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

• git rev-list --objects --all: Lists all objects reachable from any reference.
• git cat-file --batch-check='%(objecttype) %(objectname) %(objectsize) %(rest)': Provides details about each object, including type, name, size, and the rest of the line.
• sed -n 's/^blob //p': Filters the output to include only blob objects and removes the "blob " prefix.
• sort --numeric-sort --key=2: Sorts the output numerically based on the second field (object size).
• cut -c 1-12,41-: Extracts the first 12 characters (object ID) and everything from the 41st character onwards (file name).
• $(command -v gnumfmt || echo numfmt) --field=2 --to=iec-i --suffix=B --padding=7 --round=nearest: Formats the file size to a human-readable format.

Show full ID:

git rev-list --all --objects | grep <blob-id>
git rev-list --all --objects | grep 60cbbaa4850f

# or just rerun without cut
git rev-list --objects --all | git cat-file --batch-check='%(objecttype) %(objectname) %(objectsize) %(rest)' | sed -n 's/^blob //p' | sort --numeric-sort --key=2 | $(command -v gnumfmt || echo numfmt) --field=2 --to=iec-i --suffix=B --padding=7 --round=nearest

Find the commit that has these objects

git log --find-object=<blob-id> --all

Example:

git log --find-object 60cbbaa4850f --all

Find which branch has commit

git branch -a --contains <commit-id>

git reflog show --all | grep <commit-id>
