As a bit of a interesting insight and guiding hand I've been using the excellent [ncdu](https://dev.yorhel.nl/ncdu) and [rclone's ...clone ](https://rclone.org/commands/rclone_ncdu/) which both work excellently for when 1 folder equates to 1 _media_. With TV shows however this is complicated somewhat. In steps calculating average filesizes in a directory so you can sort them revealing the most notorious offenders. 8 9 I had a quick look online but couldn't find anything that really did what I wanted so I wrote it myself in an extremely verbose fashion. Eventually I slimmed it down to the following function: 10 ``` 11 for i in *; do s=$(du -s "$i" | awk '{print $1}') && c=$(find "$i" -type f -size +1M | wc -l) && echo "$((s / c)) $c $s $i"; done | sort -nr 12 ``` 13 14 What this does is: 15 - Loops every item in the folder using `for` 16 - Calculates the size `$s` using `du` 17 - Counts the items in the folder `$c` using `find` ignoring small files, like subtitles 18 - Divides the two to get the average 19 - Prints the list, then reverse sorts it 20 21 Giving you your results. Ta~da!
