Answer:
Copy Code code as follows:
@echo off
REM comparison operator: EQU-equals neq-not equal to LSS-less than leq-less than or equal to GTR-greater than GEQ-greater than or equal to
REM modulus operator:% dos modulus operator (percent% in batch file, not batch command line%)
REM Log folder name initial value
Set filelog=%date:~0,10% to
REM Subsequent date of the variable
