将版权信息插入多个文件 [英] Insert copyright message into multiple files

问题描述

如何在每个文件的最顶部插入版权信息?

How would you insert a copyright message at the very top of every file?

推荐答案

#!/bin/bash
for file in *; do
  echo "Copyright" > tempfile;
  cat $file >> tempfile;
  mv tempfile $file;
done

递归解决方案(查找所有子目录中的所有.txt文件):

Recursive solution (finds all .txt files in all subdirectories):

#!/bin/bash
for file in $(find . -type f -name \*.txt); do
  echo "Copyright" > copyright-file.txt;
  echo "" >> copyright-file.txt;
  cat $file >> copyright-file.txt;
  mv copyright-file.txt $file;
done

谨慎使用；如果文件名中存在空格，您可能会出现意外行为.

Use caution; if spaces exist in file names you might get unexpected behaviour.
