随机选择文件、重命名、移动到新目录

随机选择文件、重命名、移动到新目录

我们有一个目录,里面有 40 多个文件,这些文件有不同的文件名。它们都以相同的文件名结构开始,但末尾附加了一个日期。

例子:

FILE.txt.01012013
FILE.txt.01022013
FILE.txt.01032013

我需要创建一个批处理文件来执行一些复杂的事情和一些不太复杂的事情:

  1. 仅选择一个文件。
  2. 将该文件重命名为其他名称。(例如:TEST.txt)注意:重命名文件的名称始终为 TEST.txt)
  3. 将重命名的文件从当前目录移动到新目录。
  4. 15 分钟后...再次从步骤 1 开始。(注意:这需要持续运行,直到原始目录中没有剩余文件。)

我尝试过的方法:我对批处理文件的技能水平非常基础,因此我一直在尝试在网上搜索建议。我可以找到重命名文件的代码(但您必须说明原始文件名)。我可以找到使用文件名中的 * 来查找文件的代码,但我认为这会选择目录中的所有文件。我需要它一次对一个文件进行一次,每 15 分钟一次。一旦文件被重命名并移动到新目录...就会有一个文件观察程序进程获取该文件(在此示例中为 TEST.txt)并提取数据。一旦数据被提取,文件就会被删除。这意味着当下一个文件被重命名为 TEST.txt 并移动到目录时,没有任何理由覆盖前一个文件。

答案1

这看起来像是您想要的,但是您需要填补空白。

set count=0
for /f %%i in (file_path\*.*) do set /a count+=1
set test=%count%
:loop
if %test% neq %count% timeout /nobreak 900 >nul
set /a num=%random% %% %count% + 1
set /a count-=1
if %count% leq 0 goto end
for /f "skip=%num%" %%i in (file_path\*.*) do (
    ren %%i TEST.txt
    move TEST.txt file_path\
    goto loop
)
:end

它能做什么:

  1. 找出文件夹中有多少个文件(您需要更改)。
  2. 生成一个随机数,其最大值为文件夹中的文件数量。
  3. 从最大数字中减去一个,以备下次使用。
  4. 跳过随机数量的文件(由随机数指定)并选择下一个。
  5. 将文件重命名为 TEXT.txt 并将其移动到 file_path\(您需要更改)。
  6. 等待 15 分钟(900 秒)。

希望有所帮助。

注意,您需要将 **file_path** 更改为适当的文件。

试试这个,它可以完成你要求的所有事情:

@echo off&setlocal enabledelayedexpansion
set "startfolder=folder1"
set "targetfolder=folder2"

cd /d "%startfolder%"
:randomstart
set /a filecnt=0
for %%i in (*) do set /a filecnt+=1
if %filecnt% equ 0 echo(no file found in %Startfolder%&goto:eof
set /a rd=(%random%%%%filecnt%)+1
set /a cnt=0
for %%i in (*) do set /a cnt+=1&if "!cnt!" equ "%rd%" set "randomfile=%%~i"
echo "%randomfile%"
move "%randomfile%" "%targetfolder%\test.txt"
ping -n 900 localhost >nul
goto:randomstart

答案3

这是一个处理文件的简单批处理脚本:

@echo off

rem     set your file-match pattern here. Could be *.* for all files, or whatever you wish.
set "zzmatchpattern=FILE.txt.*"

rem     set filename for renamed files
set "zzfinalname=TEST.txt"

rem     set source folder here
set "zzsourcepath=C:\source\"

rem     set destination folder here
set "zzdestpath=C:\dest\"

rem     set your loop delay here
set "zzdelayminutes=15"

rem     **********************************
rem     might be good to add some error checking here
rem     **********************************


:start
rem:start
set /a zzdelayseconds=zzdelayminutes*60


:restart
rem:restart

for %%f in ("%zzsourcepath%%zzmatchpattern%") do call :work "%%~f"

timeout /t %zzdelayseconds%
goto :restart


:work
rem:work

set "zz_w1=%~1"
echo.
echo Renaming file "%zz_w1%" to "%zzfinalname%"
ren "%zz_w1%" "%zzfinalname%">nul 2>&1

echo Moving file: "%zzsourcepath%%zzfinalname%" to "%zzdestpath%"
move "%zzsourcepath%%zzfinalname%" "%zzdestpath%">nul 2>&1

timeout /t %zzdelayseconds%

rem     Go get next file, if any.
goto :EOF



如果您想要更完整的解决方案,下面的批处理脚本包括:

  • 对输入值进行相当完整的验证(错误检查)。
  • 通过简单的修改,就可以安全地从命令行输入值。
  • 开始时,检查现有目标文件是否存在并等待外部进程删除文件。
  • 检查并报告失败的重命名和移动操作。
  • 退出/失败后恢复进程文件重命名但未移动。
  • 允许(可选)提示延迟(Choice.exe)允许“立即继续”和优雅“退出”。
