If you have a directory with lot of backups (full backups I mean), when it gets to some size, you could want to empty some space. With this command you'll remove half of the files. The command assumes that your backup files starts with YYYYMMDD or that they go some alphabetical order.

find . -name "*.pdf" -exec pdftk {} dump_data output \; | grep NumberOfPages | awk '{s+=$2} END {print s}'
