to recover files that were added to the index but whose changes were lost (e.g. git reset --hard
)
git fsck --unreachable | grep commit | cut -d\ -f3 | xargs git show
git fsck --unreachable
to get all the items that are unreachable
grep commit
to filter out all entries except for commits (the index will show up as a commit)
cut -d\ -f3
to filter out all but the SHA1s
xargs git show
to show all of the contents of the objects.
Once you've identified the SHA1 that contains the changes that were lost, check it out to get the working tree back into the state of the index at the time git reset --hard
was run.
