Thanks. But at the same time I have two little doubt. 1. If we have your config: $ git config trailer.sign.key "Signed-off-by: " $ git config trailer.sign.ifexists replace $ git config trailer.sign.command "git log --author='\$ARG' -1 --format='format:%aN <%aE>'" Then I touch a test.c and use: $ git interpret-trailers --in-place test.c without `--trailer`, See what is happen: It seem like your local repo last commit "name <email>" pair have been record in `test.c`. Could this be considered a bug? 2. `git interpret-trailers --in-place` seem like work on git top-dir, If I am in a sub-dir `b` and I want to change a file such as `d.c`, then I must use `git interpret-trailers --in-place b/d.c` to add some trailers. I think the original intention of `--in-place` is to modify a file similar to "$COMMIT_MSG_FILE", so make it run at top-dir, but this is not reflected in the git documentation. This at least confuses people who use this option for the first time. Is it worth modifying? Or is there something wrong with the design of `--in-place`? -- ZheNing Hu
