[文件操作] 批处理怎样遍历并且删除每个用户文件夹下指定格式文件？

ppappa2001

大家好, 小弟学艺不精.. 有如下需求请大侠帮忙.

需求: 在多用户登录的电脑上, 能删除Win7每个用户文件夹下的缓存文件.  以下是我写的代码, 遇到错误, 请大家指正. 谢谢

#1, 脚本需要遍历 C:\users\   
#2, 判断 C:\Users\xxxx\AppData\Local\Microsoft\outlook\ 文件夹下是否存在 outlook.ost 和 *.pst文件.
#3, 如果存在, 并且删除掉.
#4, 再循环 判断和删除下一个用户文件夹的 邮件缓存文件.
#5, 对删除成功的文件记录到文本日志文件.

@echo off

::枚举用户文件夹名字写入list.txt
dir /ad /b c:\users > list.txt

Set RootFolder = C:\Users\
Set SubFolder = \AppData\Local\Microsoft\Outlook\

echo %RootFolder%
echo %SubFolder%

::读取list.txt 连接成绝对路径
for /f %%i in (list.txt) do (
echo %RootFolder% & %%i &  %SubFolder%

:: 连接成为绝对路径, (路径显示不正确.)
Set MyPath = %RootFolder% & %%i & %SubFolder%

::判断路径是否存在, 如果存在就做删除操作.
if exist %MyPth% (del /s /f %MyPath%outlook.ost)

)
PAUSE
复制代码

运行结果:

ECHO is off.
ECHO is off.
The syntax of the command is incorrect.

find

    谢谢Find..   但是执行结果还是不对.  可能是路径连接的地方有问题. 我把变量 这样写echo %RootFolder%&%%i&%SubFolder%, 还是不对... 请指教

list.txt 文件内容是:
All Users
Default
Default User
admin
Public

命令行执行结果如下:

\AppData\Local\Microsoft\Outlook\

连接的时候不需要使用&符号

ppappa2001

去掉过后, 路径对了..


但是在判断文件是否存在时候,  删除动作没执行. 也没报错..

C:\Users\
\AppData\Local\Microsoft\Outlook\
C:\Users\All\AppData\Local\Microsoft\Outlook\
C:\Users\Default\AppData\Local\Microsoft\Outlook\
C:\Users\Default\AppData\Local\Microsoft\Outlook\
C:\Users\admin\AppData\Local\Microsoft\Outlook\
C:\Users\Public\AppData\Local\Microsoft\Outlook\

修改以后的代码如下:

@echo off

::枚举用户文件夹名字写入list.txt
dir /ad /b c:\users > list.txt

Set RootFolder=C:\Users\
Set SubFolder=\AppData\Local\Microsoft\Outlook\

echo %RootFolder%
echo %SubFolder%

::读取list.txt 连接成绝对路径
for /f %%i in (list.txt) do (
echo %RootFolder%%%i%SubFolder%

:: 连接成为绝对路径, (路径显示不正确.)
Set MyPath = %RootFolder%%%i%SubFolder%

::判断路径是否存在, 如果存在就做删除操作.
if exist %MyPth% (del /s /f %MyPath%outlook.ost)

)



PAUSE

find

重新改过了.

    @echo off

::枚举用户文件夹名字写入list.txt
dir /ad /b c:\users > list.txt

Set RootFolder=C:\Users\
Set SubFolder=\AppData\Local\Microsoft\Outlook\

echo %RootFolder%
echo %SubFolder%

::读取list.txt 连接成绝对路径
for /f %%i in (list.txt) do (
echo %RootFolder%%%i%SubFolder%

:: 连接成为绝对路径, (路径正确如: C:\Users\Default\AppData\Local\Microsoft\Outlook\)
Set MyPath=%RootFolder%%%i%SubFolder%

echo %MyPath%outlook.ost
echo ..
::判断路径是否存在, 如果存在就做删除操作.
if exist %MyPath%outlook.ost (del /s /f %MyPath%outlook.ost)
复制代码

结果:

C:\Users\
\AppData\Local\Microsoft\Outlook\
C:\Users\All\AppData\Local\Microsoft\Outlook\
C:\Users\Public\AppData\Local\Microsoft\Outlook\outlook.ost
..
C:\Users\Default\AppData\Local\Microsoft\Outlook\
C:\Users\Public\AppData\Local\Microsoft\Outlook\outlook.ost
..
C:\Users\Default\AppData\Local\Microsoft\Outlook\
C:\Users\Public\AppData\Local\Microsoft\Outlook\outlook.ost
..
C:\Users\admin\AppData\Local\Microsoft\Outlook\
C:\Users\Public\AppData\Local\Microsoft\Outlook\outlook.ost
..
C:\Users\Public\AppData\Local\Microsoft\Outlook\
C:\Users\Public\AppData\Local\Microsoft\Outlook\outlook.ost

文件还是没删掉....

而且很纳闷, 为啥第19行输出的 都变成了 Public

C:\Users\Public\AppData\Local\Microsoft\Outlook\outlook.ost

改了还是一样的结果喃?

find

@echo off
set RootFolder=C:\Users
set SubFolder=AppData\Local\Microsoft\Outlook
for /f "delims=" %%i in ('dir /ad /b C:\users') do (
    echo %RootFolder%\%%i\%SubFolder%\outlook.ost
    if exist "%RootFolder%\%%i\%SubFolder%\outlook.ost" (
        del /f /q "%RootFolder%\%%i\%SubFolder%\outlook.ost"
    )
)
复制代码

完美   多谢find

回复 12# find

我把文件名字改成了通配符格式.

@echo off

set RootFolder=C:\Users

set SubFolder=AppData\Local\Microsoft\Outlook

for /f "delims=" %%i in ('dir /ad /b C:\users') do (
REM  echo %RootFolder%\%%i\%SubFolder%\*.ost

    if exist "%RootFolder%\%%i\%SubFolder%\*.ost" (
        dir /b %RootFolder%\%%i\%SubFolder%\*.ost>>Delete.log
        del /f /q "%RootFolder%\%%i\%SubFolder%\*.ost"

    )
)
复制代码

能不能在第12行的 删除操作之前, 把删除的文件路径写入日志文件喃?

我增加了删除之前枚举文件的命令. 如果删除成功, 那么删掉的文件就是被枚举的文件. 但是如果进程被占用, 那么文件并没有被删除, 而文件名还是被写入日志, 就不符合实际..  有啥办法只把删掉的文件写入日志..??

你的思路本来就有问题。
