可用gawk（ http://bcn.bathome.net/tool/5.1.0/gawk.exe ）来查找：

@rem 查找第1个有效链接
@echo off
rem 保存为ANSI编码格式
set "out="
FOR /L %%A IN (20230801,1,20230831) DO (
	for /f %%B in ('wget --spider "https://www.win-rar.com/fileadmin/winrar-versions/sc/sc%%A/rrlb/winrar-x64-623sc.exe" 2^>^&1^|gawk "NR==2{Fn=$NF}/Remote file exists\./{print Fn}"') do set "out=%%B"
	if defined out goto exit_label
)
:exit_label
if defined out (
	echo;第1个有效链接：%out%
)	else echo;未找到有效链接
