Why is the line in the bat file not being executed?

Question

cmd/bat

I found a command that works with a bang in the command line on behalf of the administrator:

for /F "tokens=*" %1 in ('wevtutil.exe el') DO wevtutil.exe cl "%1"

This miracle line cleans all (well, almost) Windows logs.
But if you put it in a cmd or bat file and run it as administrator, it does not work.
The window closes immediately.

Answer 1

1. replace %1 with %a, i.e. number to letter. In batch files, digital variables are command line parameters passed to the batch file. You must use literal variables in loops.
2. In the bat file, use 2 % signs before the variable: %%a

Answer 2

when you run as administrator - the working folder for the bat file is "C:\Windows\System32", so there is no wevtutil.exe there.
Add cd /d "%~dp0" to the beginning of the batch file and you will be happy (if there is wevtutil.exe next to the batch file)
