Windows批处理文件:如何在保留隐藏和系统属性的同时使隐藏或系统文件成为只读(或非只读)?

attrib命令用于更改隐藏,系统,只读和存档等文件属性。

问题是您不能更改隐藏或系统文件的只读状态 - 无需另外清除或设置隐藏或系统状态。例如:

C:\somewhere>REM Set up a hidden test file.
C:\somewhere>echo foo > foo.txt
C:\somewhere>attrib +h foo.txt

C:\somewhere>REM Try to make the hidden test file read-only.
C:\somewhere>attrib +r foo.txt
Not resetting hidden file - C:\somewhere\foo.txt

C:\somewhere>REM We can make it read-only if we additionally clear the hidden status...
C:\somewhere>attrib -h +r foo.txt

C:\somewhere>REM (Revert that last change.)
C:\somewhere>attrib +h -r foo.txt

C:\somewhere>REM ...and we can make it read-only if we additionally make it hidden - which it already is.
C:\somewhere>attrib +h +r foo.txt
C:\somewhere>

(我假设系统属性的工作方式与上面相同,但我没有测试过。)

因此attrib将用于此目的 - 但仅当批处理文件知道文件是否已隐藏或系统时,才能包含相应的+h+s以及+r

最好的方法是什么?

将隐藏和系统属性保存在变量中,清除并在需要时重新应用。

用法:

call :setAttr "+r -a" "file"
call :setAttr +r "file"
call :setAttr -r "file"

功能:

:setAttr
    :: Usage:
    ::  call :setAttr "+r -a" "file"
    setlocal

    for /f "delims=" %%a in ('attrib "%~2"') do set "attrs=%%a"
    set "attrs=%attrs:~0,10%"

    set toggle=
    if not "%attrs:H=%"=="%attrs%" set toggle=-h
    if not "%attrs:S=%"=="%attrs%" set toggle=%toggle% -s

    if defined toggle attrib %toggle% "%~2"
    attrib %~1 "%~2"
    if defined toggle attrib %toggle:-=+% "%~2"

    endlocal
    exit /b
