#!/bin/bash
## USAGE
## ./remove_plots.sh /PATH/TO/DIRECTORY/ 2021-07-01 30m
## first argument is path, must be end with trailing "/"
## second argument is target date, meaning plots that created after this date WILL NOT BE DELETED, if you specify 2021-07-01, only filename containing 2021-06-30 or before wil be deleted.
## third argument is the interval, adjust yourself according to your plotting speed or how soon you want to trigger next deletion.

SOURCE_DIR=$1
TARGET_DATE=${2:-"2021-07-01"}
INTERVAL=${3:-"30m"}
ARR=()

if [ -n "$1" ]; then
  for entry in "$SOURCE_DIR"*
  do
    FILE_NAME=$(basename "$entry")
    FILE_DATE=${FILE_NAME:9:10}
    [[ $FILE_DATE < $TARGET_DATE ]] && ARR+=($entry)
  done
  echo "${#ARR[@]} plots to be removed:"
  printf '%s\n' "${ARR[@]}"
  for v in "${ARR[@]}"
  do
    echo "Sleeping for $INTERVAL..." && sleep $INTERVAL
    echo "Removing $v" && rm $v
  done
else
  echo "first argument must be specified manually."

Hi @benjfranklin100 , by default the sorting of the files in directory are alphabetically ordered, hence if u're using the default plot file name which will contain datetime, the oldest file in the directory will be get picked first.

This is just a simple bash (mainly used 1-off during the Chia plot format upgrade), u can clone it into multiple directories if u have multiple plotters
