do cp "${file}" $(echo "${file}" | sed 's/1/2/'); done

这将复制当前目录中的所有文件，将1替换为2。由于它用于特定目的并且不是很可重用，因此它并不是真正有用，但也许正是您所需要的。

Answer 2

The below will copy files and rename the files in destination directory by replacing '1' with '2'

#!/bin/sh

for file in src/*
do
    cp "$file" dest/
    mv -- "dest/$file" "dest/${file/1/2}"
done
