How to add a variable instead of a number in a batch file?

Question

cmd/bat

Here are my pathetic attempts

for /L %%i IN (1,1,10000000000) do call :doschtasks %i
goto :EOF
:doschtasks
set FN=%i
schtasks /delete /tn "Opera GX scheduled Autoupdate %FN%" /f
pause

The task is to remove the task "Opera GX scheduled Autoupdate 1615341492"
the last numbers always change,

you need to either batch brute
from 1 to 10kkk
or come up with something cooler

ideas?

Answer 1

The following lines have been corrected:

for /L %%i IN (1,1,10000000000) do call :doschtasks %%i

set FN=%1

although all this can be done in one line without CALL.
But, in order not to sort through all the numbers, you can try to process the output schtasks /queryto get the names of the current jobs:

for /f "usebackq delims=" %%L in (`schtasks /query /fo csv /nh^|find "Opera GX scheduled Autoupdate "`) do  call :sub %%L
exit /b

:sub
schtasks /delete /tn %1 /f
