What is the subroutine for testing a name for wildcards?

@echo off & setlocal enableextensions

:IsWildSub
setlocal enableextensions
echo %1|find "*">nul
if %errorlevel% EQU 0 (endlocal & set %2=yes& goto :EOF)
echo %1|find "?">nul
if %errorlevel% EQU 0 (endlocal & set %2=yes& goto :EOF)
endlocal & set %2=no& goto :EOF
The output
D:\TEST>cmdfaq
"My * file" contains wildcards
No wildcards in "My file"
All the best, Timo

What about commands which resolve folder names to contained files?
But maybe this indirect wildcard is a different question for
(un-)ambiguity.

Hello Timo,
IMHO the overhead of a subroutine isn't justified:-
echo:%1 | findstr "* ?" >nul && echo/Wildcards found.

Ritchie, undo for mail

Thank you! It actually is about any string containing either * or ?.
Still, perhaps I had better rephrease this as
"What is the subroutine for testing a filename for wildcards?"
even if that is not quite accurate, either.

It is a good point. If one is striving for efficiency as the primary
goal, you are quite right. However, for a hopefully pedagogical FAQ,
I am not. I am trying to cover the different techniques of CMD
command line script programming. One of the important properties
introduced with it is the usage of subroutines.

Change it to this then:
:IsWildSub
echo:%* | findstr "* ?" >nul & goto :EOF

Thank you. But that's not quite it. It should return the status.
Else it is just the same thing in a slightly different part of the
script.

The status is 'returned' by way of setting the errorlevel.
set "var=My * file.txt"
call :IsWildSub %var% && (echo/Contains wildcards)
goto :EOF
:IsWildSub
echo:%* | findstr "* ?" >nul & goto :EOF
