Improper use of git lfs migrate --everything somehow generated a .gitattributes file with every known file type. This has basically nuked our project, as all files of every type now look something like this:
version https://git-lfs.github.com/spec/v1
oid sha256:f6d1237f5b00a49b32cca659d9764fc16cf012ea887c3007bf9a2120d7e9fef4
size 792
..throughout the entire repo history. The containing directory is still roughly the same filesize which gives me hope that there is a way of recovering this, but I haven't been able to work it out myself.
Due to unusual circumstances this repo was not yet on github - there's a copy of the repo that we can restore to if needed but would mean losing a couple of days work.
Is there any way to undo the lfs command?
This is how the .gitattributes file ended up being generated somehow:
