How to search only first line of git log messages

At day job there are some automated commits made to our git repos with a specific subject: "Job: sync <unique-id> <timestamp>"

A script exists that finds the latest commit of this type and extracts the <unique-id>, using something like: git log --pretty=format:"%s" --grep='Job: sync' -n 1 | awk '{print $3}'

A problem arose when someone created a commit that contains the text "Job: sync" somewhere in the commit message body (not in the first line of the message).

It turns out git log --grep= searches the whole message and not just the subject.

Problem has been partially mitigated by changing --grep='Job: sync' to --grep='^Job: sync' (so it only matches at the beginning of a line). But in theory someone can create a commit message that will also match the new grep pattern.

My question: How do I best search for all commit messages in a git repo that contains a specific text in its subject (first line of the commit message)?

git log --oneline | grep " Job: sync"

A space before the pattern to match the pattern after the commit IDs. Try git log --oneline to see its output.

grep "Job: sync" (without the leading space) to search the pattern everywhere in the subject line.
