批量更改和替换子目录中的文件扩展名

Question

我想批量修改子目录下的文件。现有文件的扩展名为*.ada.npp。我想将其更改为 *.ada。问题是已经存在具有所需扩展名 *.ada 的文件。这些文件需要替换。

我广泛尝试了 mmv 和 mv 但没有成功（见下文）。

mmv -rd ';*.npp' '\#1'

$ mmv -rd ';*.npp' '\#1'

什么都没做。

Answer 1

这个循环会做你需要的。从您要开始搜索的顶级目录启动它

IFS="
";for F in `find . -name "*.ada.npp"`;do B1=`echo "$F" | sed 's/.ada.npp$//'`;mv -- "$F" "$B1.ada";done

Answer 2

使用find.

find . -name '*.ada.npp' -exec sh -c '
for f; do
  mv -- "$f" "${f%.npp}"
done' _ {} +
