JSI Tip 1254. How can I grant a user Full Control of an existing file?

In tip 0557, we granted a user Full Control of all new files and folders that they create in a directory.

To grant a user Full Control on existing files in a folder, use:

JSIFCU UserName FullFolderPath,     where JSIFCU.bat contains:

@echo offif NOT {%2}

{} goto begin:syntax@echo Syntax: JSIFCU UserName Folder [/N]goto end:beginsetlocalset user=%1set folder=%2set folder=%folder:"=%if not exist "%folder%*.*" goto syntaxif /i {%3}

{/N} goto nokset found=Nfor /f "Tokens=*" %%i in ('net user %user%') do call :parse "%%i"if "%found%"

"N" goto syntax:nokfor /f "Tokens=*" %%i in ('dir /b /a-d /s "%folder%"') do call :doit "%%i"endlocalgoto end:doitCACLS %1 /E /C /P %user%:F goto end:parseset str=%1if %str%

"The command completed successfully." set found=Y:end

If you have a directory structure like:

FolderUserName1
FolderUserName2
FolderUserNameN

you can use JSIFCUAll.bat, which calls JSIFCU with the /N switch, to do them all.

JSIFCUAll.bat contains :

@echo offif NOT "%1"

"" goto begin:syntax@echo Syntax: JSIFCUAll TopFolder goto end:beginsetlocalset Folder=%1set folder=%folder:"=%if not exist "%folder%*.*" goto syntaxfor /f "Skip=4 Tokens=*" %%i in ('net users') do call :parse "%%i"endlocalgoto end:parseset str=#%1#set str=%str:#"=%set str=%str:"#=%if "%str%"

"The command completed successfully." goto endset substr=%str:~0,25%#set substr=%substr:  =%set substr=%substr: #=%set substr=%substr:#=%if "%substr%"

"" goto endif exist "%folder%%substr%*.*" call JSIFCU "%substr%" "%folder%%substr%" /Nset substr=%str:~25,25%#set substr=%substr: =%set substr=%substr: #=%set substr=%substr:#=%if "%substr%"

"" goto endif exist "%folder%%substr%*.*" call JSIFCU "%substr%" "%folder%%substr%" /Nset substr=%str:~50,25%#set substr=%substr:  =%set substr=%substr: #=%set substr=%substr:#=%if "%substr%"=="" goto endif exist "%folder%%substr%*.*" call JSIFCU "%substr%" "%folder%%substr%" /N:end

To grant a user Full Control of files that they own in a common folder, see tip 1255.
