使用Batch变量重命名文件 [英] Renaming file with Batch variable

问题描述

我有以下代码:

set DATE=%date% 
echo %DATE% 
set DAY=%DATE:~0,2% 
echo %DAY% 
rename file09.txt file%DAY%09.txt
pause

应该重命名一个文本文件，并将该月中的某天放在文件名中.但是，我在rename命令上遇到语法错误.

It is supposed to rename a text file and put the day of the month in the file name. I am however getting a syntax error on the rename command.

我认为问题出在将变量插入文件名中.任何帮助，将不胜感激. echo仅在程序中供我自己参考.

I think the problem is in inserting the variable into the file name. Any help would be appreciated. The echos are just in the program for my own reference.

推荐答案

如前所述-您粘贴的代码在许多行上都有尾随空格，而空格通常很重要.之所以发布此消息，是因为您已重用了系统DATE变量名，这会引起问题，并向您显示引号通常很有用-长文件名需要使用引号.

As has already been stated - your code as pasted had trailing spaces on many lines and the spaces often matter. I posted this because you had reused the system DATE variable name and that causes issues, and to show you that quotes are often helpful - and needed with long filenames.

set "D=%date%"
echo "%D%"
set "DAY=%D:~0,2%"
echo "%DAY%"
rename "file09.txt" "file%DAY%09.txt"
pause
