It works fine, carlos. Ta.

I find this disablex.exe very useful now. But I have a problem: I would like to check if disablex.exe is in the path so I would need something like

Code: Select all

disablex.exe /v

/v version info or something - so running the .exe does not disable the 'X'. If disablex.exe is not in the path I get errorlevel=9009 but I want to run it just for some accounts.

Anyone can change the source and make a new .exe, please (this .exe has 1536 bytes - so as small as possible would be great)?

Thanks.

I think even with some trickery I don't get it that lightweight again. (Antonio might be able using Assembler though.)
However, you can always check if an executable is found in the PATH. Use the ~$path: modifier of FOR variables.

Code: Select all

for %%i in ("whatever.exe") do if "%%~$path:i"=="" echo Not found.

Thanks Steffen!

I don't think there is a need for an assembler code. C would do - even if .exe is bigger in size.

Maybe just adding an IF:

Code: Select all

if parameter1="1" then exit 99

So if I execute

Code: Select all

disableX.exe 1
if "%errorlevel%"=="99" echo DISABLEX found.

Code: Select all

set disablex_exists=0
disableX.exe 1
if "%errorlevel%"=="99" set disablex_exists
if "%username%"=="JOHN" if "%disablex_exists%"=="1" disableX.exe

Something like that - as simple as possible because there is no need to complicate.

Thanks (I don't 'speak' C* and I don't have an option to make an .exe).

there is no need to complicate

But this makes it overly complicated. You can check the existence of the tool and you have to check the user name anyway, so you can just contitionally call the tool. I still don't get the point why the update of the tool is needed.

Nevermind... Pass 1 and you'll get return value 99 as per your request.

FWIW I had to explicitly run the tool in a console. Of course it has no effect in a terminal.

Thanks Steffen.

Of course code could be shortened:

Code: Select all

disableX.exe 1
set errlev=%errorlevel%
if "%errlev%"=="99" if "%username%"=="JOHN" disableX.exe
if "%errlev%"=="99" if "%username%"=="JANE" disableX.exe
if "%errlev%"=="99" if "%username%"=="MARY" disableX.exe
if "%errlev%"=="99" if "%username%"=="JILL"  disableX.exe
if "%errlev%"=="99" if "%username%"=="MIKE" disableX.exe

or

Code: Select all

set user_list="#JOHN#JANE#MARY#JILL#MIKE#"
call set tmp_str=%%user_list:#%username%#=X%%
disableX.exe 1
if "%errorlevel%"=="99" if not "%tmp_str%"=="%user_list%" disableX.exe

Thanks again.

Calling a non-existing tool will make the CMD to throw an error. Regardless if you call it with or without an argument.
So isn't that the same thing? :

Code: Select all

set user_"list=#JOHN#JANE#MARY#JILL#MIKE#"
call set "tmp_str=%%user_list:#%username%#=X%%"
if not "%tmp_str%"=="%user_list%" disableX.exe

If you want to get rid of the error message either check if the tool exists (using the FOR loop I wrote above if you expect the tool in the PATH environment, or using IF EXIST if in a certain directory), or redirect the error message using 2>NUL.

I checked your FOR solution. It is great. And as you mention I can add additional check for the current directory.

The idea with the 2>nul is also great.

Thanks for the help.

You can explicitly add the current work dir to PATH for the running cmd session.

Code: Select all

set "path=.;%path%"

After that, the expansion using ~$path: takes it into account.

Thanks again!

You always have a clever solution (short and efficient).
