批处理脚本，用于使用目录的结果
我正在尝试编写一个小批处理脚本，该脚本将从目录中删除文件旧文件。 第一个参数是脚本要查看的目录，第二个参数是要保留的文件数。
rem @ECHO OFF
rem %1 is the path in which to look for the files
rem %2 is the number of recent files to preserve
if [%1] EQU [] (
echo ERROR: Missing Required Paramater directory path.
goto :eof
)
if [%2] EQU [] (
echo ERROR: Missing Required Paramater, number of files to preserve
goto :eof
)
if %2 LSS 0 (
echo ERROR: Number of files to preserve provided was negative
goto :eof
)
set FolderPath=%1
set SafeNumber=%2
cd %FolderPath%
for /f %%f in ('dir /O-D /A-D /B') do call :delete %%f
goto :eof
:delete
if %SafeNumber% LEQ 0 (
del %1
) else (
set /a SafeNumber-=1
)
goto :eof
:eof
本质上，我这里有一个目录，它输出按从最新到最旧的顺序排列的文件名列表。 根据 SafeNumber 的不同，它将跳过前几个文件，然后在 SafeNumber <= 0 后继续删除。
我现在遇到的问题是，如果文件名是“Test File.txt”（如包含空格。“Test”作为 %1 传递到删除中，而不是“Test File.txt”。
有关如何使我的脚本工作的任何想法，或者也许有人有更好的书面解决方案？
I'm trying to write a small batch script that will delete files old files from a directory.
The first parameter is the directory for the script to look into, and the second is the number of files to preserve.
rem @ECHO OFF
rem %1 is the path in which to look for the files
rem %2 is the number of recent files to preserve
if [%1] EQU [] (
echo ERROR: Missing Required Paramater directory path.
goto :eof
)
if [%2] EQU [] (
echo ERROR: Missing Required Paramater, number of files to preserve
goto :eof
)
if %2 LSS 0 (
echo ERROR: Number of files to preserve provided was negative
goto :eof
)
set FolderPath=%1
set SafeNumber=%2
cd %FolderPath%
for /f %%f in ('dir /O-D /A-D /B') do call :delete %%f
goto :eof
:delete
if %SafeNumber% LEQ 0 (
del %1
) else (
set /a SafeNumber-=1
)
goto :eof
:eof
Essentially what I have here is a dir that outputs a list of filenames ordered from newest to oldest. Depending on what SafeNumber is, it will skip the first few files and then procede with deletion once SafeNumber <= 0.
The problem I'm having right now, is if the filename is "Test File.txt" (as in contains a space. "Test" is passed into the delete as %1, rather then "Test File.txt".
Any ideas on how to get my script working, or perhaps someone has a better written solution?

处理文件名等中的空格。 您需要引用文件名和路径“%1”等......也许这是您唯一的问题。
To handle whitespace in filenames,etc. You'll want to quote for filenames and paths "%1" etc.... Maybe that is your only problem.
您必须将 find 命令与 -newer 一起使用，然后使用 -exec rm 。 例如，要删除比 file.txt 新的所有文件，请执行以下操作：
your going to have to use the find command with -newer and then -exec rm. For example to delete all file newer than file.txt do:
很久以前，我编写了一个简单的 Java prog，它应该从控制台启动，即从批处理文件启动。 prog 从指定目录中删除旧文件。 看看这里，我实际上不知道不记得它到底是如何工作的，但我建议首先在测试文件夹上使用它。 它应该用于Windows，至少我在那里使用它。
我现在切换到 Mac，使用每次启动时启动的以下 Automator 脚本来完成这项工作：
Long time ago, I wrote a simple Java prog that is supposed to be launched from the console, i.e. from a batch file. The prog deletes the old files from a specified directory. Check it out here, I actually don't remember how exactly it works, but I would suggest using it first on a test-folder. It is supposed to be used for Windows, at least there it is where I used it.
I now switched to a Mac, where I'm using the following Automator script I launch on each boot for doing that job:
更改您的 for 循环，并取消删除功能。
我对 for 循环有一种不健康的热爱......
Change your for loop, and do away with your delete function.
I have an unhealthy love of for loops...
您是否尝试过在输入或脚本中的文件名两边加上引号？ 我的意思是脚本的 %f 或 %1 周围。
Have you tried putting quotation marks around the file name in your input, or in your script? I mean around the %f or the %1, for the script.
