I wanted to find the 10 largest files in my repository. The script I came up with is as follows:
REP_HOME_DIR=
max_huge_files=
An improvement to raphinesse's answer, sort by size with largest first:
git rev-list --objects --all \
| git cat-file --batch-check='%(objecttype) %(objectname) %(objectsize) %(rest)' \
| awk '/^blob/ {print substr($0,6)}' \
| sort --numeric-sort --key=2 --reverse \
| head \
| cut --complement --characters=13-40 \
| numfmt --field=2 --to=iec-i --suffix=B --padding=7 --round=nearest
