根据序列号重命名匹配的文件 [英] Rename matching files based on a serial number

问题描述

假设我有一堆Mac屏幕截图文件:

Assuming I have a bunch of files that are mac screenshots:

Screen Shot 2018-11-09 at 12.37.37 PM.png
Screen Shot 2018-11-10 at 4.53.02 PM.png
Screen Shot 2018-11-10 at 9.19.19 PM.png

我想用mv将它们标记为:

And I want to use mv to label them to:

Screen_0.png
Screen_1.png
Screen_2.png

我想出的部分命令:

find . -name "Screen*" -exec sh -c 'mv "$1" "Screen_$2"' _ {} ??? \;

如何执行命令以使其可以按数字标记图像?还是我不得不求助于更复杂的文件.

How to implement the command so that it can label image by digits? or do I have to resort to a more complicated file.

推荐答案

我认为不可能以您想要的方式传递序列号xargs.而是使用一个简单的循环:

I don't think it is possible to pass a sequence number xargs in the way you want. Use a simple loop instead:

#!/bin/bash
for file in Screen*.png; do
  [[ -f $file ]] || continue # skip if not a regular file
  mv "$file" "Screen_$((count++)).png"
done
