Having backed up the corrupt state, another option is to just try running the reverse command: find .git -name '*.*' -exec sed -i 's/ /\t/g' {} \; I had a quick grep over some pack indices here and ' ' doesn't occur in any of mine whereas '\t' is very common so you may find that the only ' ' sequences are the ones you introduced.
