cmd 在文件名中间插入文本

Question

我正在将文件从一个目录移动到一个新创建的目录。目前，脚本将 id 变量插入到所有文件名的文件名开头。我想在所有文件名中的模型名称变量之后插入 id 变量。我该怎么做？

我的 cmd 文件中有以下代码。

@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"
)

Answer 1

一些小改动，应该可以让你继续。

@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!"
)

tfizhardinge, Scott C 使用 cmd 提供了正确答案。

这里有一个 Powershell 选项，我已经尝试匹配你的 cmd 代码，所以你可以看到发生了什么。

# Rename using replace to insert text in the middle of the name

# Set directory where the files you want to rename reside
# This will allow you to run the script from outside the source directory
Set-Variable -Name sourcedir -Value "c:\test"

# Set folder and rename variables
Set-Variable -Name modelname -Value "dr network_"
Set-Variable -Name id        -Value "10yr_"

# Set new filename which is modelname string + id variable
Set-Variable -Name newmodelname -Value $modelname$id

# Check if folder exisits, if not create
if(!(Test-Path -Path $sourcedir$modelname )){
    # rem make directoy with modelname variable
    New-Item -ItemType directory -Path $sourcedir$modelname
}

# Move the rpt files to new dir created
Move-Item -Path $sourcedir\*.rpt -Destination $sourcedir$modelname

# Using GetChildItem (i.e. Dir in dos) command with the pipe, will send a list of files to the Rename-Item command
# The Rename-Item command is replacing the modelname string with new modelname string defined at the start
Get-ChildItem -Path $sourcedir$modelname | Rename-Item -NewName { $_.name -replace $modelname, $newmodelname }

# You can remove the stuff below this line -----
# Pause here so you can check the result.

# List renamed files in their new directory
Get-ChildItem -Path $sourcedir$modelname
# rem Pause
Write-Host "Press any key"
$pause = $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")

# rem End ------
