Rclone + windows, which is best script language? .bat? powershell?


I am sticked to windows + rclone,
I wanna write script that say ask for current time stamp,
and then do rclone copy source target with logfile–timestamp,
among other functions.

I think for the coming 10 years I will stick with windows + rclone,
what will be the best script language for this?
.bat batch?

WHATIF if 10years later I want
rclone + windows + linux?
for this which script language will be better?

thank you.

Would be nice if someone can show some rclone scripts on windows and/or linux.
