cmd将文本插入文件名的中间

问题描述

我将文件从一个目录移动到新创建的目录。当前脚本将id变量插入到所有文件名的文件名的开头。
我想在所有文件名中插入模型名变量之后的id变量。

I am moving files from one directory to a newly created directory. Currently the script inserts the id variable to the start of the file name for all the file names.I would like to insert the id variable after model name variable in all the file names. How do I do that?

我在cmd文件中有以下代码。

I have the following code in my cmd file.

@echo off

rem set 12d variables
set modelname=dr network_
set id=10yr_

mkdir "%modelname%"

rem move to new dir created
move "%modelname%*.rpt" "%modelname%"

rem change working directory
cd "%modelname%"

rem for each file rename it and add the new prefix %id% to the file name
for %%f in ("%modelname%*.rpt") do (

    rename "%%f" "%id%%%f"
)

推荐答案

一些小的改动，应该让你去。

A few small alterations, should get you going.

@echo off
SETLOCAL ENABLEDELAYEDEXPANSION

rem set 12d variables
set modelname=dr network_
set id=10yr_

mkdir "%modelname%"

rem move to new dir created
move "%modelname%*.rpt" "%modelname%"

rem change working directory
cd "%modelname%"

rem Work out how long the modelname is
echo %modelname%>strlen.txt
for %%a in (strlen.txt) do set /a modelNameLength=%%~za - 2
del strlen.txt

rem for each file rename it and add the new text %id% to the middle of the file name
for %%f in ("%modelname%*.rpt") do (
    set newfilename=%%f
    set newfilename=!newfilename:~0,%modelNameLength%!%id%!newfilename:~%modelNameLength%!
    ren "%%f" "!newfilename!"
)
