repository-list.md

🚀 A blazingly fast shell one-liner 🚀

This shell script displays all blob objects in the repository, sorted from smallest to largest.

For my sample repo, it ran about 100 times faster than the other ones found here. On my trusty Athlon II X4 system, it handles the Linux Kernel repository with its 5.6 million objects in just over a minute.

The Base Script

git rev-list --objects --all |
  git cat-file --batch-check='%(objecttype) %(objectname) %(objectsize) %(rest)' |
  sed -n 's/^blob //p' |
  sort --numeric-sort --key=2 |
  cut -c 1-12,41- |
  $(command -v gnumfmt || echo numfmt) --field=2 --to=iec-i --suffix=B --padding=7 --round=nearest

When you run above code, you will get nice human-readable output like this:
