Bash script which will:
- Iterate all commits made within a Git repository.
- List every object at each commit.
- Order unique objects in descending size order.
Useful for removing large resources from a Git repository, for instance with migrations into GitHub where individual objects are limited to 100MB maximum.
$ ./gitlistobjectbysize.sh

Note
For git
version 2.38.0
and above, the git ls-tree --format
argument will provide a more succinct report output, used via the gitlistobjectbysize-git2.38.0.sh
script variant.
If we now wish to remove something/really/large.iso
we can rewrite history using git filter-branch
:
$ git filter-branch \
--tree-filter "rm -f something/really/large.iso" \
-- --all
Ref 'refs/heads/main' was rewritten
It worked for me ! Thank you very much for help ..
