We need to provide `--trailer sign` since the command won’t output anything if you don’t give it an input and/or a `--trailer`. Furthermore, the message which already contains an s-o-b is wrong: $ git interpret-trailers --trailer sign <msg.txt Signed-off-by: Alice <alice@xxxxxxxxxxx> Signed-off-by: Alice <alice@xxxxxxxxxxx> This can’t be what was originally intended. So change the messages in this example to use the typical “subject/message” file.
