I`m yet another beginner with both Git hooks and Bash scripting, but I`ve managed to patch something up that might give you an idea, just drop it inside your "pre-receive" hook file: while read oldrev newrev do for commit in $(git rev-list --reverse $oldrev..$newrev) do for file in $(git diff-tree --no-commit-id --name-only -r $commit) do echo "$(git show $commit:$file)" >&1 done done done exit 1 This should reject any push attempt, returning back *content* of each changed file for each new commit. Feel free to adapt as needed, like processing/checking file content instead of sending it over, allowing or rejecting the push accordingly, and also handling corner cases (for example, "oldrev" value of 0000... in case of a new ref creation). I guess there might be better ways (comments welcome), but this should at least get you going... and I`ve learned something new as well ;) Regards, Buga
