从dir和所有子目录获取所有文件,除了一个子目录



我目前在Windows批处理文件中使用这一行:

@ REM List all *.f in current dir and all its subdirs
dir *.f /B /S > temp1.txt

不幸的是,其中一个子目录(我们将其命名为pest)有一个非常大的子树,这使得该过程非常缓慢。由于pest子目录实际上对这个特定的任务不重要(它不应该包含任何相关的文件),我想从搜索中排除它。

所以,我想在当前目录和所有子目录中搜索,而不是在当前目录和所有子目录中搜索,除了pest

你能提出一个简单的方法吗?

如果pest是根目录(即当前目录.)的直接子目录,则可以执行以下操作:

rem // Enumerate immediate child files in the root, output them:
> "temp1.txt" (for %%F in (".*.f") do @echo %%~fF)
rem // Enumerate immediate subdirectories of the root:
>>"temp1.txt" (
    for /D %%D in (".*.*") do @(
        rem // Skip the rest if current subdirectory is the one to exclude:
        if /I not "%%~nxD"=="pest" (
            rem // Output all files found in the current subdirectory recursively:
            pushd "%%~D"
            for /R %%E in ("*.f") do @echo %%~E
            popd
        )
    )
)

只返回文件,不返回目录;如果您也希望包含这样的内容,请尝试以下代码:

rem // Output the path to the root directory itself:
> "temp1.txt" (for /D %%D in (".") do @echo %%~fD)
rem // Enumerate immediate child files in the root, output them:
>>"temp1.txt" (for %%F in (".*.f") do @echo %%~fF)
rem // Enumerate immediate subdirectories of the root:
>>"temp1.txt" (
    for /D %%D in (".*.*") do @(
        rem // Skip the rest if current subdirectory is the one to exclude:
        if /I not "%%~nxD"=="pest" (
            rem // Output the current subdirectory:
            echo %%~fD
            rem // Output all files found in the current subdirectory recursively:
            for /F "eol=| delims=" %%E in ('dir /B /S "%%~D*.f"') do @echo %%E
        )
    )
)

如果pest子目录可以在树中的任何位置,您可以使用这种方法:

@echo off
rem /* Call subroutine with the root directory (the current one), the file pattern
rem    and the name of the directory to exclude as arguments: */
> "temp1.txt" call :SUB "." "*.f" "pest"
exit /B
:SUB  val_dir_path  val_file_pattern  val_dir_exclude
rem // Output directory (optionally):
echo %~f1
rem // Enumerate immediate child files and output them:
for %%F in ("%~1%~2") do echo %%~fF
rem // Enumerate immediate subdirectories:
for /D %%D in ("%~1*.*") do (
    rem // Skip the rest if current subdirectory is the one to exclude:
    if /I not "%%~nxD"=="%~3" (
        rem /* Recursively call subroutine with the current subdirectory, the file pattern
        rem    and the name of the directory to exclude as arguments: */
        call :SUB "%%~D" "%~2" "%~3"
    )
)

要避免也输出子目录,只需删除命令行echo %~f1

由于此方法具有递归子例程调用的特性,因此在没有pest子目录的情况下,性能明显比使用简单的dir /S命令差。

您可以使用RoboCopy中的目录排除功能:

@Echo Off
(Set SrcDir=C:UsersParkerDocuments)
(Set SrcMsk=*.f)
(Set ToExcl=pest)
(Set OutPut=temp1.txt)
>"%OutPut%" (For /F "Tokens=*" %%A In ('RoboCopy "%SrcDir%" NULL %SrcMsk%^
 /L /S /FP /NDL /NS /NC /NJH /NJS /XD "%ToExcl%"') Do Echo=%%A)

根据需要对括号内的四行进行相应的修改
