renaming files in cmd using wildcards
提问by kru96
I'm writing a BAT file for renaming some files.
My files are *.jpgwhere * is the file name and I want them to be *-thumb.jpg.

Something like:
就像是：
for %%f in (*.jpg) do rename "%%f" "%%~nf-thumb.jpg"

Actually the RENAME command alone can solve the problem, as long as there is only one .in the name. Simply use many ?instead of a single *.
其实只用RENAME命令就可以解决问题，只要.名字中只有一个即可。只需使用 many?而不是单个*.
REN *.jpg ????????????????????-thumb.*
Just make sure the number of ?is at least as long as the longest file name that will be renamed.
只需确保数量?至少与要重命名的最长文件名一样长。
You can ensure that names with multiple .are not accidentally named by using many ?in the source mask as well. The following will rename "abc.jpg" to "abc-thumb.jpg", but will leave "abc.xyz.jpg" alone.
您还可以.通过?在源掩码中使用 many来确保不会意外命名具有多个的名称。以下内容将“abc.jpg”重命名为“abc-thumb.jpg”，但不会单独留下“abc.xyz.jpg”。
REN ????????????????????.jpg ????????????????????-thumb.*
You can rename a file with two dots like "abc.xyz.jpg" using the following.
您可以使用以下命令重命名带有两个点的文件，例如“abc.xyz.jpg”。
REN ????????????.????????????.jpg ????????????.????????????-thumb.*
The pattern can be extended for any number of dots in the name.
该模式可以扩展为名称中任意数量的点。
