Script for cleaning data on a regular basis

[a bv]

I found some scripts but i have to edit them to give the true table
name to drop. Its format is

name1_name2_yearmonth    which year and month here we are talking
about is the year and date before the current day . So how can i give
this variable to the script?

Regards
