如何在bash中使用通配符重命名文件? [英] How to rename files using wildcard in bash?

问题描述

我试图将某些文件重命名为另一个扩展名:

I was trying to rename some files to another extension:

# mv  *.sqlite3_done *.sqlite3

但出现错误:

mv: target '*.sqlite3' is not a directory

为什么?

推荐答案

通配符扩展导致将多个名称传递给命令.Shell认为您正在尝试将多个文件移动到 *.sqlite3 目录.

The wildcard expansion results in multiple names being passed to the command. The shell thinks you are trying to move multiple files to the *.sqlite3 directory.

您需要使用循环:

for nam in *sqlite3_done
do
    newname=${nam%_done}
    mv $nam $newname
done

％_ done 说要从字符串中删除最后一次出现的 _done .

The %_done says to remove the last occurrence of _done from the string.

如果文件名中可能包含空格，则需要引用文件名.

If you may have spaces in your filenames you will want to quote the filenames.
